Habitus, ventral view; C. Habitus, dorsal view; D. Metasoma, dorsal view. Scale bars: 2 mm. Diagnosis. Exallopyga guatemalensis (Cameron) is easily distinguished from other species in the genus based on the following combination of characters: dark purple bands on dorsum of meso- and metasoma (absent in E. difficilis ); female S3 green or blue (black or non-metallic dark brown in E. jenseni ); lateral ocelli partially encircled by small carina (absent in E. difficilis ); females with emarginate T3 distal rim (with distinct medial notch in E. jenseni ); and the relatively large-sized body, with specimens 7–10 mm long ( E. difficilis : 5–7 mm ; and E. jenseni : 5 mm ). Additionally, according to French (1985) , the spinose lobe of aedeagus in E. guatemalensis is enlarged, reaching almost halfway to the tip of the aedeagus (reaching at most about one third the distance in E. difficilis and E. jenseni ; see his Figures 7–9 ).

Host. Unknown. Remarks. This is the most widely distributed species in the genus, ranging from Guatemala to southern South America. We herein expand its geographical distribution by including new records from the following Brazilian states: Amapá, Amazonas, Bahia, Distrito Federal, Maranhão, Minas Gerais, and Paraíba ( Fig. 5 ). Exallopyga difficilis (Spinola) occurs in Chile through the Andes, reaching southwest Argentina ; and E. jenseni (du Buysson) is only known from northern Argentina to southern Bolivia ( French 1985 ).
