The species Lathecla carolyna Busby, 2015 described recently from Ecuador is reported to occur also in Venezu- ela and Colombia. An additional Peruvian occurrence of L. mimula (Draudt, 1920) is also documented. Keywords. Colombia, Ecuador, wet forests, Peru, sampling, Venezuela.

In Venezuela, the species was found in a lateral aspect without terminal pincer-like similar biotope as in Ecuador, in moist montane extension, and an aedeagus deeply open dorsally forest at 1800 m asl.
