Houshenzinus rimosus gen. n. sp. n. , paratype. 48–50 male carapace (lateral, dorsal and frontolateral views, respectively, not to scale), 45, 46 left palp (45 retrolateral view, 46 prolateral view), 47 paracymbium (lateral view). Abbreviations: ED embolic division, SA suprategular apophysis. FIGURES 51–58. Shaanxinus rufus gen. n. sp. n. , paratype (51–56), & Shaanxinus anguilliformis (Xia, Zhang, Gao, Fei, Rui & Kim, 2001) comb. n. (57, 58, after authors, not to scale). 55–58 male carapace (55 & 57 lateral view, 56 & 58 dorsal view), 51 right palp (retrolateral view), 52 palpal tibia and paracymbium (dorsal view), 53 suprategular apophysis (lateral view), 54 embolic division (ventral view). Abbreviations: E embolus, ED embolic division, R radix, SA suprategular apophysis. Diagnosis . The new species is closely related to Shaanxinus anguilliformis comb. n. described from Hebei Province by Xia et al . (2001) as Walckenaeria anguilliformis Xia, Zhang, Gao, Fei, Rui & Kim 2001 . The differences between these species are as follows: the new species is rather larger (length of S . anguilliformis ca 2.21–2.27, of S . rufus sp. n. ca 3.00–3.20); the shape of the palpal tibia (dorsal view) and of the head elevation: in the new species the head elevation is narrowed distally, being rounded in S . anguilliformis , and the clypeus in S . a nguilliformis is much wider than in S . rufus n. sp. (cf. Figs 55, 56 & 57, 58 ). Etymology : The specific name is derived from the Latin “ rufus ”, meaning red, referring to the reddish carapace; adjective. Description . Male. Total length––3.10. Carapace 1.55 long, 1.20 wide, brownish red. Head elevation large and high, directed anteriorly, narrowing distad, as in Figs 55–56 . All eyes situated on this elevation. Chelicerae 0,45 long, frontal surface near base slightly convex and serrated. Legs reddish yellow. Leg I, 4.55 long (1.30+0.40+1.25+1.05+0.55), IV––4.25 long (1.15+0.30+1.10+1.20+0.50). Leg II, 5.35 long (1.60+0.40+1.65+1.15+0.55), much longer than leg I. Ti and Mt I–II slightly curved. Chaetotaxy 2.2.2.2. Mt I–IV each with a trichobothrium. TmI––0.82. Palp ( Figs 51–54 ): Palpal tibia with a shallow and rounded hollow. Suprategular apophysis relatively short, flat, membranous apically and partly covering the embolic division. Radix with a large rounded outgrowth, its edge folded and forming a groove hiding distal half of embolus. Opisthosoma 1.70 long, 1.10 wide, pale grey, almost white, with two dorsal, median, wide, parallel, grey, interrupted stripes. Female. Unknown.
