鱼居叉盘吸虫的再描述及其地理新记录

A REDESCRIPTION AND A NEW GEOGRAPHICAL RECORD OF WARETREMA PISCICOLA SRIVASTAVA, 1939 (TREMATODA: WARETREMATIDAE) IN SOUTH CHINA SEA

在我国首次从南海的金钱鱼Scatophagusargus(Linnaeus)消化道里检获鱼居叉盘吸虫Ware tremapiscicolaSrivastava,1939,并对其形态结构进行重新描述和绘图。比较了来自不同宿主的鱼居叉盘吸虫的大小及形态结构。

Waretrema piscicola Srivastava, 1939 (Trematoda: Waretrematidae) was recorded from Scatophagus argus(Linnaeus) in the South China Sea.This finding represents a new geographical record. This specie was firstly described by Srivastava (1939) from Mugil waigiensisof Karachi, and then by Velasquez (1961) from Scatophagus argusof Philippines and by Machida (1996) from Crenimugil crenilabisof Japanese and adjacent waters. My specimens agree with their descriptions in general features, but differ from Srivastava′s specimens in having smaller bodies and structures, from Velasquez′s specimens in having uterine seminal receptacles instead of seminal receptacles, and from Machida′s specimens in the arrangements of the oral projections, in the shape of vitellaria, and in tegument spines instead of smooth.
