Abstract

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).

 

Se informa de dos especies nuevas, Sensillonychiurus pseudogeminus sp. nov. y Sensillonychiurus zhuajiensis sp. nov. de la provincia de Heilongjiang, China. La especie S. pseudogeminus sp. nov. es muy similar a la especie S. geminus Pomorski & Sveenkova 2006, pero se puede distinguirla por el unguículo mas corto, las espinas anales mas largas y por la presencia de parapseudoceli esternales sobre los segmentos II y IV del abdomen, en lugar de pseudoceli. Se puede distinguir S. pseudogeminus sp. nov de los otros congéneres conocidos por su fórmula pso dorsal peculiar (32/144/44453).
