NOV. Material examined: Holotype . Male. Peru : Madre de Dios . Río Tambopata Reserved Zone , 30 km SW Puerto Maldonado , 290 m , 6.ix.1984 , T. L. Erwin et al. ( SI ). Etymology: The specific epithet is taken from the type locality of this species. Description: Male . Head . Mostly brown; narrow white band between vertical and orbital markings; coronal suture black; frontal suture bordered with brown band; frons with two pairs of white spots, median pair smaller and located dorsally, lateral pair large, extending from dorsal margin of postclypeus to frontal suture; gena white; eye black, small, interocular space/eye-diameter ratio (IO/D) = 1.6; ocelli white, ocellar field black; antennal socket bordered with brown band; postclypeus white with T-shaped blackish brown marking on ventral half, dorsal region with c . six rows of pale brown spots; anteclypeus pale brown. Antenna pale brown. Mouth parts pale brown; 4th segment of maxillary palpus dark brown. Thorax . Prothorax brown. Mesonotum brown, with white spot posterior to anterior lobe of scutum, lateral lobe of scutum with transversal narrow white line; scutellum blackish brown; postnotum pale brown. Metanotum brown, with white spot at posterior end of anterior lobe of scutum; scutellum blackish brown; postnotum brown. Meso- and metapleurites brown except membranous region white. Legs. Coxae brown; middle leg pale brown, tibia darker; fore and hind legs missing. Forewing ( Fig. 1C ). Spots in cell a 1 not separated. Opposing spots in cell r absent, but similar markings, not homologous, in posterior region of cell r just proximal to proximal band. Proximal band reduced, interrupted beyond CuP and almost absent between M-CuA fork and basal section of Rs. Median spots almost absent except for some faint markings along discoidal veins. Distal band almost indistinct except for brown spot in cell r 3 . Spot on roof of cell m 3 small, only distinct below distal Ms-CuA fork. Submarginal spots reduced, spots in cell r 1 and m 3 hardly visible. Marginal clouds almost indistinct except for brown spots on distal ends of vein R 2+3 , R 4+5 and M 1 . Hindwing. Hyaline; veins brown. Abdomen . White, with sparse minute brown spots. Terminalia . Epiproct lobe ( Fig. 2E, F ) expanded antero-dorsally, smoothly rounded, medially with longitudinal swelling. Paraproct ( Fig. 2E ): ventro-lateral band absent; distal process short, directed posteriorly. Hypandrium ( Fig. 2G ) with wide membranous region on left side; left process well projected, arched inwardly, cylindrical; right side of hypandrium with lobe-like projection (= right process), lobe with broad membranous region near right edge, external edge of lobe covered by denticles. Phallosome ( Fig. 2H ) nearly symmetrical, only slightly left-skewed posteriorly, posterior margin wide, with papillae, postero-lateral corner with projection. Phallobase narrowing apically, with pair of projections directed anteriorly. Key to species of the roesteri group 1.
