Species Atheris matildae

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. 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.

Origin of Name

The viper 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.


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


It resembles Usambara Bush Viper (Atheris ceratophora).

Conservation Status

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