Aphos is monotypic.  Porichthys contains 14 species, seven of which were included in the present study.</p><p>The second preural centrum and first ural centrum are relatively elongate in  Porichthyinae, with the length of the centra ranging from 1.3 to 1.5 times their depth, whereas the length of the second ural centrum is approximately two-thirds that of the first ural centrum. There is a dorsal prezygaphophysis on the neural spine of the second preural centrum that is prominent and contacts the neural spine of the preceding vertebra in all  Porichthyinae; the size of the ventral prezygapophysis on the haemal spine of the second preural centrum is variable in the subfamily [absent in  Porichthys greenei (UF 226105, 60.7 mm SL),  Porichthys porosissimus (Cuvier, 1829) (MZUSP 45398, 40.0 mm SL) and  Porichthys margaritatus (Richardson, 1844) (USNM 101730, 19.3 mm SL)]. Although absent in most  Porichthyinae, a ventral postzygapophysis on the second preural centrum was found in two specimens of  Porichthys notatus (VIMS 38017, 84.0 mm SL and VIMS 38018, 84.8 mm SL), one specimen of  Porichthys plectrodon Jordan &amp; Gilbert, 1882 (USNM 302134, 75.5 mm SL), one specimen of  Porichthys margaritatus (UF 226009, 70.2 mm SL) and most specimens of  Aphos porosus (Valenciennes, 1837); in all of these individuals, the postzygapophysis is substantially smaller than the prezygapophysis. Although the occurrence of a ventral postzygapophysis on the second preural centrum varies individually, members of  Porichthyinae were the only taxa of  Batrachoidiformes to have this process (Fig. 11A, C).</p><p>A dorsal prezygapophysis on the first ural centrum is present in most representatives of  Porichthyinae, although its prominence varies both intraspecifically and ontogenetically [absent only in two specimens of  Porichthys porosissimus (MZUSP 45398, 40.0 and 34.5 mm SL); and a single specimen of  Porichthys pauciradiatus (UF 226549, 44.6 mm SL); for an example of ontogenetic variation, see Fig. 13]. A ventral prezygapophysis on the first ural centrum is present in most examined specimens of  Aphos porosus,  Porichthys notatus,  Porichthys margaritatus and the  Porichthys porosissimus /  plectrodon species complex. Neural and haemal spines of the second preural centrum are elongate and are 1.1–2 times longer than the spines of more anterior preural vertebrae. Two specimens of  Porichthys notatus (VIMS 38017, 84.0 mm SL and FMNH 122401, 120.2 mm SL) have a small, circular posthaemal cartilage of the second preural vertebra (Fig. 11A).</p><p>Each hypural supports five or six principal caudal-fin rays, with the ventral hypural usually supporting one ventral procurrent caudal-fin ray (although the support for the ventral procurrent ray varies intraspecifically; see Table 2). One or two dorsal procurrent rays are present. Two dorsal procurrent rays, both supported by the posterior epural, is the most common condition. One specimen of  Porichthys greenei (UF 220105, 60.71 mm SL) does not have any procurrent rays. The single ventral procurrent caudal-fin ray is supported by either the ventral hypural or the distal caudal radial cartilage of parhypural  .</p><p>The margin of the parhypural flange varies from deeply to slightly concave, although it is almost straight in some specimens ( Porichthys bathoiketes Gilbert, 1968 UF 228539, 73.5 mm SL). The articular edge of the parhypural flange projects anteroventrally, forming an acute stay that articulates with the haemal spine of the second preural centrum. A distinct triangular spine projects from the tip of the acute stay of the parhypural flage in most examined specimens (Figs 11–14). In  Porichthys, the entire margin of the parhypural has spine-like projections.</p><p>The epurals of  Porichthyinae lie at a narrow angle (&lt;40°) relative to the longitudinal axis. The outline of the epurals varies from slightly convex ( Porichthys porosissimus VIMS 1132, 55.7 mm SL) to curved ( Porichthys porosissimus /  plectrodon USNM 302134, 56.1 mm SL), although there is substantial individual variation in some species (see accounts for species of  Porichthys below).</p><p>Aphos: The epurals of  Aphos porosus are markedly curved posteriorly, with a similar outline to that of most species of  Porichthys (e.g.  