Remarks. Cibyra meridionalis is easily distinguished from the other two members of the species-group by the lack of an epiphysis. Furthermore, it is smaller, most specimens having a wingspan of about 30 mm, while the average wingspan is 40 mm in the other two previous species. It is the most frequent species at light in semi-deciduous forest during the summer. Sympatric to C. ochracea within this species-group.
