description: <i>Leptostylopsis thomasi</i> Lingafelter &amp; Micheli, sp. n. urn:lsid:zoobank.org:act: 0032FC94-2797-4C44-9721-794574141BBA Map 12, Figs 14, 27, 42, 57, 72, 86, 101, 116 <b>Diagnosis</b>. Th is species is most similar to <i>L. viridicomus</i>, but is recognized by the bold, undulating, transverse white macula on the apical 1/4 of the elytra. Th e sparse, white pubescence with a greenish tinge (less iridescent green than in <i>L. viridicomus</i>) over much of the head, pronotum, and elytra is also distinctive. Other distinctive characters include the short pronotum with subacute lateral tubercles and the narrowly rounded to subacute scutellum. <b>Description.</b> Length: 7.0-11.0 mm; width: 3.0-4.0 mm. <i>Head</i>: Covered throughout in dense, appressed, mottled off-white or pale ochraceous pubescence with slight greenish tinge. Small patch of iridescent green pubescence at middle of head between lower eye lobes in most specimens. Narrow, medianfrontal line from fronto-clypeal margin to between lower eye lobes, continuing along vertex. Short, glabrous frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible. <i>Antenna</i>: covered with dense, appressed, mottled white, off-white, and dark brown pubescence; dark annulate at apex and base of most antennomeres. Last antennomere uniformly dark in most specimens, without annulae, similar in color to apex of penultimate antennomere. Antennae longer than body in both sexes, typically extending beyond elytral apices by 4-5 antennomeres. Last antennomere slightly shorter than penultimate. Antennal scape extending to near posterior margin of pronotum. <i>Eye</i>: lower eye lobe about 0.9 × as tall as gena below it; over 2 × height of upper eye lobe; lobes connected by 4-6 rows of ommatidia in most specimens. Upper eye lobes separated by about greatest width of scape. <i>Mouthparts</i>: frontoclypeal margin with fringe of short off-white pubescence extending about halfway to base of labrum (but longer at sides); clypeus without pubescence except at extreme base. Labrum covered with dense, short white or off-white pubescence with 8-10 long, suberect, translucent setae. <i>Thorax</i>: Pronotum with very protuberant, subacute lateral tubercles with greatest projection at or slightly behind middle; weakly raised dorsal tubercles of following arrangement: large oval prominence at middle, slightly denuded of pubescence, surrounded by four smaller tubercles (two anterolateral and two posterolateral). Pronotum with slight anteromedial elevation at margin. Pronotum mostly covered in appressed, white or off-white pubescence with a greenish tinge. Black maculae present in following pattern: on anterolateral pronotal edge; on posterior margin at middle; at sides opposite elytral humeral base; halfway between middle and lateral posterior maculae. Pronotum slightly constricted before anterior and posterior margins; constrictions (particularly posteriorly) lined with row of separate, large punctures. Smaller punctures scattered over pronotal disk, some obscured by pubescence. Prosternum smooth, impunctate, covered with uniform, appressed, offwhite pubescence with greenish tinge. Prosternal process relatively narrow between procoxae, slightly less than 2/3 width of procoxa. Scutellum dark reddish-brown with sparse off-white pubescence with greenish tinge in most specimens; narrowly rounded posteriorly to subtriangular. Mesosternum smooth, impunctate, covered with uniform, appressed, off-white pubescence with greenish tinge, less dense on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae relatively narrow, separating mesocoxae by slightly less than width of mesocoxa. Metasternum covered with appressed, off-white to slightly iridescent green pubescence, becoming mottled at sides and lateral thoracic sclerites. <i>Elytra</i>: mostly sparsely covered with pale white or translucent pubescence with a green tinge; much of reddish-brown integument exposed. Bold, undulating transverse macula of dense, white pubescence at apical 1/3, partially bordered posteriorly by black macula, two indistinct off-white or ochraceous maculae immediately behind. Rows of small tubercles with tufts of semierect, black pubescence present along costae. Tubercles at base of elytra most prominent, forming weak crests. Humeri projecting slightly, marked at anterior margin with black macula that corresponds to small black macula on prothorax. Epipleuron with vague iridescent pale green pubescence anteriorly, white pubescence posteriorly. Elytral apex subtruncate, with outer apical angle more produced than sutural angle. <i>Legs</i>: mostly uniformly pubescent with appressed hairs (some combination of white, off-white, iridescent green), somewhat mottled; apex and basal 1/3 of tibiae annulate due to less dense pubescence exposing darker integument. Tibiae approximately equal in length to femora; hind legs much longer than forelegs; metafemora extending to middle of ventrite 5. Tarsi dark, with sparse pubescence. <i>Abdomen</i>: Ventrites covered with appressed, white, tawny, or iridescent green pubescence (or some combination), becoming splotchy at sides. Fifth ventrite of females about 2.3 × broader than long, narrowed and extended at middle, with a glabrous midline at base, extending toward apex for 1/3 or more of overall length. <b>Distribution</b>. Th is species is known only from the Sierra de Baoruco range in the Barahona Peninsula of the Dominican Republic and the corresponding range, called the Massif de la Selle, in southeast Haiti (Map 12). <b>Remarks</b>. Th is rare species has been collected only above 1000 m from May through August by beating and at lights. <b>Etymology</b>. Th is species is named for Michael Th omas (FSCA) who collected part of the type series. <b>Type material:</b> <b>Holotype</b> (female): <b>DOMINICAN REPUBLIC: Pedernales Prov</b>., Parque Nacional Sierra de Baoruco, Las Abejas, 1150 m, 18°09.011’N, 71°37.342’W, beating, 17 July 2006, S.W.