Porichthys notatus; see specific accounts for further details); the posterior epural supports both the first and second procurrent fin rays. One specimen (USNM 309739, 152.3 mm SL) has a long anterior epural that supports the first procurrent caudal-fin ray (Fig. 11F); the anterior epural supporting a procurrent fin rays was not observed in other members of  Porichthyinae .</p><p>A ventral prezygapophysis on the first ural centrum of  Aphos porosus is present in some specimens (e.g. USNM 309738, 77.5, 89.4 and 98.6 mm SL), but absent in others (USNM 309738, 152.3 mm SL and USNM 305505, 151.4 mm SL). Most specimens have a small ventral postzygapophysis on the haemal arch of the second preural centrum.</p><p>Porichthys: All species of  Porichthys bear spine-like projections on the margin of the parhypural flange. Although the number, orientation and prominence of the spines are both inter- and intraspecifically variable, all examined specimens of  Porichthys have one or more spines projecting from the margin of the parhypural flange, in addition to the spine in the articular edge (Figs 11–14).</p><p>Porichthys bathoiketes: The epurals vary intraspecifically in  Porichthys bathoiketes . In the paratype (UF 12965, 93.8 mm SL), the posterior epural has its anterior tip contacting the midpoint of the anterior epural. This displacement of the posterior epural shifts the first procurrent fin ray away from the anterior epural. In UF 228539 (73.5 mm SL), the epural bones are similar to those observed in most species of  Porichthys, i.e. the epurals are parallel to each other and the anterior epural contacts the first procurrent ray (Fig. 11B). The epurals of this specimen have sharply tapered anterior tips that curve slightly to become parallel to the body axis, which is reminiscent of the condition found in  Porichthys cf. plectrodon (see below); posteriorly, the epurals are convex. In the paratype (UF 12965), anterior tips of the epurals are blunt.</p><p>Porichthys greenei: In  Porichthys greenei, the distal tip of the anterior epural contacts the anterior margin of the posterior epural instead of extending posteriorly to contact the bases of the procurrent caudal-fin rays, as observed in all other species of  Porichthys (Fig. 12).  Porichthys greenei has extensions on the proximal region of the epurals that vary from a digitiform projection from the anterior tip (UF 226105, 60.7 mm SL) to a wide trapezoidal flange that extends most of the length of the epural (UF 226105, 44.0 mm SL). The triangular flanges on the posterior epural are typically smaller than those on the anterior epural and are restricted to its proximal edge. A flange is absent on the posterior epural in UF 226105 (60.7 and 50.7 mm SL).</p><p>Porichthysgreenei isuniqueamongBatrachoidiformes in having reduced counts of caudal-fin rays, with ten principal caudal-fin rays (I, 4, 4, I) and a single ventral and dorsal procurrent caudal-fin ray.The only exception is UF 2260105 (60.7 mm SL), which has no dorsal procurrent rays but does have six dorsal principal caudal-rays; this might have been the result of damage and regeneration of the first dorsal principal ray.</p><p>The parhypural flange is concave in  Porichthys greenei but presents remarkable variation in the number, shape and prominence of spines (Fig. 12). As in all species of  Porichthyinae, there is a distinct spine in the articular edge of parhypural (albeit weakly developed in UF 226105, 60.7 mm SL). Two specimens (UF 226105, 56.2 and 44.0 mm SL) have two additional prominent spines in the centre of the margin of the parhypural flange that are two times longer than the spine at the articular edge of the parhypural flange. In contrast, specimen UF 226105 (37.1 mm SL) has a single medial spine and UF 220105 (60.7 and 50.7 mm SL) has no other spines in the parhypural flange, although they have weak indentations in the posterior region of the flange.