Diagnosis. Th is species is recognized by its very dark reddish-brown integument covered by reddish-brown setae. Additionally, there is a distinctive small, oval, black macula on the epipleuron above the metepisternum. Furthermore, most specimens have

two transverse, black, postmedial elytral maculae, the anterior of which is bordered by white or off-white pubescence.

Description. Length: 7.5-12.0 mm; width: 3.0- 4.5 mm.

Head: Integument very dark reddish-brown, covered throughout in dense, reddishbrown to tawny pubescence. Mostly obscured narrow, median-frontal line present, extending from fronto-clypeal margin, between antennal tubercles, to occiput (occasionally mostly visible). Short, glabrous frontal-genal line present, extending from anterior tentorial pits along anterior margin of genae to base of mandible. Antenna: covered with dense, appressed, mottled white and dark-brown pubescence; dark 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 elytral apices by 3-4 antennomeres. In females, antennae shorter, extending beyond elytral apices by about 2 antennomeres. In both sexes, last antennomere slightly shorter than penultimate. Antennal scape extending to posterior 1/3 or 1/4 of pronotum. Eye: lower eye lobe about as tall as gena below it; over 2 × height of upper eye lobe; lobes connected by 4-6 rows of ommatidia. Upper eye lobes separated by about greatest width of scape. Mouthparts: frontoclypeal margin with fringe of short pubescence extending to about base of labrum (with longer setae at sides); 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: Integument very dark reddish-brown. Pronotum with moderately protuberant, rounded lateral tubercles with greatest projection at middle; with moderately raised dorsal tubercles of following arrangement: large, partially denuded oval prominence at middle, surrounded by four tubercles (two strongly projecting anterolateral and two weakly projecting posterolateral). Pronotum with slight anteromedial elevation at margin. Pronotum mostly covered in appressed, reddish-brown or tawny pubescence (some specimens with ochraceous and white pubescence also), with indistinct patches of dark brown to black pubescence anteriorly at margin in front of anterolateral tubercles, posterior to posterolateral tubercles, laterally, opposite of humeral base, and at posterolateral margins on each side of pronotal disk. Pronotum with slight constriction before anterior and posterior margins, constrictions (particularly posteriorly) lined with row of separate, large punctures. Many additional smaller punctures scattered over pronotal disk, mostly free of pubescence. Prosternum smooth, impunctate, covered with uniform, appressed, white or very pale ochraceous pubescence. Prosternal process broad between procoxae, about 3/4 width of procoxa. Scutellum very dark, moderately to densely reddish-brown pubescent; broadly rounded posteriorly. Mesosternum smooth, impunctate, covered with uniform, appressed, white or off-white pubescence, less dense on anterior 1/3 which is deeply constricted. Mesosternal process between mesocoxae broad, separating mesocoxae by about 1.2 × width of mesocoxa. Metasternum covered with appressed, white or off-white pubescence, becoming mottled at sides and on the lateral thoracic sclerites. Elytra: Integument very dark reddish-brown, covered with combination of mostly appressed, reddish-brown pubescence, but with numerous white, ochraceous, and black setae. Pattern typically with two incomplete transverse black maculae at posterior 1/2: one postmedially (bordered anteriorly by white pubescence), the other at apical 1/4 (not present in all specimens). Rows of small tubercles with tufts of black semi-erect setae present along costae and suture. Tubercles at base of elytra most prominent, forming weak crests. Humeri strongly projecting, partially denud- ed dorsally, marked at anterior margin with black macula corresponding to lateral black macula on prothorax. Epipleuron covered with reddish-brown pubescence and small, oval, black macula above metepisternum. Elytral apex subtruncate, with outer apical angle slightly produced posteriorly. Legs: mostly uniformly pubescent with appressed, tawny hairs, somewhat mottled; basal 1/3 and postmedial part of tibiae with partial annula of mottled white pubescence. Tibiae approximately equal in length to femora; hind legs much longer than forelegs; metafemora extending to beyond base of ventrite 5. Tarsi generally coated with short, appressed, white or off-white pubescence; apices of tarsomeres with less pubescence, darker.

Abdomen: Ventrites very dark reddish-brown, covered with appressed, white or off-white pubescence, becoming more splotchy at sides. Fifth ventrite of females 1.3 × broader than long, narrowed and greatly extended at middle, with inconspicuous glabrous midline at base, extending toward apex for about 1/5 of overall length.

Distribution. Endemic to Hispaniola , this species is known from the Cordillera Central, Sierra de Neiba, and Sierra de Baoruco in the Dominican Republic, and extreme southeast Haiti ( Map 8 ).

Remarks. This species has been collected from May through September by blacklighting, beating, and hand collecting from the endemic Hispaniolan pine, Pinus occidentalis .

Etymology. Th e name is a Latin adjective referring to the overall dark color of the body.
