During his second reconnaissance visit to Mount Mabu (23–26 January 2006) Dr. Julian Bayliss found a very young forest viper in leaf litter on the floor of closed-canopy wet forest on Mount Mabu at approximately 1,000 m (3,300 ft). On examination in the Port Elizabeth Museum (BayWorld, acronym PEM) herpetological collection by Prof. Bill Branch, the specimen was identified as a member of the genus Atheris, which had never previously been recorded from Mozambique and which, moreover, represented a substantial southern range extension for the genus.
