Incilius aucoinae Pacific Forest Toad
Some other names for this species:
Rainforest Toad
The genus Incilius was split from Bufo by Frost et al in 2006. This split is particularly controversial among herpetologists, and many references still use the long-established Bufo. Also, Ollotis was used by some references between 2006 and 2009.

Incilius aucoinae was considered part of Incilius melanochlorus until 2004. Now Incilius melanochlorus refers only to the similar toads on the Atlantic Coast, and Incilius aucoinae refers to those on the Pacific Coast.

Incilius aucoinae is a fairly standard-looking toad, though they vary quite a bit in color and pattern. Unlike the much larger Rhinella marina, which were common around human habitation, I. aucoinae were found only in the forest. The first one pictured here is a juvenile, about halfway grown. The second one is a full grown adult.

These toads were photographed on a herping trip with GreenTracks. Here is a complete list of the species we found on this GreenTracks trip.
