            <p> Genus  Nivcentia Holzinger, 2004</p>
            <p> =  Vincentia Uhler, 1895 (non Laporte de Castelnau, 1872), replaced by  Nivcentia Holzinger by Holzinger (2004: 952). </p>
            <p>Amended description (modified from Fennah 1945a). Small pentastirine cixiids (body length ~4.0– 5.5 mm), light brown to dark brown in coloration.</p>
            <p>Vertex relatively narrow and much longer than wide (length at midline approximately 1.5× width at posterior margin), lateral margins subparallel (diverging slightly caudad); anterior margin approximately transverse or weakly convex (apex carinae), posterior margin triangularly excavate, subapical transverse carina arising laterally in apical third, joining subapically, a small quadrangular areolet at apex between apical and subapical transverse carina; vertex disc distinctly concave, median longitudinal carina absent. Frons plus clypeus (in frontal view) collectively rhomboid (slightly curved in profile), lateral margins expanded laterally to just below level of median ocellus, median carina forked dorsal (forming an areolet contiguous with the areolet of the vertex). Median ocellus present, but indistinct. Frontoclypeal suture in shape of broad, inverse “V”. Clypeus broadly rhomboid bearing a distinct median carina.</p>
            <p>Forewings transparent with few markings, veins bearing conspicuous tubercles on wing veins (setal bases), tubercles present on CuP; stem of composite vein ScP+R very long between basal cell and fork of RP from RA+ScP. Forewing branching pattern RA 2-branched, RP 2-branched, MP 5-branched. Hind tibia bearing a variable number of lateral spines, spinulation 6(5+1)-7-7, platellae absent.</p>
            <p>Male terminalia with narrow periandrium bearing a series of processes, usually four elongate and slender processes including a sinistral and dextral process (sensu Mead and Kramer, 1982), a medioventral process, and a mediodorsal process. Endophallus basally broad, strongly bent left (in ventral view), with apex acuminately elongated, strongly narrowed, and bent cephalad, with approximately two subapical processes and one apical process. Pygofer with lateral angles subacute to rounded, medioventral process higher than wide, apex narrowed to obtuse or elongate apex (lateral margins serrate). Gonostyli broad at base, narrowed at middle, expanded apically in a subovate lobe, with a flange of varying shape on inner face. Male anal segment broadly ovate in dorsal view, widest distad of middle, bilaterally symmetrical or nearly so, apical margin slightly reflexed (apical ventral spine absent).</p>
            <p> Plant associations.  Nivcentia christopheri :  Acacia sp. (  Fabaceae ),  Coccoloba uvifera (L.) (  Polygonaceae );  Nivcentia grenadana :  Miconia sp. (  Melastomataceae ),  Inga sp. (  Fabaceae ), “low bushes;”  Nivcentia hewanorrae : “shrubs” (Fennah, 1945a);  Nivcentia pinicolus :  Pinus cubensis Griseb. ,  Pinus tropicalis Morelet (  Pinaceae ). </p>
            <p>Distribution. Antillean (recorded Cuba, Grenada, St. Kitts, St. Lucia, St. Vincent)</p>
            <p> Remarks. In the broad sense,  Nivcentia Holzinger, 2004 , is comprised of small Antillean  Pentastirini that are not  Melanoliarus Fennah, 1945 sensu stricto (Myrie et al., 2023). Unfortunately, many small pentastirines in mainland regions fit that general description, and it is possible that  Nivcentia is not confined to the Antillean region. Here we more fully define  Nivcentia , but the more complete definition offered here may not fully diagnose  Nivcentia from the heterogeneous mainland  Melanoliarus s.l. However, in our investigation of mainland  Pentastirini (as yet incomplete) we have not yet found any mainland taxa that appear to belong in  Nivcentia . </p>
