Abstract

Metacercariae from yellow-brown broodsacs parasitizing Succinea ovalis Say in Nebraska develop into adult Leucochloridium variae in the cloaca of chicks. Sporocysts, broodsacs, metacercariae, and adults are described and figured. Adults have a finely spined cuticula and an elongate, finely spined cirrus not described previously. Broodsacs resemble closely the "Rensselaerville" ones described by Ingram and Hewitt and those of L. fuscostriatum, which may be a synonym of L. variae. Reports of larval leucochloridiids from physid and planorbid snails are questioned. This is the first account of L. variae in Nebraska and the first description of its sporocyst and metacercaria.
