摘要

摘要/ Abstract摘要:1908年的Placobdella pediculata Hemingway，最初是在美国明尼苏达州Pepin湖的淡水鼓Aplodinotus grunniens(淡水鼓)上发现的。显然，没有类型物质沉积。从模式地的模式寄主那里获得的当代标本有助于对马先蒿的重新描述。马尾盘的不同之处在于其尾部吸盘由一个花梗(花梗)从身体伸出，在尾部吸盘边缘附近有指状突起，体表光滑，其肛门位置(尾部吸盘的前方有少量环空)。马先蒿细胞色素c氧化酶I亚基序列的分子比较表明，同源基因间的差异为13.8% ~ 17.4%。带马蹄莲是一个独特的种。

Redescription and Molecular Characterization of Placobdella pediculata Hemingway, 1908 (Hirudinida: Glossiphoniidae)

Abstract Placobdella pediculata Hemingway, 1908 was originally described from individuals that were attached to Aplodinotus grunniens (freshwater drum) in Lake Pepin, Minnesota, USA. Apparently, no type material was deposited. The acquisition of contemporary specimens from its type host in the type locality facilitated redescription of P. pediculata. Placobdella pediculata is different from its congeners in that its caudal sucker is extended from the body by a pedicel (peduncle), bears digitate processes near the rim of the caudal sucker, a smooth body surface, and its anal placement (few annuli anteriad of the caudal sucker). Molecular comparison of cytochrome c oxidase subunit I sequence data from P. pediculata revealed differences of 13.8% to 17.4% among congeners. Placobdella pediculata is a distinct species.
