摘　　要：从大头狗母鱼Trachinocephalusmyops的消化道内检获细尾属1新种：厦门细尾吸虫，新种Eriepturusxiamenensissp.nov.。新种与狗母色细尾吸虫E.trachinocephaliYamaguti，1970和带鱼细尾吸虫E．trichiuriGuetShen，1978相似，但它们可以从虫体大小和虫卵大小以及其他形态特征相区别。The present paper deals with the digenetic trematodes of marine fishes collected from the sountheastern coast of China. After morphological comparison, onespecies of those worms, belonging to Erilepturus Woolcock, 1935, is new to science.The diagnoses of the new worm is given briefly as follows and it is deposited in theKey Laboratory of Marine Biology of Guangdong Province, Shantou University. Allmeasurements are in mm, exception ova in μm.Erilepturus xiamenensis sp. nov' (Fig.1)Host Trachinocephalus myops;Location Intestine;Locality Xiamen, Fujian Province, Shantou, Guangdong Province.Infection 90 speciments from 8 of 9 hosts;Type species 103 －21 － 1. deposited in the Key Lnboratory of Marine Biologyof Guangdong Province, Shantou University.Body elongate, 6.00 － 10.96 x 0.90 － 1.92 (7.57 x 1.322), divided into soma andexsoma, and the widest at ovarial level.

Seminal vessicle tubular, commencing between acetabulum andtestes zoon, usually sigmoid or winding, with its attenuated anterior end leading intopars prostatica, Pars prostatica 0.464 － 0.84 (0.672) long. Prostatic cellswell－developed, but without a membranous capsule. Hermaphoditic pouch bulbous,0.240 － 0.384 x 0. 184 － 0.288 (0.280 x 0.239). Hermaphoditic duct 0.200－ 0.288(0.242)long.
