以下是胎生蟾属的物种：

Nectophrynoides is a genus of true toads. They are endemic to Eastern Arc forests and wetlands in Tanzania, and all except N. tornieri are threatened. Species of the genus are ovoviviparous: fertilization is internal, and the females give birth to fully developed, small toadlets. Together with the West Africa Nimbaphrynoides (which was included in Nectophrynoides in the past) and Limnonectes larvaepartus, they are the only frogs/toads in the world that do not lay eggs. The Ethiopian Altiphrynoides (includes Spinophrynoides), which lay eggs, were also part of Nectophrynoides in the past.
