Differential diagnosis

The male of S. huapingensis sp. nov. possesses a roundly triangular basal protuberance of antennomere 11, similar to that of S. chengzhifeii sp. nov. ( China: Yunnan) and S. larifuga (Borneo: Sabah). Sathytes huapingensis sp. nov. can be separated from S. chengzhifeii sp. nov. by the smaller body size ( 2.49 mm vs 2.69–2.81 mm), and the more distal and more basal positions of the protuberance and apophysis of antennomeres 11 and 9, respectively; and from S. larifuga by the relatively much smaller eyes in relation to the head, much narrower apical portion of the median lobe of the aedeagus, and a different distribution.

Etymology

The new species is named after Huaping Nature Reserve, where the type locality of this species is situated.
