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.
