【Abstract】 Eleven species of parasitic helminths belonging to seven families ten genera have been obtained from the marine turtle in Fujian province. Among these three are described to be new to science. diagnosis of which are given as follows: 1. Plesiochorus pirijorms, sp. nov. (fig. 1) Habitat: Intestine of Chelonia mydas This species differs from the ;colsely related P. cymbiforms (Rudolphi, 1891) Looss, 1901and P. cymbiforms elongatus Pigulevsky, 1953 chiefly in the body in size, testes whithout deep lobate, orary round and uterus between in the both intestine region. 2. Paralepoderma cheloniae sp. nov. (fig.2) Habitat: Intestine of Chelonia mydas This species differs from the closely related P. cloacicla (Liihe, 1909) Doffus, 1950 chiely in the larger body (8.5-11×0.30-0.35mm), testes oval or irregular in shaped, the two intestine extending to posterior of the body, eggs 52. 5-63× 17.5-21 μ in size. 3. Orchidasma cheloniae sp. nov. (fig. 3) Habitat: Intestine of Chelonia mydas This species differs from the closely related O. amphiorchis (Braum, 1899) Braun, 1901 chiefly in the testes in round-shaped, vitellaria extending to anterior, margin of posterior testes, eggs 46×44μ in size.更多还原
