( Figs. 15–20 )

Holotype male, Panama, Colon province, Pipeline Road , 20.vi.1982, H. P. Stockwell col. (STRI_ENT_0063017).

Description. Holotype male. Integument mostly dark brown, nearly black on some areas; frons (except dark brown area under antennal tubercles), genae, and prothoracic tubercles reddish brown; mouthparts, coxae, and base and ventral surface of femora light brown; antennomere IV light brown, dark brown toward apex; gulamentum yellowish; prothorax reddish brown except lateral tubercles, which are light brown; pronotum orangish with a central black band. Scutellum dark brown. Elytra with anterior half orangish except blackish wide longitudinal band close to suture and lateral margin.

Head. Frons transverse, slightly convex anteriorly; finely punctate, with yellowish pubescence covering surface, pubescence denser laterally and close to median groove, which is deep, narrow and reaching clypeus. Eyes deeply emarginate; distance between upper eye lobes 0.3 times distance between outer margins of eyes; frontally, distance between lower eye lobes 0.6 times distance between outer margins of eyes. Area between upper eye lobe and base of antenna with yellowish pubescence. Genae 1.3 times longer than lower eye lobe. Gulamentum smooth and glabrous. Dorsal sides of occiput with a patch of yellowish pubescence not obscuring integument. Surface of antennal tubercles with sparse grayish pubescence not obscuring integument. Antennae slender, reaching elytral apices at base of antennomere VIII, finely punctate; scape elongated and cylindrical, slightly expanded apically, reaching mesocoxae in lateral view; with long black setae ventrally, antennomere III with moderately long black setae ventrally; IV slightly longer than V; V–XI each similar in size and pubescence. Antennal formula based on length of antennomere III: –Scape = 1.57;—Pedicel = 0.08;—IV = 0.97;—V = 0.82;—VI = 0.80;—VII = 0.82;— VIII = 0.91;—IX = 1.00;—X = 1.10;—XI = 0.60.

Thorax. Prothorax 1.2 times wider than long; lateral tubercles short and acute, with a shallow dorsal depression basally. Pronotum moderately convex anteriorly, depressed posteriorly; finely punctate, punctures more abundant and coarser posteriorly. Prosternum with moderately dense pale setae; prosternal process narrow, not laminiform, expanded apically, narrowest area 0.22 times procoxal width; mesanepisternum and mesepimeron with sparse grayish pubescence not obscuring integument; mesoventral process truncate apically, narrowest area 0.1 times mesocoxal width; metanepisternum with sparse grayish pubescence not obscuring integument; meso and metaventrites with sparse grayish pubescence not obscuring the integument; metathoracic discrimen complete.

Elytra. Abundantly, coarsely, punctate; apex emarginate, sinuous toward rounded sutural angle, outer angle spiniform;with long,erect,sparse black setae throughout.On elytral anterior half, integument obscured by dense orangish pubescence, centroapical area and suture covered with sparse grayish pubescence, not obscuring integument.

Legs. With abundant yellowish pubescence not obscuring integument; mesotibiae with short, erect black setae from basal quarter ventrally and from middle dorsally, setae distinctly denser about posterior third, metatibiae with short, erect, black setae from basal quarter ventrally and from base dorsally to posterior third. Metatarsomere I slightly longer than twice length of II–III together.

Abdomen. Ventrites with grayish pubescence not obscuring integument; intersegment of ventrites 1 and 2 with yellowish pubescence; apex of ventrite 5 concave.
