Differential diagnosis

The male of S. transversus sp. nov. is most similar to that of S. usitatus from Yunnan in the similar form of the antennomeres 9 and 11, but can be clearly separated form it by the larger body size (2.61–2.72 mm vs 2.23–2.42 mm), more posteriorly located apophysis of antennomere 9 and longer basal protuberance of antennomere 11.

Etymology

The specific name refers to the strongly transverse antennomere 9 of the male.

Body ( Fig. 13A View Fig ) reddish-brown, mouthparts and tarsi paler. Head slightly longer than wide. Each eye composed of about 20 facets; LE:LT = 1.1. Antennal clubs ( Fig. 13B View Fig ) formed by antennomeres 9–11; antennomere 9 ( Fig. 13C View Fig ) strongly transverse, each with semi-membranous apophysis at apex of mesal expansion, and at approximately apical ²/5 of antennomere; antennomere 10 strongly transverse, obconical; antennomere 11 ( Fig. 13B View Fig ) about 1.4 times as long as wide, each with single moderately long basal protuberance covered with tuft of setae at apex ( Fig. 13D View Fig ). Pronotum about slightly longer than wide. Elytra moderately transverse. Abdomen widest at tergite 1 (IV) and narrowing apically. Aedeagus ( Fig. 13E View Fig ) slightly asymmetrical at apex.
