A new species of Echinochasmus was found in the small intestine of civet, Vivcrricula indica, collected from Hangzhou (30°16’N, 120°10’E), Zhejiang Province, China. The type specimens are deposited in the Department of Biology, Hangzhou Normal College.Echinochasmus hangzhouensis sp. nov. (fig. 1)This species differs from all known species of the genus in vitelline follicles extending from level of acetabulum to end of body; having vitellaria follicles confluent in front of testes and behind testes. The new species is most closly related to Echinochasmus perfoliatus and E. schwartzi, but differs from them in: (1) body smaller; (2) spine extending from head to middle of body; (3) oesophagus longer; (4) testes nearly spherical; (5) different position of vitelline follicles and (6) eggs fewer.
