摘　　要：调查华北地区无尾两栖类复殖吸虫，获６ 科１１ 种，其中包括一个新种和两个宿主新记录．脐宫科的华北长囊吸虫，新种Ｄｏｌｉｃｈｏｓａｃｃｕｓ ｈｕａｂｅｉｅｎｓｉｓｓｐ． ｎｏｖ．枝腺科２ 种，其中中华斜生吸虫Ｌｏｘｏｇｅｎｅｓ ｓｉｎｅｎｓｉｓ（ＬｉｅｔＧｕ，１９７８） Ｗａｎｇ， １９８０，寄生于金线蛙，为宿主新记录．蛇颈科的罕见蛇颈吸虫Ｇｏｒｇｏｄｅｒａ （Ｅｘｔｒｅｍ ｏｄｅｒａ）ｕｎｅｘｐｅｃｔａ ，也寄生于金线蛙，为宿主新记录，并首次见于输卵管部位．此外尚有重盘科吸虫３ 种，拟巨颈科１ 种和舐血科１North China included Beijing City, Tianjin City, Hebei Province, Shanxi Province and Neimongol Autonomous Region. In 1985~1988, 9 species of digenetic trematodes of frogs belonging to 6 families have been collected from this region. Measuring unit:mm. DIPLODISCIDAE 1.Diplodiscus amphichrus Tubangui, 1933 2.Diplodiscus mehrai Pande, 1937 3.Diplodiscus japonicus (Yamaguti, 1936) Li, 1937 OMPHALOMETRIDAE 4.Dolichosaccus huabeiensis sp. nov. Body lanceolate 1.782~3.604×0.431~0.607, ratio between length and width of body 5.8~6.2∶1. Cuticle smooth. Oral sucker 0.188~0.352×0.203~0.352. Acetabulum 0.109~0.195× 0.109 ~0.156, situated on anterior line of fourth of body. Suckers ratio 1∶0.5~0.58. Prepharynx indistinct 0.035, Pharynx 0.102~0.195×0.141~0.211, elliptical. Oesophagus 0.117~0.305. Caeca extending to posterior extremity of body. Testes tandem or slightly oblique and close together. Anterior testis 0.148~0.258×0.148~0.273 located in equator, posterior testis 0.164~0.322×0.156~0.266. Cirrus pouch 0.156 ~0.352×0.039~0.094,enclosing seminal vesicle, prostatic gland portion and ejaculatory duct. The base of pouch reaching middle level of ovary.Seminal vesicle winding. Genital pore situated slightly left of preacetabulum. Ovary 0.113~0.195×0.109~0.180 lying right and posterior of acetabulum. Mehlis gland 0.117~0.234×0.117~0.253, behind ovary or slightly left. Seminal receptacle triangular or spherical 0.117~0.148. Uterus coiled between acetabulum and anterior testis, extending extracaeca. Metraterm well developed. Eggs elliptical 39.6~43.6μm×21.8~25.7μm. Vitellaria extending from the level of oesophagus to posterior extremity between sides of body. Excretory bladder tubular, extending to testes. This species differs remarkably from D. linwai (Lu, 1978) and D. schmidti Fischathal et Kuntz, 1975 in (1) suckers ratio 1∶0.5~0.58,(2)vitellaria extending from the level of oesophagus, (3) testes situated in equator, (4) body cuticle smooth, (5) size of ovary and eggs and (6) host
