The Brazilian gold frog (Brachycephalus didactylus), also known as Izecksohn's toad

endemic to southeastern Brazil and is known from the central part of the state of Rio de Janeiro and from Serra das Torres in extreme southern Espírito Santo.[3]

All three English names are misleading or potentially confusing. Many species in the genus

B. hermogenesi, was described in 1998 and two others, B. pulex and B. sulfuratus, have been described since then, bringing it to four species of flea-frogs/toads.[5]

Comparison with other small frog species

At 8.6–10.2 mm (0.34–0.40 in) in snout–to–

Eleutherodactylus iberia from Cuba were once regarded as the smallest,[7] but several others that are smaller have since been discovered, including the closely related B. pulex at 8–8.4 mm (0.31–0.33 in),[6] Stumpffia contumelia from Madagascar at 8–9 mm (0.31–0.35 in),[8] and Paedophryne amauensis from New Guinea at 7–8 mm (0.28–0.31 in).[9]
