Abstract

Three new heligmonellid nematodes from the small intestine of the Pere DAVID'S vole Eothenomys melanogaster (MILNE-EDWARDS), captured at Doi Inthanon, Thailand, are described. They were Yatinema siamensis n. sp., which belongs to the subfamily Heligmonellinae DURETTE-DESSET, 1983,and is easily differentiated from Y. japonicum by a symmetrical bursa and barely developed ridges of synlophe. Carolinensis eothenomysi n. sp. and Neoheligmonella orientalis n. sp., which belong to the subfamily Nippostrongylinae DURETTE-DESSET, 1983,respectively, and differentiated from the known species of the both genera by the morphological characteristics of the bursal rays and synlophe. This is the first recording of the genus Neoheligmonella DURETTE-DESSET, 1971 in the Oriental subregion.
