The taxonomy, zoogeography and biology of Bipalium kewense Moseley, 1878 (Tricladida, Terricola)

Abstract

Knowledge of this cosmopolitan land planarian is briefly reviewed. The external morphology and anatomy of the copulatory organs are considered with emphasis on the variation of taxonomic characters. This species can be distinguished from similar planarians by differences in markings, particularly those of the head and neck; positions of body apertures and structure of the copulatory organs.
