Female holotype from Sierra Maestra , Cuba (presumably lost, not examined). WSC 2017 . Note. The author does not provide any illustrations and the description is insufficient to distinguish the species. According to G. Alayón Garcia (MNHC), species described by Franganillo were never found at Cuban Institutions, and are therefore considered lost. Therefore, we considered it as a nomen dubium .
