Phrurolithus zongxu sp. nov.

Figures 6 C, 10–11

Type material. Holotype male, China, Chongqing, Jinyun Mountain Natural Reserve: Yunhe Administrative Station, 29°50.5ʹ N, 106°21.5ʹ E, Alt. 248m, 4 December 2010, Z.X. Li leg. Paratypes: 3 males, 3 females, with same data as holotype.

Etymology. The specific name comes from the first name of the collector; noun.

Diagnosis. The new species is similar to P. hamatus sp. nov. ( Figs 6 B, 8– 9), but differs from the latter by the bifurcate RTA, the slender PTA and the short embolus of the male palp, and the small and widely separated copulatory openings and the broad posterior part of the bursae of female epigyne. In addition, the body size of the new species is usually smaller than that of the latter.

Description. Male ( Figs 11 A, 11C–D). Total length 2.19–2.21. Holotype total length 2.21. Prosoma 1.10 long, 0.91 wide; opisthosoma 1.09 long, 0.70 wide. Eye sizes and interdistances: AME 0.05, ALE 0.07, PME 0.05, PLE 0.06; AME–AME 0.02, AME–ALE 0.01, PME–PME 0.06, PME–PLE 0.06, ALE–PLE 0.04. MOA 0.15 long, front width 0.12, back width 0.13. Clypeus height 0.06. Chelicerae with 3 promarginal and 5 retromarginal teeth. Leg measurements: I 3.44 (0.96, 1.25, 0.80, 0.43); II 3.01 (0.85, 0.96, 0.74, 0.46); III 2.73 (0.71, 0.81, 0.70, 0.51); IV 3.92 (1.01, 1.18, 1.09, 0.64). Leg formula: 4123. Dorsum of opisthosoma with six bright chevron-like markings. Other shapes and coloration as same as P. h a m a t u s.

Male palp ( Figs 10 A–C, 11E–G). Femoral apophysis located ventrally. RTA bifurcate, the ventral branch sharper than the dorsal one. PTA thin and long, extending forward. Tegulum broad. Embolus short, located anteriorly, with an acute tip. Conductor small, membranous.

Female (one of paratypes, Figs 6 C, 11B). Total length 2.51. Prosoma 1.21 long, 1.03 wide; opisthosoma 1.32 long, 0.94 wide. Eye sizes and interdistances: AME 0.05, ALE 0.08, PME 0.05, PLE 0.05; AME–AME 0.03, AME–ALE 0.02, PME–PME 0.07, PME–PLE 0.06, ALE–PLE 0.05. MOA 0.17 long, front width 0.14, back width 0.15. Clypeus height 0.08. Leg measurements: I 4.09 (1.10, 1.48, 1.01, 0.50); II 3.32 (0.92, 1.18, 0.74, 0.48); III 3.04 (0.83, 0.98, 0.79, 0.44); IV 4.24 (1.11, 1.37, 1.08, 0.68). Leg formula: 4123.

Epigyne ( Figs 10 D–E, 11H–I). Copulatory openings small, located posteriorly, widely separated. Copulatory ducts with two large, transparent bursae. Spermathecae small, subtriangular, with small fertilization ducts anteriorly.

Distribution. Known only from the type locality of Chongqing, China ( Fig. 14 ).
