What is "nimbaphrynoides"

Nimbaphrynoides is a small genus of true toads from highlands in the Mount Nimba region of the West African countries of Guinea, Liberia and Côte d'Ivoire. They are Critically Endangered due to habitat loss, and iron and bauxite mining within their small ranges. Traditionally two species are recognized, but in 2010 it was proposed that N. liberiensis should be considered a subspecies of N. occidentalis.

The two species are viviparous – they have internal fertilisation and the female give birth to fully developed, tiny toadlets. Until the description of Nimbaphrynoides in 1987, the two species were included in Nectophrynoides instead. Nectophrynoides, Nimbaphrynoides and Limnonectes larvaepartus are the only frogs/toads that do not lay eggs.
