Diagnosis. Th is species can be confused only with L. viridicomus  , but L. chlorescens  has even more pronounced iridescent green pubescence over most of the integument. The dorsal tubercles (in particular the median and anterolaterals) are more highly elevated in L. chlorescens  than in L. viridicomus  . Th e apex of the elytron in L. chlorescens  has a distinctive white macula that has anteriorly directed, fingerlike extensions.

Description. Length: 8.0- 12.5 mm; width: 3.0-5.0 mm.

Head: Covered throughout in dense, appressed, iridescent green pubescence with some ochraceous setae along frontoclypeal and eye margins. Partially obscured, narrow, median-frontal line, continuing on vertex; short, glabrous frontal-genal line extending from anterior tentorial pits along anterior margin of genae to base of mandible. Antenna: covered with mottled white to off-white and dark, translucent pubescence; dark annulate at apex and base of most antennomeres. Last antennomere mostly dark, with paler hairs at middle in some specimens. Antennae longer than body in both males and females, typically extending beyond elytral apices by 4-5 antennomeres. In both sexes, last antennomere slightly shorter than penultimate. Antennal scape extending to posterior 1/4 of pronotum. Eye: lower eye lobe subequal in height to 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 about greatest width of scape. Mouthparts: frontoclypeal margin with sparse fringe of short pubescence extending to about base of labrum; clypeus without pubescence except at extreme base. Labrum with sparse white or off-white pubescence with 8-10 longer, suberect, translucent setae.

Thorax: Pronotum with prominent, narrowly rounded to subacute lateral tubercles with greatest projection slightly behind middle; mostly prominently raised dorsal tubercles with following arrangement: very large, partially denuded, highly projecting oval tubercle at middle, two smaller but as highly elevated anterolateral tubercles (sometimes partially denuded), and two weakly elevated posterolateral tubercles. Pronotum with slight anteromedial elevation at margin. Pronotum mostly covered in appressed, iridescent green pubescence but with very small, indistinct patches of dark brown to black pubescence in following arrangement: at basal margin, on each side between antero- and posterolateral tubercles, and at anterior margin on each side in front of anterolateral tubercles. Pronotum with slight constriction 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, off-white or pale ochraceous pubescence. Prosternal process moderately broad between procoxae, slightly less than 2/3 width of procoxa. Scutellum moderately pubescent with iridescent green setae at middle and dark brown to black setae on lateral margins (and adjacent elytra); subtriangular, narrowly rounded to subacute posteriorly. Mesosternum smooth, impunctate, covered with uniform, appressed, off-white or pale ochraceous pubescence, unlike most species, equally dense

on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae broad, separating mesocoxae by about width of mesocoxa. Metasternum and lateral thoracic sclerites covered with appressed, mottled off-white or pale ochraceous and iridescent green pubescence. Elytra: covered with appressed, mostly iridescent green pubescence with very small, scattered white and ochraceous pubescent patches particularly along suture, apical margin, and atop costal tubercles. Black pubescence on some elytral tubercles, along margins near scutellum, and in small apicolateral macula. White pubescence forming small apical macula with three elongate fingerlike projections directed anteriorly along costae. Tubercles at base of elytra most prominent, forming moderate crests. Humeri moderately projecting, anterior margin lacking black macula. Epipleuron with pronounced iridescent green pubescence. Elytral apex subtruncate, with outer apical angle more produced posteriorly than sutural angle. Legs: mostly uniformly pubescent with combination of appressed, iridescent green and white pubescence, somewhat mottled; middle and base of tibiae with incomplete annulae of white pubescence. Tibiae approximately equal in length to femora; hind legs much longer than forelegs; metafemora extending to about abdominal apex. Tarsi sparsely coated with short, appressed, white or pale green pubescence; apices not appreciably darker than bases.

Abdomen: Ventrites covered with mottled, appressed, off-white or pale ochraceous and iridescent green pubescence. Fifth ventrite of females about 2.4 × 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. Th is very rare species is known only from the Sierra de Baoruco region in southwestern Dominican Republic ( Map 9View Maps 9-10).

Remarks. All three known specimens were collected by beating at a tree fall in July.

Etymology. Th e name is a modified Latin adjective referring to the greenish color of the pubescence over most of the integument.
