Atheris matildae, also known as Matilda's horned viper, is a species of arboreal forest viper endemic to Tanzania.


It was discovered in the Southern Highlands of Tanzania during a 2010–2011 biological survey. The exact location of the viper is unspecified, to protect it from being collected for the illegal pet trade.[1] The snake was described as a new species on December 6, 2011, in a study published in the journal, Zootaxa. A captive breeding colony has already been established by the authors of the study.[1]


The species is most likely a nocturnal hunter, waiting by streams to ambush frogs.


It resembles Atheris ceratophora, the Usambara bush viper.[2][3]

Conservation status[edit]

Matilda's horned viper occupies only a small area further threatened by logging and charcoal production.

Origin of name[edit]

A. matildae was named after Matilda, the daughter of Tim Davenport, the director of the Wildlife Conservation Society in Tanzania and a member of the three-person team to have discovered the snake.[4]
