Redescription of Desportesius invaginatus (Linstow,1901)(Spirurida:Acuariidae) Collected from Cattle Egret,Bubulcus ibis coromandus in Henan Province

2006年5月对采自河南省信阳地区的一只牛背鹭进行解剖,从砂囊内检获一批线虫,经鉴定为缩迭脱门线虫Desportesius invaginatus(Linstow,1901)。本文主要对该种线虫进行了描述。本种线虫与前人的描述基本相同,但所采标本虫体尾部较短,雌虫尾端内陷。该种线虫在河南省属首次报道,为河南省新记录种。

Desportesius invaginata （ Linstow, 1901 ） Chabaud and Campana, 1949 was collected from lining of the gizzard of the cattle egret, Bubulcus ibis coromandus in Xinyang, Henan Province. The redescription of this species is given in the present study. Our specimens are very similar to that of reported previously in general characters, but differ from the latter in having shorter tail of male and female, and in having a sunken female tail.
