M. Murano (NSMT-Cr 32874) .</p><p>Diagnosis. Body integument somewhat weakly calcified.</p><p>Carapace (Fig. 1a, b) feebly granulated on dorsal and dorso-lateral surfaces; rostral plate developed, covering basal 2 segments of antennular peduncle and eye-stalk, anterior part slightly narrower than basal part, and anterior margin distinctly concave; antero-lateral tooth well developed, gently curving inwards; rostral process rather long, slightly curving upwards, apex falling just short of anterior tooth of antennal scale; post-ocular process absent; dorsal median carina on posterior part indistinct or bluntly ridged; postero-lateral tooth (= alar spine) moderately long, directed slightly upwards.</p><p>Abdomen (Fig. 1c) with ventral median tooth on first 5 somites, decreasing its height posteriorly; sixth somite sub-equal in length to fifth, with very short postero-lateral tooth; pleura on fourth and fifth somites ending in small spine but those on first 3 somites rounded, without tooth or spine.</p><p>Telson (Fig. 1c, d) about 2.5 times as long as sixth abdominal somite, with obtuse dorsal median tubercle in basal part, armed laterally with single, or rarely 2 setal-spines on either side, in addition to ordinary 2 distal pairs, penultimate pair of which close to terminal pair, less than half length of longest terminal pair; posterior plate weakly produced, bearing 4–6 short spinules and possible 1 pair of plumose setae.</p><p>Uropod (Fig. 1c, d) with both rami sub-equal in length, exopod ending laterally in distinct tooth.</p><p>Antennular lamina (Fig. 1e) with distal margin almost rounded or weakly advanced lobe, and disto-median part with short triangular process, with long seta arising from concaved part.</p><p>Antennal scale (Fig. 1f) sub-triangular, broadest in basal part, twice or slightly longer than broad, apical tooth rather long, directed straightly forward or very gently curving inwards, outer margin weakly convex, bearing 4 or 5 teeth increasing in length towards apex on its anterior half.</p><p>Remarks. This species was well-documented by Băcescu (1985) and Casanova (1996) (see also Hansen, 1910; O. S. Tattersall, 1960).</p><p>Casanova (1996) mentioned that L. hawaiensis Fage, 1940 could be a junior synonym of L. intermedius on the basis of the published data. To date, this might be a common taxonomic concept among the mysid researchers (e.g., WoRMS, accessed in March 2024), although O. S. Tattersall (1960) noted that these two species can be distinguished by several features such as tubercles on the carapace, the rostral length, as well as the shapes in the anterior margin of the antennular lamina.</p><p>So far documented, the form of the antennular lamina referred to L. intermedius appears to show some variations in its form, from well produced wide to short triangular or denticular or even undeveloped plain lobe (Hansen, 1910; Băcescu, 1985; Casanova, 1996; this study). However, it deserves future studies in details to verify the taxonomic status for a little-known Hawaiian species based on further specimens by incorporating molecular data.</p><p>Distribution. This species is currently believed to be distributed in the western Pacific and its neighbouring regions, under a synonymy over L. hawaiensis, from Hawaii to New Caledonia, and eastern part of the Indian Ocean, through South-east Asian waters.</p></div>	https://treatment.plazi.org/id/03D7725CFFDFFFAEDCCEFBE8FEAF314B	Public Domain	No known copyright restrictions apply.

Murano (NSMT-Cr 32881) .</p><p>Diagnosis. Integument of body (Fig. 2) somewhat calcified.</p><p>Carapace (Figs. 2, 3a–c) with small tubercles or processes of different sizes and shapes scattered on dorsal and dorso-lateral surfaces; stout post-orbital processes present and median dorsal carina marked on posterior part; rostral plate wide, completely covering eye-stalks as well as basal 2 segments of antennular peduncle, antero-lateral part with short but distinct tooth; rostral process rather long with slightly upturned apex extending beyond antennular lamina and/or barely reaching tip of antennal scale; postero-lateral part with short tooth (alar spine) directed obliquely upwards, sometimes very feebly toothed or rarely indistinct.</p><p>Abdomen (Fig. 2) in both sexes with sharp ventral median tooth on anterior 5 somites, among which second one is strongest, then decreasing its height posteriorly; pleuron of fifth somite ending in small postero-ventral tooth; sixth somite about 1.5 times as long as fifth, its ventral margin with strong tooth at mid-length as in postero-ventral part.</p><p>Telson (Figs. 2, 3d, e) about twice length of sixth abdominal somite, marked median dorsal tubercle present on basal part, dorsal surface slightly sulcate; lateral margin commonly with 2, rarely single, pairs of setal-spines; posterior margin with orginal 2 pairs of strong setal-spines; distal lamina between strong terminal setal-spines less produced but broad, bearing 8 small setal-spines and 1 pair of long plumose setae.</p><p>Exopod of uropod (Figs. 2, 3d, e) slightly shorter than endopod, outer margin smooth and naked, ending in tiny process; endopod extending well beyond posterior lateral setal-spines of telson.</p><p>Antennular lamina (Fig. 3f) with anterior margin providing short projection in median part together with widely rounded major projection, thus forming convexity and 1 long seta arising from concaved part between small and large projections.</p><p>Antennal scale (Fig. 3 g) sub-triangular in general shape, about 1.5 times as long as broad, with strong distal tooth slightly curving inwards, and weakly convex outer margin bearing 2 or 3 obtuse denticles on anterior half.</p><p>Remarks. Tattersall (1960) considered that Lophogaster japonicus could be a junior synonym of L. pacificus . Contrary to this, Murano (1970) pointed out that L. japonicus is a good species, and it can be distinguishable from L. pacificus in the shapes of the antennular lamina, antennal scale, and rostral length.</p><p>In addition to these points, as briefly noted by Murano (1970), L. japonicus has a relatively short uropod and the carapace is armed with slightly low and obtuse tubercles when compared with those of L. pacificus . Unfortunately, Băcescu (1981, 1985, 1991) was unaware about the paper by Murano (1970), while Casanova (1996) regarded L. japonicus to be a valid species.</p><p>Although L. japonicus is little-known for its morphological features, this species is remarkable among the members within the genus in having a sub-triangular antennal scale with two or three obtuse denticles on its outer margin. In addition, this species is characterised by having a combination of following features: antennular lamina with anterior margin with widely rounded major protrusion together with inner short projection; carapace with post-ocular process and numerous tubercles on dorsal surface as well as somewhat short postero-lateral spine; telson with one or two pairs of setal-spines on its lateral margin.</p><p>One ovigerous female (NSMT-Cr 32881) and small specimens (NSMT-Cr 32877, -32878) devoid of a marked postero-lateral carapace tooth (alar spine); nevertheless other features agreed well with those of this species.</p><p>Distribution. This species is recorded with certainty from the western North Pacific, and commonly captured off the Pacific coasts of Japan, and in depths from 50–300m (W. M. Tattersall, 1951; Murano, 1970; Saitoh and Kajihara, 2002; Fukuoka, 2009).</p></div>	https://treatment.plazi.org/id/03D7725CFFDDFFA8DCEDFCE6FCE636CD	Public Domain	No known copyright restrictions apply.

