摘要

记述了锚首虫科Ancyrocephalidae单殖吸虫中国一新纪录属及一新种和一新纪录种,即异茎虫属Heteropriapulus(Jogunoori,Kritsky & Venkatanarasaiah,2004)Kritsky,2007,简单异茎虫Heteropriapulus simplex sp.nov.,异突异茎虫Heteropriapulus heterotylus(Jogunoori,Kritsky & Venkatanarasaiah,2004) Kritsky,2007.该新种的支持器为简单的直片状,与本属唯一已知种——异突异茎虫复杂的支持器不同.文中对新种和新纪录属种做了新的形态描述并给出特征图.%Heteropriapulus ( Jogunoori, Kritsky & Venkatanarasaiah, 2004) Kritsky, 2007 (Monogenea, Ancyroceph-alidae) is reported in China for the first time, with the description of one new species and one new recorded species parasitized on gills of Heteropriapulus simplex sp. Nov. , and Heteropriapulus heterotylus( Jogunoori, Kritsky & Venkatanarasaiah, 2004) Kritsky, 2007. The supporting apparatus of new species is simple straight flake, different from the complicated supporting apparatus of H. Heterotylus, the only known species of the genus. The morphology and features of Heteropriapulus, H. Heterotylus and new species are described in the present study.
