Abstract
Two new species, Sensillonychiurus changchunensis sp. nov. and Thalassaphorura macrospinata sp. nov., from the tribeThalassaphorurini are described from Northeast China. S. changchunensis sp. nov. belongs to the group of species withoutAS and differs from all of them by having 5 papillae in AIIIO and more chaetae on Th.I. The number of dorsal S-chaetae,number of guard chaetae in AIIIO, position of ms on Ant. IV and relative length of unguiculus are also useful for identi-fication of these species. T. macrospinata sp. nov. belongs to the group with pseudocellar formulae as 32/233/33343 dor-sally and 11/000/01120 ventrally, but it can be easily recognized by the combined characters as almost cylindrical shapeof body, only one sublobal hairs on maxillary palp, inner basal lamella on unguiculus absent, one axial chaeta m0 on Abd. VI tergum and presence of male organ on ventral tube.References
