Leptostylus viridicomus Fisher, 1942:29 

Diagnosis. Th is species is similar to L. milleri  and L. chlorescens  of Hispaniola  due to the abundance of iridescent green pubescence. Leptostylopsis viridicomus  is distinguished from L. chlorescens  by the presence of a lateral black macula on the prothorax adjacent to the elytral humeral base. Leptostylopsis viridicomus  lacks the subhumeral black macula on the elytra present in L. milleri  .

Redescription. Length: 8.0-13.0 mm; width: 3.5-4.5 mm.

Head: Covered in dense, appressed, mottled, vaguely green and pale ochraceous pubescence (with slight iridescent green sheen between antennal tubercles in some specimens). Narrow median-frontal line extending from frontoclypeal margin between antennal tubercles and on vertex to at least between upper eye lobes, sometimes further toward 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 off-white and translucent pubescence; annulate at apex and base of most antennomeres. Last antennomere uniformly dark, without annulae, similar in color 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 shorter than penultimate. Antennal scape extending to posterior 1/3 or 1/4 of pronotum. Eye: lower eye lobe about 1.2 × taller than 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 little more than greatest width of scape. Mouthparts: frontoclypeal margin with fringe of pubescence extending about 1/2 distance to base of labrum; clypeus without pubescence except at extreme base. Labrum with mostly appressed, off-white pubescence with 8-10 long, suberect, translucent setae.

Thorax: Pronotum with protuberant, weakly acute or narrowly rounded lateral tubercles with greatest projection slightly behind middle; with pronounced, raised dorsal tubercles of following arrangement: oval tubercle at middle, partially denuded of pubescence, surrounded by four tubercles (two anterolateral, raised higher than all others, and two less elevated posterolateral). Pronotum with slight anteromedial elevation at margin. Pronotum mostly covered in appressed pubescence of several colors (off-white, iridescent green, black, and ochre). In some specimens, ochraceous pubescence forming two indistinct anterolateral patches. Small black maculae at anteromedial margin, extending from anterolateral edge of anterolateral tubercles to anterior margin of pronotum, extending from posterior edge of posterolateral tubercles to posterior pronotal margin, and at sides of prothorax, adjacent to humeral base. Pronotum with slight constriction before anterior and moderate constriction before posterior margins; constrictions (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, off-white or greenish pubescence. Prosternal process narrow between procoxae, about 1/2 width of procoxa. Scutellum with mottled off-white or greenish pubescence; rounded posteriorly. Mesosternum smooth, impunctate, covered with uniform, appressed, off-white or greenish pubescence, less dense on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae relatively narrow, separating mesocoxae by about width of mesocoxa. Metasternum covered with appressed, white, offwhite, to slightly pale green pubescence, becoming mottled at sides and on the lateral thoracic sclerites. Elytra: covered with combination of mostly appressed, white, off-white, ochraceous, black, and iridescent green pubescence. Elytral pubescence forming pattern as follows: translucent patch around basal crest giving appearance of vaguely delimited dark brown macula; anterior to this, extending to base of elytra in many specimens, a vaguely defined patch of ochraceous pubescence; narrow, transverse, angled, white macula bordered posteriorly by narrow black macula originating at suture, just behind middle; most of remainder of anterior 2/3 of elytra with iridescent green pubescence interrupted by small, dark pubescent tubercles; at apical 1/4 lies indistinct narrow, angled, transverse, black macula with patch of off-white or pale ochraceous pubescence behind. Rows of small tubercles generally along costae and suture. Tubercles at base of elytra most prominent, forming weak crests. Humeri projecting moderately, without black macula at base. Epipleuron with vague iridescent green pubescence and elongate dark macula, partially visible from above. Elytral apex subtruncate, with outer apical angle more produced posteriorly than sutural angle. Legs: mottled off-white, white, or pale green pubescent with mostly appressed setae; apex of tibiae annulate due to less dense and semi-translucent pubescence exposing darker integument. Incomplete annula at basal 1/3 of tibiae. Tibiae approximately equal in length to femora; hind legs much longer than forelegs; metafemora extending to base of ventrite 5. Tarsi generally coated at base of each tarsomere with short, appressed, off-white or pale green pubescence; apex of tarsomeres darker.

Abdomen: Ventrites covered with appressed, white, off-white, or pale green pubescence, becoming splotchy at sides. Fifth ventrite of females 1.8 × 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.

Distribution. Endemic to Hispaniola  , this species is known from southeastern Haiti and the Sierra Neiba and Cordillera Central regions of central and western Dominican Republic ( Map 6View Maps 5-6).

Remarks. Th is species has been collected at high elevations in cloud forests and mixed pine forests, above 900 m, from May through October by beating, hand-collecting, canopy traps, and in Malaise traps.
