(2012) provided a key for the Cuban species of Calisto , using both morphological and biogeographical data. Since then, eight new species and two subspecies have been described for the Cuban fauna, and so the original key is now obsolete. Thus, we propose an updated key with all known Cuban Calisto taxa, including the subspecies named herein. We illustrate with live specimens all taxa except C. siguanensis Núñez & Barro and the typical subspecies of C. disjunctus ( Fig. 7 ). 1 UN surface colour very dark brown; no red scales on the UNFW cell; triangle of white scales along the inner margin at the UNHW ; FW length: 22–26 mm ♁, 25–27 mm ♀ ; exclusive to Nipe-Sagua-Baracoa mountains....................................................................................................