            <p> Based on illustrations in Fennah (1945a),  Nivcentia sensu stricto appears to consist of  N. interrupta (the type species) and  N. christopheri (Fennah, 1945) , with  N. grenadana (Fennah, 1945) and  N. hewanorrae (Fennah, 1945) differing in form of the terminalia from the other two species. However, Fennah illustrated the aedeagal complex of the former two species from ventral view and the latter two from dorsal view, likely obscuring important features in the illustrations. All current members of  Nivcentia have the endophallus rather broadened, directed left (in ventral view), with the apex bent cephalad, but the species differ in form and number of processes on the periandrium and the form of the apex of the endophallus. Fennah did not illustrate the form of the male pygofer from ventral view, which is a useful character for differentiating groups within  Pentastirini (Mead &amp; Kramer, 1982), nor did he illustrate the form of the male anal tube for the species from dorsal view. Examination of type material will be necessary to elucidate the true limits of  Nivcentia . </p>
            <p> Nivcentia is comparable to  Melanoliarus s.s. (Myrie et al., 2023) in its small size, geographic distribution, and the general shape of the endophallus.  Nivcentia is morphologically diagnosable from  Melanoliarus in the shape of the vertex, which is much narrower in  Melanoliarus , the color of the body, which is often much darker in  Melanoliarus , and the veins of the wings, which are pale and covered in setal bases in both genera, but the tubercles are contrastingly dark in  Nivcentia while in  Melanoliarus , they are usually concolorous to the veins and obscure (excepting  Melanoliarus viequensis Caldwell, 1951 ). In the male terminalia, the genera differ greatly. In  Melanoliarus , the ventral periandrium has the sinistral and dextral processes highly reduced to very short, broad, pointed spines as well as a small process directed cephalad at the apex of the periandrium. This contrasts with the elaborated processes of the ventral periandrium in  Nivcentia . These features are in addition to the presence of a ventroapical spine on the anal tube of  Melormenis s.s. (absent in  Nivcentia ). </p>

            <p> Nivcentia pinicolus (Osborn, 1926) ,  comb. nov.</p>
            <p>(Figs. 1–5)</p>
            <p> =  Oliarus pinicolus Osborn, 1926: 355 (original description). </p>
            <p> =  Melanoliarus pinicolus (Osborn, 1926) ; comb. by implication Emeljanov 2001: 122. </p>
            <p>  Type locality.  Herradura , Cuba  . </p>
            <p>Diagnosis. Relatively small reddish-brown pentastirine cixiid with a uniform brown face (bearing two small dark spots on mediolateral margin, close to the ocelli). Forewings clear (in males) with veins bearing prominent setose granulations (females with wings variably marked in clavus, along nodal line, and irregular apical spots). Pygofer in ventral view broad, medioventral lobe ovate with apex rounded, lateral margins scalloped, just over half length of lateral processes; lateral processes angled outwards in ventral view, apices rounded. Periandrium with four elongated processes; sinistral process (in ventral view), shortest, directed sharply right; ventral mediobasal process long and slender, curved right, then left; dextral process long and slender, curved left; dorsal mediobasal process long and slender, leaning to left (from dorsal view). Aedeagal endosoma with two subapical processes and one apical process. Anal tube without ventroapical process.</p>
            <p>Description. Color. Body generally brownish-red with paler carinae (Fig. 1). Head and face uniform reddish-brown with pale yellow carinae. Face (Fig. 1C) with two small black spots on mediolateral margins of frons (close to lateral ocelli). Postclypeus and anteclypeus uniformly colored and unmarked. Wings transparent, with prominent setal bases; males with forewings unmarked except darkened at pterostigma and claval apex; females (Fig. 5) with variably developed markings from wing base along claval fold, along nodal line and irregular spots subapically, particularly along veins. Legs uniform light brown, paler distally. Venter of terminalia pale yellow.</p>
            <p>Structure. Body slightly compressed, length (including wings), males: 5.22 mm (range 5.13–5.30, n=2), females: 5.55 mm.</p>
