A morphology-based identification key to the Cognettia species of the world (Clitellata: Enchytraeidae)

Abstract

Morphological characters for identification of Cognettia species are presented both as a dichotomous key and in table form. Focus is on non-sexual characters, as many species reproduce mainly asexually, and sexually mature individuals can be rare.