</p><p>The structure of the neural spine of the second preural centrum is intraspecifically variable in  Porichthys greenei . A full neural spine of the second preural centrum, including an elongate rod-like distal portion with a cartilaginous core, is present in some specimens (UF 226105, 50.7 and 37.1 mm SL; Fig. 12A, B), whereas the distal portion is lacking in others (UF 226105, 60.7 and 56.2 mm SL; Fig. 12C, D). One specimen (UF 226105, 44.0 mm SL) has a distinct distal component, although it is reduced and does not extend beyond the distal tip of the proximal component of the neural spine of the second preural centrum. Some specimens (UF 2206105, 50.7 and 37.1 mm SL) have two neural spines on the second preural centrum; the larger specimen also has two haemal spines on the second preural centrum. As in other taxa, this individual plasticity is likely to be a response to malformation of vertebral bodies during development (Witten &amp; Hall, 2015)  .</p><p>Porichthys margaritatus:  The parhypural flange is straight to slightly concave in this species. The only exceptions observed were in one specimen (UF 226009, 70.3 mm SL) that has a sharp indentation at approximately the midpoint of the flange, and in another (USNM 101730, 33.40 mm SL) that bears two anterior bulges, both of which are slightly smaller than the spine on the articular edge .</p><p>Spines on the parhypural flange, as observed in all other species of  Porichthys, were found only in the largest specimen examined (UF 226009, 99.2 mm SL; Fig. 11C), which has a small triangular anterior spine in the anterior region of the flange. All other specimens have only a distinct spine on the articular edge of the parhypural flange (Fig. 13). Larger specimens could not be examined to determine whether this variation is attributable to ontogenetic or individual variation.</p><p>The epurals in most specimens of  Porichthys margaritatus are simple rod-shaped elements that lack flanges or other outgrowths. However, in three specimens a short trapezoidal flange projects from the anterior extremity of the anterior epural (UF 226009, 89.4, 78.8 and 70.3 mm SL)  .</p><p>The prominence of the dorsal prezygapophysis on the first ural centrum is highly variable, ranging from highly developed and contacting the base of the neural arches of the second preural centrum (UF 226009, 99.2 mm SL) to weakly developed (USNM 101730, 19.3 mm SL). This is likely reflective of ontogenetic variation, because smaller specimens typically have</p><p>Columns ‘Dorsal hypural’ and ‘Ventral hypural’ indicate the number and type of fin ray supported by each hypural. Columns ‘Epural 1’ and ‘Epural 2’ represent the number of procurrent fin rays supported by the anterior and posterior epurals, respectively.</p><p>Abbreviations: Br, branched caudal-fin ray; N, number of specimens examined; NBr, caudal-fin rays not branched (includes principal and procurrent).</p><p>reduced or even absent dorsal prezygapophyses (UNSM 101730, 19.3 and 27.9 mm SL), whereas in the two largest specimens examined (UF 226009, 99.2 and 89.4 mm SL) these processes are well developed (Fig. 13). The smallest specimen to have a prominent dorsal prezygapophysis is 33.4 mm SL (USNM 101730). The specimen UF 226009 (70.2 mm SL) has a relatively small ventral postzygapophysis on the haemal arch of the second preural centrum (about half the depth of dorsal prezygapophysis on the first ural centrum). Another variation observed in this species concerns the presence of two neural spines on the second preural centrum (USNM 101730, 39.2 mm SL and UF 226009, 89.4 and 70.2 mm SL), with the last of these specimens also having two haemal spines.</p><p>Porichthys notatus: In this species, the dorsal prezygapophysis of the first ural centrum is prominent and contacts the base of the neural spine of the second preural centrum in all examined specimens. The margin of the parhypural flange varies from straight to concave (USNM 104503, 98.3 mm SL and FMNH 122401, 120.2 mm SL, respectively). The spines on the parhypural flange are less prominent in  Porichthys notatus than in other members of the genus. Although all specimens have a distinct spine on the articular edge of the parhypural flange, only USNM 104530 (98.2 mm SL) has a distinct spine in the anterior quarter of the parhypural flange. Specimens USNM 104530 (98.3 mm SL) and VIMS 38017 (84.0 mm SL) were found with a short indentation on the anterior part of the flange (Fig. 11A). FMNH 122401 has a continuous margin of the parhypural flange, without any spine or indentation, except for the one on the articular edge.