Material examined: Ecuador: Napo, 1 km S Oncone Gare Camp, Waorani Ethnic Reserve , 220 m, 0°39′10″S, 76°26′W, 8.ii.1995 ( SI) , 1 male, T. L. Erwin et al. (950) ( SI) ; 1 male, same data (968) ( SI) ; 1 male, same locality and collector, 10.ii.1995 (993) ( SI) ; 1 male, same locality and collector, 11.ii.1995 (1022) ( SI) ; 2 females (abdomen missing), same locality and collector, 12.ii.1995 (1041) ( SI) . Peru: Madre de Dios, Río Tambopata Reserved Zone , 30 km SW Puerto Maldonado, 12°50′S, 69°17′W, 16.ix.1984 , 1 female, T. L. Erwin et al. ( SI) .

Description of the male terminalia: As for the group diagnosis. Epiproct lobe ( Fig. 2B ) expanded dorsally, bilobed. Paraproct ( Fig. 2A ); ventro-lateral band indistinct; distal process long, directed upwards. Hypandrium ( Fig. 2C ) with broad mesal membranous region; left process well developed, lamellate, triangular; right side of hypandrium with complicated lobe-like projection (= right process), lobe with membranous region, external surface of lobe covered basally by denticles. Phallosome ( Fig. 2D ): Slightly skewed to left, posterior margin broad, truncated and with papillae, postero-lateral corner with extended process. Phallobase narrowing to somewhat truncated anterior end.

Remarks: This species has been known from the type specimen (sex unknown) and females re-described by Mockford (1991). Examined specimens match the forewing markings of the original description and also the female genital structures in Mockford’s re-description.

Distribution: Ecuador, Peru, Brazil, Argentina.
