Description

The dorsal surface can range from a dark-tan to a dark-gray color, and the surface of the skin is tubercular. The eye has a triangular pupil. This species is regarded by some workers as a subspecies of Bombina variegata (see that account for a longer description of morphology and coloration).

Bombina pachypus is regarded as a subspecies of Bombina variegata by some workers. It was initially separated from Bombina variegata by Lanza and Vanni (1991) due to genetic distance based on allozymes (Nascetti et al. 1982) and morphological differences (Vaccaneo 1931). Canestrelli et al. (2006) have argued for maintaining it as a separate species, based on analysis of mitochondrial and nuclear markers, and that Calabrian populations deserve special conservation status as the reservoir of significant genetic diversity for this species However, phylogenetic analysis by Hofman et al. (2007), using mitochondrial cyt b sequences, found that Italian populations were nested within B. variegata lineages, calling into question the validity of recognizing B. pachypus as a separate species.
