Differential diagnosis
The male of S. australis sp. nov. shares with S. similis Shen & Yin, 2020 ( China: Zhejiang, Jiangxi) the similar body size and structure of the antennal clubs. These two species can be separated only by the following subtle differences: in S. australis sp. nov., the eyes are slightly larger, the dorsal margin of antennomere 11 is more convex, the upper (subbasal) protuberance of antennomere 11 is smaller, antennomere 9 in full view (when full widths are visible) is slightly more transverse and the apex of the aedeagus is narrower, and by their different distributions.
Etymology
The specific name indicates the distribution of the new species in southern China.

Antennal clubs ( Fig. 2B View Fig ) formed by antennomeres 9–11; antennomere 9 ( Fig. 2C View Fig ) slightly transverse, inner margin moderately expanded mesally, with single semi-membranous apophysis at apex of expansion; antennomere 10 strongly transverse, obconical; antennomere 11 ( Fig. 2B View Fig ) about 1.8 times as long as wide, each with two basal protuberances, more apical one short, rounded at apex, more basal one covered with two tufts of setae at apex ( Fig. 2D View Fig ). Pronotum about as long as wide. Elytra strongly transverse. Abdomen widest at tergite 1 (IV) and narrowing apically. Aedeagus ( Fig. 2E View Fig ) slightly asymmetrical at apex.
