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.
