Abstract

A total of 17737 individuals of prosobranch snails, Semisulcospira spp., were collected from Lake Biwa and its tributaries, central Japan, from 1995 to 1999. They were examined for trematode larvae. One species of Aspidogastrea and 28 species of Digenea were detected. This paper briefly describes five of the 28 digeneans: a tetracotyle metacercaria from S. niponica, Cercaria A (cystophorous cercaria) from S. reticulata, Cercaria B (echinostomatid cercaria) from S. libertina, Cercaria C (magnacauda cercaria) from S. niponica and Cercaria D (mutabile cercarium) from S. nakasekoae. They were rare and every one of them was obtained from one snail only once.

摘要

1995年至1999年期间，从日本中部琵琶湖及其支流共采集了17737只前鳃亚纲螺类，即日本沼螺。对它们进行了吸虫幼虫检查。检测到1种盾腹吸虫和28种复殖吸虫。本文简要描述了这28种复殖吸虫中的5种：日本沼螺体内的四盘尾蚴后尾蚴、网状沼螺体内的尾蚴A（囊尾蚴尾蚴）、放逸沼螺体内的尾蚴B（棘口科尾蚴）、日本沼螺体内的尾蚴C（大尾尾蚴）和中川沼螺体内的尾蚴D（可变尾蚴）。它们很罕见，每一种都仅从一只螺中获得过一次。
