Abstract
A new species of nematode, Orientatractis longicaudata n. sp. is described from the intestine of Indotestudo elongata (Blyth) (Testudinidae) from Zoo of Tianjin, Tianjin, China. The new species can be easily distinguished from its congers by having longer tail, by the length of gubernaculum and left spicule, and by the numbers of caudal papillae. This is first species of Orientatractis Petter, 1966 reported in China. A key to the species of Orientatractis is provided.
