Leptostylopsis cristatus  ; Gilmour, 1963:58

Diagnosis. Th e very pronounced crest on the elytral base distinguishes this species from all others in Hispaniola  . Additionally, the setae on the tubercles are partially erect, appearing as small tufts. The arrangement of black maculae on the pronotum is also distinctive (although somewhat similar to L. argentatus  ) as is the combination of very highly elevated anterolateral pronotal tubercles, dark integument, and very elongate ventrite 5 in females.

Redescription. Length: 9.0-12.0 mm; width: 4.0-5.0 mm.

Head: Covered throughout in dense, appressed, yellowish or ochraceous pubescence except for distinct narrow, median line extending from frontoclypeal margin to occiput and short, glabrous frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible. Antenna: covered with dense, appressed, off-white pubescence; annulate at apex and base of most antennomeres. Last antennomere slightly paler at middle, without distinct annulae; mostly of similar coloration to apex of penultimate antennomere. Antennae longer than body in males, typically extending beyond apices by 4-5 antennomeres. In females, antennae shorter, extending beyond elytral apices by about 3-4 antennomeres. In both sexes, last antennomere slightly shorter than penultimate. Antennal scape extending to posterior 1/3 of pronotum. Eye: lower eye lobe about as tall as gena below it; over 2 × height of upper eye lobe; lobes connected by 5-7 rows of ommatidia in most specimens. Upper eye lobes separated by slightly more than greatest width of scape. Mouthparts: frontoclypeal margin with fringe of short pubescence, mostly not extending to base of labrum; clypeus without pubescence except at extreme base. Labrum with dense, mostly appressed, off-white pubescence with 8-10 long, suberect, translucent setae.

Thorax: Pronotum with moderately to strongly protuberant, broadly rounded lateral tubercles with greatest projection slightly behind middle; with pronounced dorsal tubercles of following arrangement: large, partially denuded oval prominence at middle, surrounded by four smaller tubercles (two anterolateral which project more abruptly than others, and two less elevated posterolateral). Pronotum with moderate

anteromedial elevation at margin; mostly covered in appressed, ochraceous pubescence on very dark brown integument, slight greenish hue; glabrous maculae arranged as follows: mostly complete longitudinal median line from anterior margin across middle callus to base of scutellum; longitudinal line extending from anterior margin to lateral edge of anterolateral tubercles, resuming at posterior margin of posterolateral tubercles to posterior margin. Prothorax with black maculae at base, opposite base of humerus. Pronotum with slight constriction before anterior and posterior margins, each (particularly posteriorly) lined with row of separate, large punctures. Additional smaller punctures scattered over pronotal disk, some obscured by pubescence. Prosternum smooth, impunctate, covered with uniform, appressed, white or tawny pubescence. Prosternal process broad between procoxae, about 0.7 × width of procoxa. Scutellum moderately to densely pale ochraceous pubescent (with slight green hue); broadly rounded posteriorly. Mesosternum smooth, impunctate, covered with uniform, appressed, off-white or pale ochraceous pubescence, less dense on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae very broad, widely separating mesocoxae by about 1.5 × width of mesocoxa. Metasternum covered with appressed, off-white or pale ochraceous pubescence, becoming mottled at sides and on the lateral thoracic sclerites. Elytra: covered with combination of mostly appressed, off-white to pale ochraceous and black pubescence with slight green hue probably due to dark brown integument partially visible beneath; rows of tufted tubercles generally along costae and suture. Tubercles at base of elytra prominent, forming pronounced crests with tufts of semierect black and pale ochraceous setae. Humeri moderately projecting, without black macula at base. Epipleuron with vague green hue. Elytral apex subtruncate, with outer apical angle and sutural angle equally produced. Legs: covered with mostly uniform, appressed, white, off-white, and pale ochraceous pubescence, somewhat mottled; apex and middle of tibiae somewhat annulate due to less dense pubescence exposing darker integument. Middle and hind tibiae slightly longer than femora; hind legs much longer than forelegs; metafemora extending to base of ventrite 5 in females; to just before abdominal apex in males. Tarsi with less dense pubescence than most of legs; appearing darker.

Abdomen: Ventrites covered with appressed, off-white to pale ochraceous pubescence, becoming splotchy at sides. Fifth ventrite only 1.3 × as broad as long in females, narrowed and strongly extended at middle, with or without partial glabrous midline at base.

Distribution. Endemic to Hispaniola  , this uncommon species is recorded from many localities in the Dominican Republic ( Map 3View Maps 3-4).

Remarks. Th is species has been collected under bark, at ultraviolet light, and by general day collecting from April through August.
