As in female but with mesosoma black in the areas that are blackish brown in the female, and with metasomal tergites entirely black. Other features as in female. Remarks. The three males assigned to this species are larger than the female and were collected in another locality, but are very similar in structure and colour pattern, so they are tentatively assigned to C. andaki. Etymology. This species is named in honor to the Colombian indigenous tribe of Andakis (or Andaquíes), who live in southern Dept. of Huila, where the holotype was collected.
