A new puddle frog (phrynobatrachidae: Phrynobatrachus) from the mambilla plateau in eastern nigeria

Abstract

A new species of puddle frog (Phrynobatrachus) is described from the Kurmin Danko Forest Reserve on the western edge of the Mambilla Plateau in eastern Nigeria. The new species is distinguished from both geographically proximate and closely related Phrynobatrachus species by the combination of its body size (larger than the closely related P. chukuchuku, P. manengoubensis, and P. werneri), degree of development of male traits, and a unique ventral colour pattern in males. Molecular phylogenetic analysis reveals that this new species is closely related to P. werneri and P. manengoubensis, which, together with several other species, form a clade restricted to the mountains of the Cameroon Volcanic Line. This new Phrynobatrachus is the first known amphibian species hypothesized to be endemic to the Mambilla Plateau of eastern Nigeria. © 2010 Herpetological Association of Africa.
