Diagnosis. This species resembles S. aequalis sp. nov. (Figs 4 A–E, 5A–D, 6A–B), but can be separated by: 1. Male palp with dRTA narrower, its margins undulating (slightly wider, margins smooth in S. aequalis); 2. Female vulva with glandular appendages distinctly wider than posterior parts of spermathecae (about same width in S. pengi). Male of S. pengi also resembles that of S. apiculiformis sp. nov. (Figs 7 A–C, 8A–D) in having ageneral similar palpal conformation, especially the embolus tip being as long as and parallel to the embolic apophysis, but it can be distinguished from S. apiculiformis by: dRTA as two times as long as vRTA in retrolateral view (three times in S. apiculiformis); cymbium distinctly longer than tibia (slightly longer in S. apiculiformis).

Colouration in ethanol. Dorsal prosoma almost uniformly yellowish-brown, with yellowish-brown transversal band posterior to fovea. Fovea and radial furrows distinctly marked. Labium and gnathocoxae yellowish-brown, both with distal parts lighter. Sternum yellowish-brown. Chelicerae deep reddish-brown. Legs yellowish-brown with dark spots.

Distribution. China (Yunnan) (Fig. 62).