</p><p>Other intraspecific variations include the presence of a postzygapophysis on the second preural centrum and the occurrence of distal caudal cartilages. Two specimens (VIMS 38017, 84.0 mm SL and USNM 104503, 98.2 mm SL) have weakly developed ventral postzygapophyses on the haemal arch of the second preural centrum, which are approximately half of the depth of the ventral prezygapophysis on the first ural centrum. Thus, specimen VIMS 38107 was the only specimen of  Batrachoidiformes to have a dorsal postzygapophysis on the second preural centrum (Fig. 11A); this process is small, with its length only about one-third that of the dorsal prezygapophysis on the first ural centrum. Specimens FMNH 122401 (120.2 mm SL) and VIMS 38017 (84.0 mm SL) have a small, circular posthaemal distal cartilage of the second preural centrum; no other specimen of this species examined has this element  .</p><p>Porichthys pauciradiatus: This species is unique among  Batrachoidiformes in having a single epural bone (Fig. 11E). This condition was observed in both examined specimens, and is found otherwise only in other groups of fishes, such as in  Gobiidae (Fig. 31A),  Callionymidae (Fig. 31D),  Achiridae (Fig. 32C),  Lophiiformes (Monod, 1968) and  Gobiesocidae (Konstantinidis &amp; Conway, 2010), among others. The epural is elongate and has an enlarged anterior base (approximately four times wider than its posterior tip), which bears anterior and posterior flanges. The anterior flange is trapezoidal and has an irregular margin and an anterior digitiform projection. The posterior flange is thinner than the anterior one and has a semi-elliptical outline. An elliptical foramen is present on the base of the epural.</p><p>The cleared and stained specimen examined (UF 226549, 44.6 mm SL) has no dorsal prezygapophysis on the first ural centrum, but the specimen examined with CT (UF 226549, 50.24 mm SL) has a dorsal prezygapophysis. We could not determine whether this is an ontogenetic (as observed in  Porichthys margaritatus) or individual variation. However, we note here that, although the female specimen that lacks the process is relatively small (44.6 mm SL), it has reached or is close to maturity, because it has developed ovaries with large oocytes. In all other species of  Porichthys, specimens at this length have a distinct dorsal prezygapophysis.</p><p>Porichthys porosissimus /  plectrodon species complex: In this study we did not distinguish species of  Porichthys plectrodon and  Porichthys porosissimus . Gilbert &amp; Kelso (1971) proposed that  Porichthys porosissimus has a restricted distribution in southern Brazil and Uruguay, whereas  Porichthys plectrodon is distributed from coastal areas of central Brazil to the Mid-Atlantic Bight of the east coast of North America. The material examined to date includes specimens from both geographical regions, but the morphological characters proposed by Gilbert &amp; Kelso (1971) to differentiate these species (gill raker counts and otolith shape) were not observed in specimens from both geographical regions. To avoid misleading inferences regarding the variation observed, we describe the caudal skeleton of these species as a single species complex.</p><p>The specimens of the  Porichthys porosissimus /  plectrodon species complex examined have a pair of spines on the articular edge of the parhypural flange, which is in contrast to the single spine observed in all other representatives of  Porichthyinae . However, this condition might reflect a plesiomorphic character, because two small spines in the articular edge of the parhypural flange were observed among the species of Batrachoidinae and Thalassophryinae.</p><p>Dorsal prezygapophyses on the first ural centrum were found in all specimens&gt; 48 mm SL. A single specimen of the  Porichthys porississimus /  plectrodon complex was found to have a small ventral prezygapophysis on the first ural centrum (MZUSP 45398, 35.0 mm SL); however, the occurrence of this ventral process is considered to be an intraspecific variation, because all other examined specimens lack ventral prezygapophyses.