Nectophrynoides is a genus of true toads, family Bufonidae. 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 and Limnonectes larvaepartus, they are the only frogs/toads in the world that do not lay eggs. The Ethiopian Altiphrynoides, which lay eggs, were also part of Nectophrynoides in the past.

Callulina shengena is a species of frogs in the family Brevicipitidae. It was discovered in 2010 during a survey of rainforests in the northern part of the Eastern Arc Mountains of Tanzania. It is present at two locations in Chome Forest Reserve at altitudes between 1,920 and 2,100 m. The forests in which it lives are being selectively felled, and the International Union for Conservation of Nature has rated its conservation status as "critically endangered".
Callulina stanleyi is a species of frogs in the family Brevicipitidae. It was discovered in 2010 during a survey of rainforests in the northern part of the Eastern Arc Mountains of Tanzania. It was named in honour of the American zoologist, William T. Stanley, of the Field Museum, Chicago, who has done much research into the amphibians of Tanzania. It is present at three locations along the eastern border of Chome Forest Reserve at altitudes between 1,100 and 1,300 m.
