Dissomphalus infissus Evans, 1969

Dissomphalus infissus Evans, 1969: 14 , 19, 22 (♂, holotype from Argentina, FIML, figs 14, 20, 28); Gordh & Móczár, 1990: 226; Azevedo, 1999b: 929, 933–934; 2003: 27; Redighieri & Azevedo, 2006: 311, Colombo & Azevedo, 2016: 28 –29.

Diagnosis. Mandible tridentate. Clypeus trapezoidal. Tergal process lateral with elliptical and inclined depressions and linear and oblique tuft of setae. Hypopygium with posterior margin straight. Genitalia: paramere short and wide; apex concave and very produced dorsally; aedeagal ventral very short; base wide; apical half narrow, slightly convergent with apex very sharpened; inner margin sinuous; outer margin expanded laterally; aedeagal dorsal body very wide, with apex laminar in lateral view; inner lamina sinuous, setose inside; outer lamina with series of grooves; base of aedeagal dorsal body slightly wider. Apodeme not extending beyond genital ring.

Remarks. This species is known to Brazil (Paraíba, Pernambuco, Espírito Santo, São Paulo, Paraná and Santa Catarina) and Argentina ( Colombo & Azevedo 2016). Now it is recorded for the first time from Panama. Some variations are worth to mention: head dark castaneous; frons strongly coriaceous; median clypeal tooth angulate; anterior margin of pronotal disc coarse; depression of tergal process very large; apex of paramere strongly curved inward.