</p><p>The epural bones are simple, varying from slightly convex to concave. The anterior tip of the anterior epural in MCZ 170729 (150.8 mm SL) is curved and contacts the neural spine of the second preural centrum. The anterior epural has a flange in the proximal edge, of variable prominence; it is distinct and trapezoidal in one specimen (VIMS 1132, 55.7 mm SL; Fig. 11D) but slender in another (VIMS 1132, 81.6 mm SL). The epurals of MZUSP 45398 (40.0 mm SL) have angular extensions projecting from the anterior tip of both bones .</p><p>The parhypural flange has two conspicuous spines at the midpoint region, which are highly protruded in VIMS 1132 (55.71 mm SL; Fig. 11D). Specimens from the North Atlantic (e.g. VIMS 1132) bear an additional spine on the anterior portion of the paryhypural flange (Fig. 11D). MZUSP 45398 (40.0 mm SL) has only a pair of spines at the articular edge of the parhypural flange, but lacks spines on the posterior region of its margin. The dorsal prezygapophysis of the first ural centrum is small and does not reach the origin of the neural arches of the second preural centrum. As in  Porichthys margaritatus, the prominence of dorsal prezygapophyses likely reflects ontogenetic variation; the largest dorsal prezygapophysis was observed in the largest specimen (VIMS 1132, 81.6 mm SL), whereas the dorsal prezygapophysis is absent in the smallest specimen examined (MZUSP 45398, 34.5 mm SL).</p><p>Other intraspecific variations observed include two neural spines on the second preural centrum (MZUSP 45398, 34.5 mm SL) and a marked hook-like process projecting from the posterior margin of haemal spine of the second preural centrum (VIMS 1132, 81.6 mm SL).</p><p>Porichthys cf. plectrodon: The six specimens examined in the lot USNM 302134, which were collected from the northeastern coast of Brazil, have similar gill raker counts and otolith shape to specimens from the northern Atlantic; therefore, they do not allow confident identification between  Porichthys porosissimus and  Porichthys plectrodon, following the criteria proposed by Gilbert &amp; Kelso (1971). However, all examined specimens of USNM 302134 were consistently found to have a distinctive hockey-stick-shaped posterior epural; this shape was not found in any other species of  Batrachoidiformes (Fig. 11). Given the consistent dissimilarity between the shape of the epurals of the specimens of this lot and of the other specimens of the  Porichthys porosissimus /  plectrodon complex, we describe the morphology of these specimens separately. Based on locality, we suggest that these might represent  Porichthys plectrodon, although a full taxonomic revision of this species complex is warranted.</p><p>The posterior epural is convex posteriorly (most prominent in two specimens: 48.7 and 56.1 mm SL), but the proximal region curves anteriorly, resulting in a posterior epural with a hockey-stick shape. The base of the posterior epural is more gently curved in a 53.5 mm SL (Fig. 14B) specimen than in other specimens, but the curvature is greater than that observed in  Porichthys bathoiketes (UF 228539; Fig. 11B); all other species of  Porichthys have straight posterior epurals. The shape of the anterior epural varies from convex to concave, with an anterior flange extending through the proximal region and a digitiform outgrowth at the proximal tip (this latter projection is absent in the 53.5 mm SL specimen).</p><p>The parhypural flange of specimens from this lot has a regular sinuous outline, with a proximal angular projection that bears a spine, followed posteriorly by a shallow concavity (Fig. 14). The 56.1 mm SL specimen has a sharp indentation on the posterior third of the flange. Specimens of the  Porichthys porosissimus /  plectrodon complex typically have a pair of spines in the articular edge of the parhypural flange, but a 48.7 mm SL specimen from this lot has an additional spine projecting proximally from the pair of spines on the anterior edge. Two larger specimens (77.1 and 56.1 mm SL) have another spine between the anterior edge and the proximal projection.