Differential diagnosis

The male of this new species shares with S. perpusillus Yin & Li, 2012 , S. vafelus Löbl, 1979 and S. minutus Löbl, 1979 the antennomere 11 bearing two small protuberances at the base of the mesal margin. This new species has the largest body size (1.70–1.91 mm), and can be readily separated from S. perpusillus (TBL = 1.48–1.52 mm) by the more distal position of the apophysis on antennomere 9; from S. vafelus (TBL 1.4–1.5 mm) by the relatively shorter antennomere 11 (length / width = 1.6) and less protruding basal protuberance on it; and from S. minutus (TBL = 1.3 mm) by the much larger body size and more relatively elongate antennomere 11.

Etymology

The new species is named after Linzhi City, where the type locality of this species is situated.
