( Figs. 21–25 )

Holotype female, Panama, Panama province, Cerro Campana , 26.xi.1977, H. P. Stockwell (STRI_ENT_0063016).

Description. Holotype male. Integument mostly dark brown; head, gulamentum, mouthparts, and apex of tarsal claws reddish brown; maxillary and labial palpi and antennomere IV yellowish, dark brown toward apex; peduncle of pro- and mesofemora and base of tarsal claws light-brown; prothorax reddish brown dorsally, dark brown ventrally; pronotum orangish with wide longitudinal dark-brown area centrally. Scutellum dark brown. Elytra with anterior 2/3 orangish except brownish wide longitudinal band close to suture.

Head. Frons transverse, slightly convex anteriorly, finely punctate with yellowish pubescence not obscuring integument; area between antennal tubercles with wide yellowish pubescent band on each side of median groove; 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; space between upper eye lobe and base of antenna with yellowish pubescence. Genae 0.75 times shorter than lower eye lobe. Central area of postclypeus with a pair of short, erect black setae, and one long, erect black seta on each side; sides of postclypeus with one short erect black setae. Anterior margin of labrum with short yellow setae. Gulamentum smooth and glabrous. Antennae slender, reaching elytral apex at base of antennomere VI; finely punctate, dorsally covered with grayish pubescence not obscuring integument; scape elongated and cylindrical, slightly expanded apically, reaching mesocoxae in lateral view; scape and antennomere III with long erect black setae ventrally; antennomere IV with sparse, long, erect black setae ventrally; antennomeres V–VI with black setae apically. Antennal formula based on length of antennomere III:—Scape = 1.20;—Pedicel = 0.07;—IV = 0.87;—V = 0.72;—VI = 0.47;—VII = 0.30;—VIII = 0.70;—IX = 0.27;—X = 0.12;—XI = 0.20.

Thorax. Prothorax 0.75 times wider than long, lateral tubercles feebly developed, obtuse. Pronotum moderately convex on disc, depressed posteriorly; with sparse whitish pubescence; finely punctate, punctures abundant, coarser posteriorly. Prosternum with grayish pubescence not obscuring integument; prosternal process narrow, not laminiform, expanded apically, centrally 0.2 times procoxal width. Mesanepisternum and mesepimeron with sparse grayish pubescence not obscuring integument; mesoventral process narrow, not laminiform, centrally 0.16 times mesocoxal width; metanepisternum with sparse grayish pubescence; meso and metaventrite with sparse grayish pubescence not obscuring the integument; metathoracic discrimen reaching middle of metaventrite.

Elytra. Coarsely punctate on anterior half and laterally on anterior fifth, punctures gradually sparser toward posterior region; light area with dense orangish pubescence and dark area with sparse grayish pubescence, except area close to suture on anterior 2/3 with orangish pubescence partially obscuring integument; with abundant, long, erect dark setae; humeral carina feebly marked, extending from humeri to beginning of posterior third; apex emarginate, sutural and outer angle feebly acute.

Legs. Covered with grayish pubescence not obscuring integument; meso- and metatibiae with a few long, erect black setae from basal quarter ventrally and from middle dorsally. Protibiae curved, armed with one pre-medial rounded tubercle. Protarsomere I about as long as II–III together; meso- and metatarsomere I twice length of II–III together.

Abdomen. Ventral surface with grayish pubescence not obscuring integument. Ventrite 5 not extending beyond elytral apices, sides and apex rounded.