</p><p>Dorsal prezygapophyses on the first ural centrum were observed in all examined specimens of USNM 302134 (N = 6). As in  Porichthys margaritatus, the prominence of this process increases during ontogeny. The smallest examined specimen (48.7 mm SL) bears weakly developed dorsal prezygapophyses, whereas these processes are greatly developed and contact the base of the neural spine in larger specimens (56.1 and 77.7 mm SL). Two specimens (53.5 and 75.5 mm SL) were found to have a small ventral prezygapophysis on the first ural centrum, the length of which is approximately half that of the dorsal prezygapophysis. The 75.5 mm SL specimen has a small ventral postzygapophysis on the second preural centrum, similar to the size of the ventral prezygapophysis of the first ural centrum. The posterior margin of the haemal spine of the 56.1 and 53.5 mm SL specimens has hook-like projections, which in the smaller specimen contact the articular edge of the parhypural flange. Other variation includes two neural spines on the second preural centrum on the 77.7 mm SL specimen  .</p></div>	https://treatment.plazi.org/id/039C87B1FF9D1F619D9DFE2E60F0FF03	Public Domain	No known copyright restrictions apply.

Daector contains four species, with two of them examined in this study.  Thalassophryne has six species, three of which were examined in this analysis.</p><p>The first ural and and second preural centra are slightly elongated, with the length of the centra approximately equal to their depth in  Thalassophryne, but 1.3 longer in  Daector . The length of the second ural centrum is roughly two-thirds that of the first ural centrum. Neither dorsal nor ventral zygapophyses are present in the ural centra of any specimen of  Thalassophryninae . The second preural centrum bears a blunt or hook-like dorsal prezygapophysis that contacts the base of the neural arch of the preceding vertebra. The neural and haemal spines of the second preural centrum are 1.3–2 times longer than the more anterior spines on the caudal vertebrae.</p><p>The dorsal hypural supports five or six principal caudal-fin rays, whereas the ventral hypural supports six or seven caudal-fin rays (six principals and one procurrent). Two dorsal and one or two ventral procurrent caudal-fin rays are present in most species of this subfamily. The only exception is  Thalassophryne amazonica Steindachner, 1876, which lacks procurrent fin rays (Fig. 18; Table 3). The dorsal procurrent rays are supported by the epurals. The anterior (or single) ventral procurrent caudal-fin ray is supported by the distal caudal radial cartilages. The homology of these cartilages, however, is uncertain. The only specimen in which the distal caudal radials stained was of  Daector dowi (USNM 206532, 79.1 mm SL; Fig. 15A), which has two small and circular distal caudal radial cartilages. The topology of these cartilages indicates that they are either distal caudal radials of the haemal spine of the second preural centrum or of the parhypural. The second ventral procurrent caudal-fin ray, if present, is supported by the ventral hypural.</p><p>The parypural flange varies from straight to strongly concave, and its articular edge is robust and may have indentations or spinations. The morphology of the articular margin of the parhypural flange is variable in  Daector dowi, with some specimens having an acute articular edge that articulates loosely with the haemal spine of the second preural centrum (UF 226263, 43.1 mm SL).</p><p>The largest juvenile specimens of  Thalassophryne and  Daector that were examined have a short hypurapophysis-like process on the lower third of the lateral wall of the first ural centrum that projects slightly in a lateral direction to form a narrow shelf, forming additional surface area for the origin of the m. hypochordal longitudinalis (Fig. 15E, F). The hypurapophysis-like process of  Thalassophryninae develops late in ontogeny. In the smallest examined specimens ( Thalassophryne maculosa Günther, 1861, USNM 200558, 25.0 and 36.0 mm SL), the hypurapophysis-like process is not yet developed.</p><p>The epurals have a simple rod-like shape. In most species they are convex, but in some specimens of  Daector dowi the epurals are concave (see below). The distal tips of both epurals supports caudal-fin rays in  Daector . In  Thalassophryne, the posterior epural supports the anteriormost non-branched fin rays (which may be either procurrent or the unbranched ray of the principal series), whereas the anterior epural does not support any fin rays (although the distal tip of the anterior epural may contact the anteriormost procurrent fin ray in  Thalassophryne).