Dissomphalus hastatus Evans 1979: 278 , 281–282, Gordh & Moczar 1990: 222, Azevedo 1999c: 924 (designation of synonymy)

This is widespread species in South America ( Azevedo, 1999c), and now it is recorded for the first time to Brazil, Acre and Panama. There are two morphological patterns of genitalia, one with dorsal body of aedeagus with apex slightly sharpened and paramere apex more elongate, and another one with dorsal body of aedeagus with apex not sharpened and paramere apex slightly more robust. Generally, specimens of first pattern have clypeus with small median tooth, and specimens of second pattern have clypeus with long median tooth, but there is broad gradient of tooth size. Both patterns can be founded in the same sites.
