On two new species of the cestode genus Oochoristica from Lizards

Abstract

The cestodes of lizards have received little recent attention from systematic zoologists. Those inhabiting snakes are much better known than they were a few years ago, thanks to the researches of La Rue (1914) and of Rudin (1917). The cestodes of snakes almost all belong to the family Ichthyotaeniidae (genera Crepidobothrium, Ophiotaenia, Acanthotaenia). Among the lizards also, several species of Acanthotaenia occur in the Monitors (Varanus), and one is recorded in Lialis, one of the Pygopodidae. The Monitors are also the hosts of a remarkable genus of quite a different type—Duthiersia—our knowledge of which has recently been brought up to date by Beddard (1917), and of another genus—Pancerina—of an equally distinct type.
