摘要
从福建沿海的侧条真鲨的体腔内发现发状科的中国连盘吸虫,新种Anaporrhutum sinicum sp. nov., 虫体大小11.0×4.5mm,卵41—56×18—20μm。这是国内首次报道连盘属吸虫及本科的海水种类。又从福州淡水鱼类鲶鱼的肠道发现隐殖科的叶巢外睾吸虫,新种Exorchis ovariolobularis sp. nov., 虫体大小0.340×0.342mm,卵11—14×7—9μm。
In the examination of marine and freshwater fishes for digenetic trematodes in coastal areas of Fujian, China, one new gorgoderid and one new cryptogonimid trematode were collected. The type specimens are deposited in the Laboratory of Parasitology, Xiamen University. Their diagnoses are as follows:1. Anaporrhutum sinicum sp. nov. (fig. 1) Habitat Body cavity of a shark, Carcharhinus fleurotaenia. Locality Fuzhou (26°05’N, 119°18’E), Fujian Province.This species differs from the related A. albidum Ofenheim, 1900 chiefly in the smaller number of testes (13 on each side), which are situated extracecally and in a narrow region, the lobed ovary, lobed vitellaria not being branchy and larger size of eggs (41-56×18-20μm). This is the first record of the trematodes belonging to genus Anaporrhutum in China.2. Exorchis ovariolobularis sp. nov.(fig. 2) Habitat Intestine of freshwater fish Parasilurus asotus. Locality Fuzhow (26°05’N, 1I9°18’E), Fujian Province.This species differs from the related E. oviformis Kobayashi, 1915 and E. multivitellaris Pan, 1984 chiefly in the larger lobed ovary (E. oviformis has a smaller lobed ovary and E. multivitellaris has a round or oval ovary), and smaller size of eggs (11-14×7-9 μm).