</p><p>Daector: The hypurals support 11 principal caudal-fin rays (I, 4, 5, I), with the exception of a single specimen of  Daector dowi (UF 226263, 84.0 mm SL), which has six dorsal principal caudal-fin rays (formula I, 5, 5, I). The total counts of fin rays of this specimen are the same as in other specimens (15), having a single dorsal procurrent ray instead of two as observed in all other specimens of  Daector dowi . The morphology of the unbranched principal fin ray observed in other specimens and the dorsalmost branched caudal-fin ray of this specimen (UF 226263, 84.0 mm SL) is similar (i.e. slightly thinner than other principal fin rays), and they appear to be homologous. Therefore, it is likely that the posterior tip of the corresponding unbranched principal fin ray of UF 226263 (84.0 mm SL) branched during ontogeny, resulting in a branched fin ray.</p><p>Daector reticulata (Günther, 1864) has one ventral procurrent fin ray (Fig. 15B), whereas  Daector dowi has two. The shape of the epurals and their support for procurrent fin rays and the shape of the parhypural flange is variable in  Daector dowi (Figs 15A, 16). The shape of the anterior epural varies from convex (UF 226263, 84.0 mm SL) to straight (UF 226263, 89.6 mm SL). From the 11 cleared and stained specimens examined, the anterior epural of seven specimens has a slender flange on the proximal portion of the anterior margin. The length of this flange varies from weakly developed (UF 226263, 84.0 mm SL; Fig. 16E) to elongate, extending to the midpoint of the anterior epural in UF 226263 (43.1 mm SL; Fig. 16A). The presence and prominence of the flange, such as the curving of the epural, do not appear to be related to ontogeny, because different conditions were observed in specimens of similar size. The anterior epural that does not bear the flange has a rod-like shape. The posterior epural is more consistently straight or slightly convex.</p><p>In most specimens of  Daector dowi, both epurals support caudal-fin rays. However, in one specimen (USNM 206532, 59.7 mm SL) the first and second dorsal procurrent caudal-fin rays are supported by only the posterior epural (Fig. 16C). The anterior epural contacts but does not support the first dorsal procurrent ray, as in  Thalassophryne . Another variation observed in the caudal-fin rays is the presence of three dorsal procurrent rays, with the anteriormost positioned between the neural spine of the second preural centrum and the anterior epural (UF 226263, 74.5 mm SL); this unique occurrence is interpreted as individual variation because all other specimens of  Daector dowi have two dorsal procurrent rays. A similar individual variation (i.e. one dorsal procurrent caudal-fin ray between the neural spine of the second preural centrum and the anterior epural) was observed in  Opsanus beta and  Opsanus pardus .</p><p>The parhypural flange in  Daector is consistently concave, but the curvature of the margin varies from slight (USNM 206532, 59.7 mm SL) to highly concave (UF 226263, 84.0 mm SL). The latter specimen also has a unique elliptical invagination at the midpoint of the margin. The shape and the width of the articular edge of the parhypural flange are also highly variable. The smallest (UF 226263, 43.1 mm SL) and the largest (UF 226263, 89.6 mm SL) specimens examined have an acute anterior edge (Fig. 16A, F). The edge is still angular but is slightly longer in specimens UF 226263 (47.9 and 82.3 mm SL; Fig. 16B) than in UF 226263 (43.1 mm SL). All other specimens examined have a long articular edge of the parhypural, in which the articular surface is also variably shaped. For example, some specimens have a straight articular edge of the parhypural (USNM 206532, 59.1 mm SL and UF 226263, 84.0 mm SL; Fig. 16C, E), whereas in others the articular surface is indented, with three or four spine-like projections [UF 226263, 60.0 mm SL (Fig. 16D) and USNM 206532, 79.2 mm SL (Fig. 15A)]. The variations observed in the morphology of the parhypural flange are not related to ontogeny, because the distinct curvature of the parhypural flange and the width and shape of the anterior edge of parhypural flange were found in specimens of similar size across the available size range, indicating that these differences are a product of individual variation. Another individual variation that was observed in a specimen of  Daector dowi (UF 226263, 43.1 mm SL) was that it has two neural spines on the second preural centrum.