SSAR 9th Edition Comments:
Although only two species are currently recognized within this genus, very strong geographic variation in coloration, call, and toe structure suggests that several species are masquerading under this species name. Given that the type locality of H. variolosus is in Costa Rica, the scientific name applied to the U.S. form is likely to change.

Taxonomic Etymology:
A stout-bodied frog with a pitted, warty skin.
Hypopachus — From Greek hypo- (ὑπό), “under,” and pachys (παχύς), “thick.” The name likely refers to the frog’s thick, robust body or thick skin from below.
variolosus — From Latin variola, “smallpox,” and -osus, “full of.” Means “pockmarked” or “covered in pits/warts,” referring to the frog’s textured, pustulate skin.
