Abstract

Holotype and paratype of Ascocotyle (Phagicola) rara Arruda, Muniz-Pereira et Pinto, 2002, a heterophyid trematode recently described on the basis of two worms collected by Lauro Travassos in 1921 in the intestine of Ixobrychus exilis (Gmelin) from Brazil, were studied. The morphology of the worms revealed their conspecificity with Ascocotyle (Phagicola) angeloi Travassos, 1928 found in the same host. Both the taxa have a similar length (between 600 and 900 microm) and shape of the body (long pyriform), the long intestinal caeca reaching to the ovarian level, a long posterior muscular prolongation of the oral sucker and the prepharynx, transverse uterine loops situated between the ventral sucker and testes, and the gonotyl with more than 20 digitiform pockets. Consequently, A. (P.) rara is proposed as a junior synonym of Ascocotyle (Phagicola) angeloi.

摘要

对2002年阿鲁达、穆尼斯 - 佩雷拉和平托描述的罕见艾氏吸虫（噬口艾氏吸虫属）的正模标本和副模标本进行了研究，该异形吸虫是基于1921年劳罗·特拉瓦索斯在巴西小苇鳽（格梅林）肠道中采集的两条虫体最近描述的。虫体形态显示它们与1928年在同一宿主中发现的安氏艾氏吸虫（噬口艾氏吸虫属）同种。这两个分类单元体长相似（600至900微米之间），身体形状相同（长梨形），长肠盲囊延伸至卵巢水平，口吸盘和咽前有长的后部肌肉延伸，子宫横袢位于腹吸盘和睾丸之间，生殖腔有20多个指状囊袋。因此，提议将罕见艾氏吸虫（噬口艾氏吸虫属）作为安氏艾氏吸虫（噬口艾氏吸虫属）的次异名。
