Abstract

A new extant Donuea (Liocranidae) species is described from Madagascar, from both alcohol preserved fresh material and also as a subfossil in copal from the Sambava area. X-ray micro computed tomography was used to visualise minute details of the male palp of the copal specimen in order to confirm conspecificity. This is the first time a new spider species discovered in Madagascan copal can immediately be demonstrated as belonging to an extant species.