This species shows marked sexual dimorphisms in the rostral plate and rostral process as females have a much longer rostral plate as well as longer rostral process than those of males (see also Casanova, 1993).

This species is diagnosed by having a combination of several remarkable characters: the carapace shows a rather smooth surfaces, with a well-developed rostral plate possessing a relatively long rostral spine reaching or extending far beyond the antennular peduncle, together with a long postero-lateral tooth (= alar spine); the second to fifth pleura of the abdomen armed with postero-ventral teeth; and the sixth abdominal somite with a long tooth at the postero-lateral end.</p><p>Distribution.

Although Băcescu (1981) (see also Hansen, 1910, Pl. 1, fig. 2b) showed the presence of two stout inner basal spines on the antennal flagellum, only a single spine can be seen in our specimens. In addition, the ventral spine on the endopod of the uropod appears to be less developed as compared with that shown by Băcescu.</p><p>Müller (1993) regarded that Paralophogaster glaber pacificus reported by Vereshchaka (1990) from the waters around the Nazka and Sala y Gómez ridges could be a synonym of P. glaber . However, as noted by Hernández-Payán (2023), the structure of the telson of the south-eastern Pacific specimens differs from that of the western Pacific population (e.g., Hansen, 1910; W. M. Tattersall, 1951; Băcescu 1981, 1991; Casanova, 1996).</p><p>Contrary to this, Hernández-Payán (2023) mentioned that their specimens collected off Chile showed the typical form of the western Pacific population in the identical part.</p><p>Thus, the identity of the south-eastern Pacific subspecies of P. glaber should be re-assessed in the future studies. Furthermore, a taxonomic review for such eurychoric species is strongly recommended over its geographical scale in order to verify the origin and/or diversification of the local populations.</p><p>Distribution. According to the published literature, this species is known to distribute in the Atlantic and Indo-Pacific Oceans (see W.M.

Integument of body (Fig. 8) rather fragile.</p><p>Carapace (Fig. 9a, b) with rostral plate somewhat pentagonal in dorsal view, not converging posteriorly but running almost parallel to each other; anterior margin feebly convex or nearly straight, leading to short median rostral tooth: pair of short teeth placed antero-lateral corner; lateral parts of rostral plate curving upwards, forming well marked elevated rims in lateral aspect; small median dorsal tubercle present just posterior to rostral plate.</p><p>Telson (Fig. 9c) as long as or slightly longer than sixth abdominal somite, gradually narrowing posteriorly, with 5–7 short setal-spinules along lateral margin; moderately large sub-terminal setal-spine falling far short of posterior end of telson and much shorter than terminal setal-spines, bearing 4 or 5 moderate setal-spines increasing in length posteriorly between terminal and sub-terminal stout spines; postero-median plate noticeable, most probably with 5 denticles and 4 plumose setae.</p><p>Uropod (Fig. 9d) with endopod commonly with 2, infrequently 3, moderate setal-spines in basal part of ventral side.</p><p>Eye (Fig. 9a, b) with cornea 1.60–1.75 times as broad as rostral plate.</p><p>Antennal scale (Fig. 9a, b) rather long, extending beyond antennular peduncle by about 1/3 length of blade, about 4 times as long as wide; lateral margin nearly straight, bearing short tooth falling far short of anterior end of blade; sub-terminal suture present.</p><p>Distribution. This species is known from Japan, Philippines, Indonesia, and New Caledonia, and captured in abundance around the Japanese coastal waters. According to our survey, this species appears to commonly inhabit in depths shallower than 200 m.</p></div>	https://treatment.plazi.org/id/03D7725CFFD5FFA2DE8DFDF0FC4E3343	Public Domain	No known copyright restrictions apply.