            <p>Head. Head in dorsal view (Fig. 1D) narrower than pronotum, weakly projected ahead of eyes; in lateral view (Fig. 1B), head compressed and apically rounded with weak inflections at apex of vertex and in front of eye (corresponding with lateral extremes of transverse carinae). In dorsal view, vertex elongate and nearly parallelsided, widest posteriorly, narrowing slightly to anterior margin (median carina not evident); posterior margin triangularly incised, anterior margin concave, forming slight point at fastigium; vertex approximately twice as long as wide (at posterior margin); subapical carinae (of Löcker et al. 2006) meeting near anterior margin of head (defining two lateral, roughly triangular, areolets) with pair of closely appressed carinae extending anteriorly across fastigium, fusing with median carina of frons to form a vase-shaped apical areolet that joins with dorsal areolet of frons (formed by the bifurcate median carina of frons) to bisect the transverse apical carina. In frontal view (Fig. 1C), face narrowly rhomboid, frons narrowest at dorsal margin, expanding ventrad to lower level of antennae before constricting to epistomal suture (widest just above the frontoclypeal suture), median carina distinct, forked dorsad to form median areolet. Frontoclypeal suture strongly arched. Clypeus elongately rhomboid. Median ocellus distinct, lateral ocelli prominent below anterior margin of eye (Fig. 1B). Eyes elongate oval with small emargination above antennae. Antennae short, stout; scape ringlike, pedicle cylindrical, about as high as wide, bearing numerous sensory pits, flagellum bristlelike with bulbous base.</p>
            <p>Thorax. Pronotum very short and tricarinate (Fig. 1D); anterior margin convex, following contours of head; posterior margin broadly triangularly incised; lateral carinae arced laterad to paradiscal region. Mesonotum at midline about 1.6x length of head and pronotum combined, pentacarinate, lateral carinae diverging posteriorly, reaching posterior margin; intermediate sinuate; median carina obsolete at scutellum. Tegulae conspicuous. Hind leg with about three lateral teeth (two larger, one or more smaller), spinulation 6(5+1)-7-7, tarsal spinulation in uniform arched row (lateral spines somewhat larger). Wings (Fig. 1A) held broadly tectiform. Forewing (Fig. 4) with distinct pterostigma, clavus projected beyond midlength with fusion of Pcu+A1 before claval midlength, fork of CuA proximad of fork of RP from ScP+RA (Cell C5 longer than cell C1); vein branching pattern: RA 3-branched (including vein at margin of stigma), RP 2-branched; MP 5-branched, CuA 2-branched.</p>
            <p>Terminalia. Male terminalia (Figs. 2, 3) with broad pygofer; bilaterally symmetrical; medioventral process (Figs. 2D, 3A) much taller than broad, ovate with apex rounded, lateral margins scalloped, just over half length of lateral processes; lateral processes angled outwards in ventral view, apices rounded, broadest at base. Gonostyli (Fig. 3E) exceeding pygofer, expanded distally into subovate lobe (anterior portion hook-like, projected basad). Periandrium narrow with four slender processes; in ventral view sinistral process somewhat short, directed sharply right, pointed (Fig. 2A, Sp); medioventral process (Fig. 2A, Mvp) long and slender, directed caudad, curved left than right in loop-like shape at distal third; dextral process (Fig. 2A, Dp) long and slender, curved left near apex; in dorsal view, periandrium bearing long slender mediodorsal process (Figs. 2A, 2C, Mdp), directed slightly left. Aedeagus (in ventral view) bearing bulbous, left angled endosoma, bearing three processes; an arcuate subapical process (Fig. 2A, EsV) on inner margin superimposed on structure of endosoma leftwards from aedeagal joint (sensu Mead and Kramer 1982); and bearing elongate apical process (Fig 2A, EsA) directed cephalad-right, causing the appearance of an almost complete loop of the endophallus; in dorsal view bearing broad and looping semi-hyaline subapical process (Figs. 2A. 2C, EsD). Anal tube (Figs. 3D, 3F) broad and ovate, slightly concave at apex in dorsal view.</p>
