Dissomphalus curvilongus Azevedo, 2001

Dissomphalus curvilongus Azevedo, 2001: 354 –355 (♂, holotype from Brazil).

Diagnosis. Male. Black. Mandible with two apical teeth. Median clypeal lobe trapezoidal. Frons strongly coriaceous. Genitalia: volsella with long apical tooth; aedeagal ventral ramus as long as dorsal body, laminar, surface subhorizontal, wide, apex converging, bidentate; aedeagal dorsal body with two pairs apical lobes, outer pair divided in 2 rami, dorsal ramus laminar, progressively thinner, outer margin conspicuously serrated, apical area setose serrated, ventral ramus thin, not serrated; inner pair membranous, stout, inner surface setose; basal process with median tooth, pair of lateral expansions somewhat wide, long, more than 0.5 × Length paramere, curved downward, nearly reaching ramus aedeagus, setose serrated.

Variations. The main variation found in this series is the development of the aedeagal basal process, which can be longer than the apical lobes, equally as long, or shorter than the apical lobes.

Remarks. This species was previously known from Trinidad & Tobago and Brazil (Amapá, Amazonas, Pará, Acre, Rondônia, Ceará and Maranhão) ( Azevedo 2001). Now it is recorded for the first time from Piauí and one more male was found in Maranhão.
