Type material. Holotype male: CHINA: Sichuan Province: Guangyuan City, Qingchuan County, Yaodu Town , 32.78°N, 105.44°E, 632 m, near road, 1 June 2013, L.Y. Wang & X.K. Jiang leg. (CBEE). Paratypes: 1 male and 3 females ( CBEE) , 1 male and 1 female ( SMF) with same data as holotype. Gansu Province : 2 females, Longnan City, Wen County, Liujiaping Town , 32.79°N, 104.82°E, 1224 m, near road, 31 May 2013, L. Y. Wang & X.K. Jiang leg. ( CBEE) .

Etymology. The specific name is dedicated to Mr Luyu Wang (SWUC) for his kind instructions on our Sparassidae collection; name in genitive case.

Diagnosis. Males of this new species resemble those of S. aequalis sp. nov. ( Figs 4 A–C, 4A–D) and S. apiculiformis sp. nov. ( Figs 7 A–C, 8A–D) in having a general similar palpal conformation, especially the embolus tip being as long as embolic apophysis and the tegulum covering the proximal part of embolus. Males can be distinguished from S. aequalis sp. nov. and S. apiculiformis sp. nov. by vRTA being more than half as long as dRTA

(slightly shorter in S. aequalis , three times shorter in S. apiculiformis ) ( Figs 40 A–C, 41A–D). Females are similar to those of S. brevis sp. nov. ( Figs 10 D–E, 12A–B) in having a narrow lobal septum and horizontal anterio-lateral margins of lateral lobes, but can be separated by: 1. Epigyne with posterior margin of epigyne almost straight (distinctly bilobate in S. brevis ); 2. Vulva with glandular appendages as wide as posterior parts of spermathecae (slightly narrower in S. brevis ) ( Figs 40 A–E, 41A–D, 42A–B).

Colouration in ethanol. As in males ( Figs 42 C–D).

Distribution. China (Sichuan; Gansu) ( Fig. 62 ).
