Epropetes tristis sp. nov.

( Fig. 9 )

Head black. Frons and vertex punctate. Eyes almost divided; upper ocular lobes narrow, distance between them equal to six times the width of one lobe. Antennae yellowish-brown (broken at the apex of antennomere VII). Scape (length, 1.0 mm), slightly shorter than antennomere III (length, 1.2 mm). Pedicel elongate. Antennomere III with long hairs, moderately dense on inner side.

Prothorax black, longer than wide and strongly constricted at base. Pronotum densely punctate, with long white hairs throughout. Prothorax finely punctate laterally. Prosternum smooth on anterior third, finely rugose toward the sides of the anterior margin and posterior third punctate.

Elytra black, except for a small triangular yellow spot on sides at anterior third; a broad band of white pilosity covering much of anterior third, (easily visible depending on incidence of light); behind this pubescent band is a black integumental band of similar size followed by the apical third covered in white pubescence. Elytral apices rounded.

Femora and tibiae black; tarsi reddish-brown. Underside of body black. Urosternites narrower toward abdominal apex; urosternite V very narrow.

Measurements, in mm, holotype (female?). Total length, 10.3; prothorax length, 2.0; greatest width of prothorax, 2.0; elytron length, 7.5; humeral width, 2.5.

Type material. Holotype (female?), PANAMA, Darien: Cerro Chucanti (850 m), 13–16.II.2012, L. G. Bezark col. ( CLBS).

Etymology. Latin, tristis = sad; alluding the color of integument.

Discussion. Epropetes tristis sp. nov. is similar to E. velutina Martins, 1975 . It differs: by the more elongate slender prothorax, giving a more elongate appearance; by the black elytral band, situated below the anterior white band, without red pubescence; by the absence of white, pubescent spots on ventral surface. In E. velutina : part of the prothorax is globular; elytral black band, situated behind the white band is oblique; metepisterna and the sides of the metasternum with red pubescence intermixed with white, shining pubescence.
