Leptostylopsis milleri ; Gilmour, 1963:59

Diagnosis. Th is species is recognized most easily by the pattern of ochraceous, black, and iridescent green pubescence on the pronotum and elytra. Superficially it is similar to L. viridicomus and L. chlorescens , but those species have more extensive green iridescence. Leptostylopsis milleri also has iridescent green setae between the antennal tubercles, generally more developed than in L. viridicomus . It is further distinguished by its uniformly dark tarsi and by the setae atop the elytral tubercles that tend to be semierect (as in L. viridicomus ) and not appressed as in L. annulipes . It further differs from L. annulipes in lacking distinct ochraceous pubescence patches on the pronotum and elytral base, and differs from L. viridicomus in having a subhumeral black macula which is absent in L. viridicomus .

Redescription. Length: 7-11 mm; width: 3.0-4.0 mm.

Head: Covered throughout in dense, appressed, mottled off-white to pale ochraceous pubescence. Most specimens with small patch of iridescent green pubescence at middle of head between antennal tubercles. Mostly obscured, narrow, median-frontal line present, extending from fronto-clypeal margin to between lower eye lobes (variably developed); short, glabrous frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible, to ventral edge of lower eye lobe in most specimens. Antenna: covered with dense, appressed, mottled off-white and pale ochraceous pubescence; annulate at apex and base of most antennomeres. Last antennomere uniformly dark, without annulae, of similar coloration to apex of penultimate antennomere. Antennae longer than body in males, extending beyond apices by about 4 antennomeres. In females, antennae shorter, but still extending beyond elytral apices by about 3 antennomeres. In both sexes, last antennomere slightly shorter than penultimate. Antennal scape extending to posterior 1/3 of pronotum. Eye: relatively small, lower eye lobe 0.7 × as tall as gena below it; less than 2 × height of upper eye lobe; lobes connected by 4-5 rows of ommatidia in most specimens. Upper eye lobes separated by little less than greatest width of scape. Mouthparts: frontoclypeal margin with inconspicuous fringe of short pubescence extending about halfway to base of labrum; clypeus without pubescence except at extreme base. Labrum with inconspicuous, appressed, off-white or pale ochraceous pubescence with 8-10 long, suberect, translucent setae.

Thorax: Pronotum with moderately protuberant, broadly rounded lateral tubercles with greatest projection slightly behind middle; with moderately raised dorsal tubercles of following arrangement: oval prominence at middle, partially denuded of pubescence, surrounded by four tubercles (two anterolateral and two smaller posterolateral). Pronotum with slight anteromedial elevation at margin. Pronotum mostly covered in appressed, ochraceous and iridescent green pubescence. Black pubescence forming small maculae at middle, opposite base of scutellum, at posterior margin between middle and posterolateral calli, at anterior margin to lateral edge of anterolateral tubercles, and at sides, opposite humeral base. Pronotum with slight constriction before anterior and posterior margins, each (particularly posteriorly) lined with row of separate, large punctures and often with concentration of iridescent, green setae. 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 2/3 width of procoxa. Scutellum moderately to densely ochraceous and iridescent green pubescent; broadly rounded posteriorly. Mesosternum smooth, impunctate, covered with uniform, appressed pubescence, but less dense on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae moderately broad, about as wide as mesocoxa. Metasternum covered with appressed, off-white pubescence (sometimes with slight iridescent green hue), becoming mottled at sides and on lateral thoracic

sclerites. Elytra: covered with combination of mostly appressed, off-white, ochraceous, black, and iridescent green pubescence. Ochraceous pubescence forming two vague, angled maculae near suture at middle and posterior 1/4. Posterior pale macula bordered anteriorly by angled black macula continuing partially toward median pale macula and laterad toward outer elytral margin. Variably developed small, black maculae also present posterior to basal elytral crests. Rows of small, setose tubercles generally following costae. Tubercles at base of elytra most prominent, forming weak crests. Humeri slightly projecting, marked at anterior margin with black macula that corresponds to small black macula on prothorax. Epipleuron with iridescent green pubescence and variably developed elongate, black macula. Elytral apex subtruncate, with outer apical angle more produced posteriorly than sutural angle. Legs: mostly pubescent with mottled, appressed, off-white and pale ochraceous pubescence; apex and basal 1/3 of tibiae vaguely annulate due to less dense and more translucent pubescence exposing darker integument. Tibiae approximately equal in length to femora; hind legs much longer than forelegs; metafemora of moderate length, extending to about base or middle of ventrite 5. Tarsi generally coated with short, appressed pubescence of similar color to apex of tibiae, appearing very dark.

Abdomen: Ventrites covered with appressed, off-white to pale ochraceous pubescence, becoming splotchy at sides. Fifth ventrite about 2 × as broad as long in females, narrowed and extended at middle, with glabrous midline at base, typically extending toward apex for 1/3 or more of overall length.

Distribution. Endemic to Hispaniola , this species occurs throughout the Dominican Republic; it is most abundant in the Barahona Peninsula region ( Map 4 ).

Remarks. Th is species has been collected from May through July at tree falls, at mercury vapor and blacklights, by beating during day and night, and by flight intercept traps.
