Hoplophryne is a genus of microhylid frogs.[2][3][4] The genus is endemic to mountain forests of Tanzania.[2][4] They are also known as three-fingered frogs[2][4] or African banana frogs[2] (not to be confused with Afrixalus, another African genus known as "banana frogs"[5]).

Species

There are two species in this genus,[2][3][4] both endangered:[6]

  • Hoplophryne rogersi Barbour and Loveridge, 1928
  • Hoplophryne uluguruensis Barbour and Loveridge, 1928

Description

Hoplophryne are small frogs, reaching 32 mm (1.3 in) in snout–vent length (female H. rogersi).[4] Their distinctive characters is that male frogs have only three fingers: the thumb is reduced to a small bump or group of spines.[1][4]

Ecology and reproduction

Hoplophryne can be found in leaf litter,[4] under logs, and in bananas and bamboos.[1] Reproduction takes place in phytotelmata. The modified thumbs of males are probably involved in mating, helping the male to embrace the female.[1]
