Type material.

Holotype ♂ and paratype 1♂ (IZCAS), CHINA: Sichuan Province, Garze Prefecture, Kangding County, Jintang-Kongyu Nature Reserve (30.52280°N, 102.06210°E), 18.IV.2004, S. Li leg.

Etymology.

The specific name is derived from the type locality; adjective.

Diagnosis.

Males can be easily distinguished from those of the other congeners by the caniniform distal process of the paracymbium (Dp) (Fig. 3E, H). Another character to separate them from males of Hamus bowoensis , Hamus cornutus sp. n. and Hamus mangunensis sp. n. is the wider terminal apophysis with a blunt and short process I (Ta-I) (Fig. 3 F–G), whereas the entire Ta is a large C-shape in Hamus bowoensis (see Ballarin and Li 2015: 180, fig. 1 B–C) and Hamus mangunensis sp. n. (Fig. 5A, C) and shaped as an inverted comma with a missing Ta-I in Hamus cornutus sp. n. (Fig. 1A).

Description.

Habitus as in Fig. 3 A–C. Carapace faint yellow. Mouthparts and sternum pale yellow. Legs uniformly faint yellow. Opisthosoma uniformly yellowish without dark pigmentation.

Male palp (Fig. 3 D–H): paracymbium broad, with an lobed ventral apophysis and a lamellar, translucent dorsal apophysis, ending with a strongly sclerotized, dentiform distal process (Fig. 3 G–H). Ventral apophysis lobed, slightly sclerotized (Fig. 3 G–H). Terminal apophysis well-developed, strongly sclerotized, Ta-I blunt and short, Ta-II sharp and turned up (Fig. 3D, F–G). Two blunt processes at the base of the conductor, Cp-I short and stumpy, Cp-II laminar and elongate forming a curved groove (Fig. 3D).

Male (holotype). Total length 1.48. Carapace 0.79 long, 0.68 wide. Opisthosoma 0.78 long, 0.60 wide. Clypeus height 0.16. Sternum 0.48 long, 0.48 long. Leg measurements: see Appendix A.
