Two new species, Sensillonychiurus pseudogeminus sp. nov. and Sensillonychiurus zhuajiensis sp. nov., are reported from Heilongjiang Province, China. S. pseudogeminus sp. nov. is very similar to the S. geminus Pomorski & Sveenkova 2006, but it can recognized by shorter unguiculus, longer anal spines and presence of sternal parapseudocelli on Abd. II and Abd. IV instead of pseudocelli. Sensillonychiurus zhuajiensis sp. nov. can easily be distinguished from other known congeners by its peculiar dorsal pso formula (32/144/44453).
