Differential diagnosis
The male of S. chengzhifeii sp. nov. is most similar to that of S. huapingensis sp. nov. from Guangxi, China and S. larifuga Shen & Yin, 2019 from Sabah, Borneo, with which it shares the unique, subtriangular basal protuberance of antennomere 11. The new species can be separated from the former by the larger body size (2.69–2.81 mm vs 2.49 mm) and the more basal and more distal positions of the protuberance and apophysis of antennomeres 11 and 9, respectively; and from the latter by the relatively much smaller eyes in relation to the head, more elongate antennomeres 9 and 11, and more distal position of the apophysis of antennomere 9.
Etymology
The new species is named after Zhi-Fei Cheng, one of the collectors of the new species.

Description
Male
MEASUREMENTS. AeL = 0.25 mm; AnL = 1.25–1.29 mm; AL = 0.73–0.78 mm; AW = 0.86–0.89 mm; TBL = 2.69–2.81 mm; EL = 0.81–0.84 mm; EW = 0.98–1.02 mm; HL = 0.57–0.59 mm; HW = 0.55– 0.57 mm; LE = 0.21 mm; LT = 0.11 mm; PL = 0.58–0.60 mm; PW = 0.57–0.58 mm.
Body ( Fig. 4A View Fig ) reddish-brown, mouthparts and tarsi paler. Head approximately as long as wide. Each eye composed of about 20 facets; LE: LT = 1.9. Antennal clubs ( Fig. 4B View Fig ) formed by antennomeres 9–11; antennomere 9 ( Fig. 4C View Fig ) slightly elongate, each with long semi-membranous apophysis at basal ¼ of mesal margin; antennomere 10 strongly transverse, obconical; antennomere 11 ( Fig. 4B View Fig ) about 1.8 times as long as wide, each with single subtriangular and blunt basal protuberance covered with short tuft of setae at apex ( Fig. 4D View Fig ). Pronotum about as long as wide. Elytra strongly transverse. Abdomen widest at tergite 1 (IV) and narrowing apically. Aedeagus ( Fig. 4E View Fig ) flattened, slightly elongate, and slightly asymmetrical at apex.
Female
MEASUREMENTS. AnL = 1.27 mm; AL = 0.86 mm; AW = 0.95 mm; TBL = 3.0 mm; EL = 0.83 mm; EW = 1.05 mm; HL = 0.62 mm; HW = 0.60 mm; LE = 0.17 mm; LT = 0.16 mm; PL = 0.69 mm; PW = 0.65 mm.
Similar to male in size. Each eye composed of about 14 facets; LE:LT = 1.6. Antennal clubs lacking modifications.
