Leptostylopsis argentatus ; Dillon, 1956:145

Diagnosis. Th e small, isolated yellowish maculae on the elytra combined with the transverse postmedial black macula, and longitudinal median black pronotal line distinguish this species. In older, worn specimens, much of the pubescence may be rubbed from the elytra, making identification difficult, but there usually are a few small yellow spots still evident.

Redescription. Length: 7.0-12.0 mm; width: 3.0-5.0 mm.

Head: Covered throughout in dense, appressed, mottled white or off-white pubescence. Mostly obscured narrow, median-frontal line extending from fronto-clypeal margin to between lower eye lobes, continuing in most specimens as median-vertex line between upper eye lobes to occiput. Short, glabrous frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible. Antenna: covered with dense, appressed, mottled white and tawny pubescence; annulate at apex and base of most antennomeres. Terminal antennomere uniformly dark, without annulae, similar in color to apex of penultimate antennomere. Antennae longer than body in males, extending by 4-5 antennomeres beyond elytral apices. Antennae shorter in females, extending by 3-4 antennomeres beyond elytral apices. In both sexes, last antennomere subequal to penultimate. Antennal scape extending to posterior 1/4 of pronotum. Eye: lower eye lobe about 3/4 height of gena below it; over 2 × height of upper eye lobe; lobes connected by 6-8 rows of ommatidia. Upper eye lobes separated by slightly more than greatest width of scape. Mouthparts: frontoclypeal margin with fringe of short pubescence extending beyond base of labrum; clypeus without pubescence except at extreme base. Labrum coated with dense, mostly appressed, white or off-white pubescence with 8-10 long, suberect, translucent setae.

Thorax: Pronotum with weakly to moderately protuberant, broadly rounded lateral tubercles with greatest projection slightly behind middle; with moderately raised dorsal tubercles with following arrangement: large oval, partially denuded prominence at middle, surrounded by four smaller prominences (two anterolateral and two posterolateral). Pronotum with partially glabrous, slight anteromedial elevation at margin. Pronotum mostly covered in appressed, white or off-white pubescence; incompletely glabrous longitudinal medial line present from middle tubercle to base of scutellum, continuing between anterolateral tubercles to pronotal margin at middle. Short, glabrous, black line on outside edge of anterolateral calli, angling to anterior pronotal margin. Pronotum with moderate constrictions before anterior and posterior margins, each lined with row of separate, large punctures (the largest along posterior margin). Additional smaller punctures scattered over pronotal disk, around dorsal tubercles, some obscured by pubescence. Prosternum smooth, impunctate, covered with uni- form, appressed, white or tawny pubescence. Prosternal process broad between procoxae, about as wide as procoxa. Scutellum moderately to densely white pubescent (occasionally with yellow pubescence at apex); broadly rounded posteriorly. Mesosternum smooth, impunctate, covered with uniform, appressed, white pubescence, less dense on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae very broad, separating mesocoxae by about 1.5 × width of mesocoxa. Metasternum covered with appressed, white pubescence, becoming mottled at sides and on the lateral thoracic sclerites. Elytra: covered with combination of mostly appressed, white pubescence with small raised spots of yellow setae scattered throughout and a few spots of black setae along suture at middle 1/3 and in a short, transverse macula postmedially, starting at suture and extending laterad to about 1/4 to 1/3 of elytral width. Elytra with rows of small tubercles generally following along costae. Tubercles at base of elytra most prominent. Humeri projecting slightly. Epipleuron subvertical, not well demarcated dorsally. Elytral apex subtruncate, with outer apical angle more produced than sutural angle. Legs: mostly uniformly pubescent with appressed, white hairs, 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 about abdominal apex. Tarsi generally covered with short, appressed, pale pubescence, with exception of mostly glabrous, dark fifth tarsomere.

Abdomen: Ventrites covered with appressed, white, pubescence, becoming splotchy at sides. Fifth ventrite about 2.5 × broader than long in females, narrowed and extended at middle, with glabrous midline at base, extending toward apex for 1/3 or more of overall length.

Distribution. Th is widespread species is known from southeast Florida, Cuba, Puerto Rico, Bahamas, southeastern Haiti, and throughout the Dominican Republic ( Map 2 View Maps 1-2 ). Haiti and the Dominican Republic may represent new country records as this species was not recorded from either country by Perez-Gelabert (2008) or Monné and Bezark (2009) (but was recorded from “ Hispaniola ” in Monné 2005).

Remarks. Th is species has been collected from May through August at lights, from dead logs, and by beating dead vegetation at night.
