Dissomphalus bilobatus Azevedo, 1999a : 0 4, 0 9, 20–22 (♂, holotype from Trinidad & Tobago, CNCI, figs 71–77).

Diagnosis. Mandible oblique without teeth. Tergal process with very large depression hlaf-moon-shaped, with two low median tubercles and tuft of setae. Hypopygium with posterior margin slightly convex. Genitalia: paramere with deep median longitudinal invagination, dorsal lobe larger, apex wide, concave with corners rounded; ventral lobe thin, small, apex with setae; aedeagal ventral ramus shorter than aedeagal dorsal body, wide with apex truncate; surfaces divergent dorsally; ventral part of apex divided longitudinally with two serrated lamina; outer lamina small and narrowed apically and inner lamina larger; aedeagal dorsal body not developed narrowing apically; inner margin straight and parallel and outer margin convergent. Apodeme not extending beyond genital ring.

Remarks. This species is known to Costa Rica (Azevedo 1999). Now it is recorded for the first time from Panama. Some variations are worth to mention: mesosoma light castaneous; median clypeal tooth angulate; median clypeal carina complete; vertex crest straight; anterior margin of pronotal disc coarse; pit of tergal process with very short tuft of setae.
