New Trematodes from the Newt <i>Triturus viridescens</i>

Abstract

The writer has found three apparently new species of trematodes in the newt, Triturus viridescens Rafinesque. The newts were collected near Durham and Lakeview, North Carolina, and a study is being made to determine if there is any seasonal periodicity in the occurrence of their parasites. It is of interest that one trematode, Opisthodiscus americanus , is the first species of its genus to be reported for North America. Only one species of Brachycælium has been reported previously for North America and another, B. trituri , is described in this paper. A new species, Gorgoderina intermedia , is also described.
