Taxonomy and systematics

Ten of the species in this genus were formerly considered species of the genus Bufo, most of them in what had been known as the Bufo biporcatus group; the remaining ones were assigned to this genus based on molecular data.[1] In 2007 a new species, Ingerophrynus gollum, was added to this genus.[4] The sister taxon of Ingerophrynus is Sabahphrynus.[2]

Etymology

The generic name Ingerophrynus honors Robert F. Inger, an American zoologist from the Field Museum of Natural History.[1][5]

Description

The diagnostic characters of the Bufo biporcatus group are the presence of supraorbital, parietal, and supratympanic crests, lack of a tarsal ridge, presence of vocal sacs but absence of melanophores in the surrounding muscle tissue, lack of tibial glands, lack supinator manus humeralis and adductor longus muscles, presence of paired crests on the vertebral column, rugose skull, squamosal bones with broad dorsal otic plates, and smooth palatine bones.[4]

Species

There are 12 species:[2][3]
