<正> 从湖北省产的鳖Trionyx sinensis(Wiegmann)体内采得两种后睾科吸虫,经鉴定为新种,并建立一个新属以容纳其中的一种。文中量度以毫米为单位,括弧内为平均值。 1、武汉后睾吸虫Opisthorchis Wuhanensis新种, 体形似柳叶,前端渐细。后端稍尖,3.81—4.74×0.76—1.02(4.19×0.88)表皮被小棘,排列整齐,向后渐稀疏,近肠支盲端而止。口吸盘亚端位,圆形,直径0.361—
Two trematodes of the family Opisthorchiidae were collected from the turtle, Frionyx sinensis (Wiegmann) in Hubei Province. They are described in this paper as new species and a new genus is erected for one of them. All measure- ments are in mm. 1. Opisthorchis wuhanensis Chin et Zhang, sp. nov. Body in the form of a willow leaf, spinose, 419×0. 88. Oral sucker 0. 380 Acetabulum 0. 24, located at the anterior third of body. A conspicuous shortpre pharynx present in specimens fixed in a more relaxed condition. Intestinal crura rather bsavy, reaching to the end of body. Testes 0. 28--0. 40, round, tandem, in posterior quarter of the body length. Seminal vesicle tubular, behind acetabulum, with genital opening in front of the latter. Ovary round, 0. 15×0. 12, in front of the anterior testis with a rather large, suecular seminal receptacle in between. Laurer's canal present. Vitellaria lateral, continuous, running from middlebetween intestinal bifurcation and acetabulum and reaching in front of ovary. Uterus between acetabulum and ovary, intercecal. Eggs 0. 026×0. 017. Collected from the hind portion of the digestive tract and in gall bladder of Trionyx sinensis (Wiegmann), Hubei Province. 2. Trionchotrema taenioidea Chin et Zhang, gen. et sp. nov. Trionychotrema Chin et Zhang, gen. nov. Opisthorehiidae: Body slender, with the sides nearly parallel and the posterior end round and slightly invaginable. Cuticle with fine longitudinal wrinkles. Oral sucker larger than acetabulum which is located in the anterior third of body. Prepharynx absent. Intestinal crura heavy, not reaehing posterior extremity. Testes rouad, diaoonal, in hind part of body. No cirrus sac. Seminal vesiele posterior to acetabulum with genital pore in front of the latter. Ovary oval, anterior to and away from the anterior testis. Seminal receptacle closely behind ovary. Laurer's canal present. Vitellaria lateral, interrupted, commencing in front of acetabulum and reaching to testes. Parasitic in gall bladder of turtles. Type species, Trionychotrema taenioidea Chin et Zhang Trionychotrema taenioidea Chin et Zhang, gen. et sp. nov. Living specimens orange red in color. Body slender, 14. 5-19 x 1. 08-1. 10, wlth the hind tip in an obtuse arch and slightly invaginable. Oral sucker 0. 40-0. 53. Aeetabulum 0. 17-0. 21 at anterior third of body. Prepharynx want- ing. Pharynx 0. 28-0. 36. Oesophagus 0. 28--0. 80. Intestinal crura heavy, ending in front of hind end. Excretory bladder Y-shaped running between the testes and bifurcating anterior to the front testis. Testes 0. 32-0. 45, round, diagonal away from each other, in the hind fifth of the body. Seminal vesicle prominent, tubular, winding closely behind aceta- bulum. Genital pore directly in front of acetabulum. Ovary oval, 0. 30, in front of the anterior testis. Seminal receptacle large, closely behind ovary, 0. 59×0. 32. Laurer's canal present. Vitellaria distributed from anterior of acetabulum to testes, with 3 or 4 interruptions on each side. Uterus between ovary and acetabulum, interceeal. Eggs small, 0. 029×0. 021. Specimens collected from the gall bladder and liver of Trionyx sinensis (Wiegmann) , Hubei Provinee.