            <p> Plant associations. Osborn (1926: 355) noted that the syntype series was “collected in the clusters of pine needles on the Cuban Pine,” presumably  Pinus cubensis Griseb. A female from Viñales (Fig. 5) was labeled from  Pinus tropicalis Morelet (tropical pine). </p>
            <p>Distribution. Cuba (all recorded specimens from western Cuba – Herradura and Viñales).</p>
            <p> Etymology. The specific name is apparently derived from  Pinus (Latin for pine, the genus of pine), combined with -cola (from Latin, dweller, inhabitant). We regard the specific epithet as a Latin noun, and as such the termination does not change. Also, in cases where a name might be regarded as an adjective or a noun, the Code specifies that it should be treated as a noun (article 31.2.2, ICZN 1999). </p>
            <p> Material examined.  Lectotype (here designated, Fig. 1) male “Herrad / ura Cuba / 3 16 25 // Herbert / Osborn / Collection // OSUC 0179206 ” (OSUC); 10 male syntypes, same data as lectotype (OSUC).  Female specimen (Fig. 5) “E.E.A. de / Cuba, No. / 9342 // Viñales, Cuba / April 15/30, / S.C. Bruner, / Collector. // On trunks of /  Pinus tropic / alis Morie //  Oliarus ♀ / pinicolus / Osborn / det. / F.W. Mead 1967 // UDCC _ TCN 00101472 ” (NCSU). </p>
            <p> Remarks. Here, we place  Oliarus pinicolus Osborn, 1926 in the genus  Nivcentia as  Nivcentia pinicolus ,  comb. nov. based on the general form of the male terminalia, especially based on the form of the three long processes of the ventral periandrium. While  N. pinicolus ,  comb. nov. differs slightly from  Nivcentia s.s. (viz.  N. interrupta and  N. christopheri ) in the form of the aedeagus, it is clearly within the genus concept. The composition of  Nivcentia and the relationship between its species require further investigation. Further sampling of  Pentastirini in the Greater and Lesser Antilles is needed to better understand the generic limits of the tribe in the region. </p>
            <p> We are designating a lectotype (see material examined) to ensure the stability of the species concept of  Nivcentia pinicolus ,  comb. nov. as specified here. </p>
            <p> The recorded species of  Pentastirini from Cuba (Fig. 13) are  Nivcentia pinicolus ,  comb. nov. (Figs. 1–5),  Melanoliarus complectus (Ball, 1902) (Fig. 8),  M. slossoni (Van Duzee, 1912) (Fig. 10), and  Cyclopoliarus atkinsae (Myers, 1928) (Fig. 6), with  M. franciscanus (Stål, 1859) reported in error (Mead &amp; Kramer, 1982).  Nivcentia pinicolus ,  comb. nov. can be readily diagnosed from each of these species; the small size, reddish-brown coloration, and dark tubercles on the wing veins appear to be diagnostic among the Cuban pentsastirine fauna.  Nivcentia pinicolus ,  comb. nov. lacks the ventroapical projection of the anal tube characteristic of  Melanoliarus s.s. (e.g., Myrie et al., 2023, fig. 6A, viz.  M. complectus ) and is much smaller (under 6 mm) than  Cyclopoliarus (over 7 mm) and  M. slossoni (6.1–7.4 mm in Mead &amp; Kramer, 1982). </p>
            <p> Nivcentia pinicolus also exhibits sexual dimorphism with female specimens apparently being much more boldly marked. A female specimen examined from Viñales, Cuba (Fig. 5) has very bold lateral markings and a transverse band at the lower third of the forewings. </p>
            <p> Three additional specimens from the syntype series of  Oliarus pinicolus Osborn were located in the collection at the United States National Museum at the Smithsonian Institution (USNM), one with a red label stating “Type” and the other two specimens with red “ Paratype ” labels. These specimens were not examined in this study leaving their sexes undetermined. Since the lectotype designation was not published, the specimen labelled “Type” is considered a paralectotype along with the other syntype specimens labelled “ Paratype ” at OSUC and USNM. </p>