</p><p>Thalassophryne: All specimens examined of this genus have the first and second dorsal procurrent fin rays supported by the posterior epural (or the unbranched</p><p>Columns ‘Dorsal hypural’ and ‘Ventral hypural’ indicate the number and type of fin ray supported by each hypural. Columns ‘Epural 1’ and ‘Epural 2’ represent the number of procurrent fin rays supported by the anterior and posterior epurals, respectively.</p><p>Abbreviations: Br, branched caudal-fin ray; N, number of specimens examined; NBr, caudal-fin rays not branched (includes principal and procurrent). *Occurrence in a single specimen.</p><p>principal fin ray in  Thalassophryne amazonica), with the anterior epural not supporting any caudal-fin rays. The only exception is one specimen of  Thalassophryne nattereri Steindachner, 1876 (MZUSP 47262, 114.8 mm SL), in which the first procurrent fin ray is supported by the anterior epural.</p><p>In  Thalassophryne maculosa, the epurals are robust but simple, rod-like elements in large specimens, without flanges. The parhypural flange varies from straight (USNM 199524, 64.4 mm SL) to concave (USNM 199524, 84.2 mm SL) (Fig. 17C–F), and in most specimens it is smooth. USNM 220558 (36.1 mm SL; Fig. 15D) has a short indented articular edge of the parhypural flange. The articular surface of a larger specimen (USNM 199524, 84.2 mm SL; Fig. 17E) is longer than in all other examined specimens (approximately half the length of the parhypural flange) and is slightly irregular in its outline. In most specimens, the length of the articular surface of the parhypural flange is approximately one-quarter of the length of the flange.</p><p>Thalassophryne nattereri has a straight parhypural flange, although its length is highly variable. For example, in specimens USNM 302333 (69.4 and 113.0 mm SL; Fig. 17A, B) the articular edge is short and does not extend beyond the foramen from which the caudal vessels exit, whereas in other specimens [MZUSP 47262, 114.8 mm SL (Fig. 15C) and MZUSP 47283, 70.4 mm SL] the articular edge the parhypural flange is long and extends to the middle of the ventral hypural. The robust epurals are rod-like and do not bear any flanges. In one specimen, MZUSP 47262 (114.8 mm SL; Fig. 15C), the epurals are fused proximally, although the two elements remain distinct. Most specimens of  Thalassophryne nattereri have the first and second procurrent fin rays supported by the posterior epural, as in other species of  Thalassophryne; the only exception is MZUSP 47262, which has the anterior epural supporting the first procurrent fin ray (see Table 3).</p><p>Thalassophryne nattereri  has a total of 16 caudal-fin rays, with I, 5, 5, I as the most frequently observed principal formula. One specimen (MZUSP 47283) was observed to have 14 principal caudal-fin rays (I, 6, 6, I), although the total count of fin rays is the same. This specimen has a single dorsal and ventral procurrent ray, in contrast to two pairs of both dorsal and ventral procurrent rays in other specimens of  Thalassophryne nattereri .</p><p>Thalassophryne amazonica has a unique caudal skeleton among all  Batrachoidiformes in that it does not have any procurrent caudal-fin rays (Fig. 18; Table 3). The overall arrangement of the skeleton is robust, particularly the epurals, which are thicker than the dorsal-fin rays. Furthermore,  Thalassophryne amazonica is distinguished from the other species of  Thalassophryne by the presence of five dorsal principal caudal-fin rays (I, 4, 5, I), in contrast to six dorsal principal fin rays. The parhypural flange has a wide articular edge that extends to the posterior margin of the first ural centrum and has a concave flange. One specimen (ANSP 178103, 76.9 mm SL) bears a unique spear-like process, which arises from the anterior region of the parhypural flange (Fig. 18A).</p></div>	https://treatment.plazi.org/id/039C87B1FF841F6B9E37FEDD61DAFA7C	Public Domain	No known copyright restrictions apply.
