Dorsal color black, except head, anterolateral angles of pronotum and apical margin of elytra yellow; ventral color black, except legs, antennae, mouthparts and last three ventrites yellow. Males with first ventrite unmodified; fifth ventrite with nearly straight posterior margin, only slightly emarginate; sixth ventrite emarginate, depressed, with conspicuous lateral angles. Male genitalia with penis guide wide, apically acute ( Fig. 11 ); parameres wide; penis robust ( Fig. 12 ).

Distribution: South America ( Gordon 2000; González 2015). New record for Mexico.
