Abstract

Two new species of the tribe Oligaphorurini are described from northeast China: Dimorphaphorura jingyueensis sp. nov. and Oligaphorura chankaensis sp. nov. Dimorphaphorura jingyueensis sp. nov. is similar to Dimorphaphorura pseudoraxensis (Nosek & Christian, 1983) in having 1+1, 3+3, and 3+3 pso on Th. I–III, respectively. Both species can be distinguished by the number of pso on Abd. IV–V, the ratio of unguiculus/unguis, the inner basal lamella of the unguiculus, the number of chaetae in distal whorl of the tibiotarsi and of the apical teeth on mandible. Oligaphorura chankaensis sp. nov. is similar to the species O. montana Weiner, 1994 and O. pseudomontana Sun & Wu, 2012 in the same number of pso on the dorsal side of head and Th. I–Th. III terga (43/144), ventral pso formula (11/000/00000) and pso on subcoxa 1 of legs I–III (1, 1, 1). But the new species can be separated from them by the number of pso on abdominal terga, the ventral psx formula, the labial type, the number of chaetae on tibiotarsi I–III and the ratio of AS/unguis.
