Examined material. Holotype ♂, paratypes 4♂ and 2♀ (LKCNHM), SINGAPORE: Bukit Timah Nature Reserve, Seraya Loop, 103°46.422′N, 1°21.423′E, altitude 118 m, 17 August 2015, S. Li and Y. Tong leg.

Other material examined. 3♂ and 2♀ (NHMSU), SINGAPORE: Bukit Timah Nature Reserve, Seraya Loop, 103°46.422′N, 1°21.423′E, altitude 118 m, 17 August 2015, S. Li and Y. Tong leg.

Diagnosis. Male of S. lenachanae can be distinguished from males of all other congeners except for S. banxiaoensis (Fig. 6B, b), S. halongense (Fig. 6A, a) and S. singulare (Fig. 6C, c) by the unbranched embolic tip, and the narrow, straight embolus (Fig. 6D, d vs. Fig. 6E–H, e–h). It differs from male of S. banxiaoensis by the lower ventral initial position of embolus (Fig. 6D vs. Fig. 6B), the wider embolic tip (Fig. 6d vs. Fig. 6b). From male of S. halongense by the smaller palpal tibia (Fig. 6D vs. Fig. 6A), and the smoother, no curved edge of embolic tip (Fig. 6d vs. Fig. 6a). From male of S. singulare by the blunt embolic tip (Fig. 6d vs. Fig. 6c), the shorter palpal bulb and the lower ventral initial position of embolus (Fig. 6D vs. Fig. 6C, higher position indicated by a blue arrow). Female of S. lenachanae can be distinguished from the females of all other congeners except for S. singular by the absence of central process (Fig. 9B vs. Figs 2E, 5C–D, 7A–C, 8A–B). Female of S. lenachanae is closer to S. singulare in having similar configuration of vulva (Fig. 9A–B), but it differs from S. singulare by the longer lateral horns and the wider, straight vulval ducts (Fig. 9B vs. Fig. 9A).
