Agelena injuria Fox, 1936 ( Figs. 19–24 )

Agelena injuria Fox 1936: 122 , fig. 2 (male holotype from Yao­Gi, Mupin , Szechwan [= Sichuan], China, 14 July 1929 and a male paratype from Tatsientu, 20 July 1923, USNM Cat. No. 1150, examined).

Additional material examined: China: Sichuan: Kangding (2560 m alt., 30°4’N, 101°57’E), 1 male, 7 females, 15 July 2000, M.S. Zhu et al. leg. ( MHBU) .

Diagnosis: The species is closely related to A. cuspidata sp. nov. ( Figs. 13 – 18 ), but can be distinguished from the latter by the narrow and blunt lateral tibial apophysis, the curved, strong conductor distal apophysis, and the small median apophysis of male palp; the small copulatory openings and the different positions of spermathecal apophyses of the epigynum.

Redescription of male: Male palp ( Figs. 22–24 ), with a wide patellar apophysis and two tibial apophyses. Lateral tibial apophysis small, with blunt tip. Tip of embolus cuspidal. Conductor with ventral, distal, median and dorsal apophyses and the distal one long, strong and curved ventrally. Median apophysis membranous, small and acute. For further details, see Fox (1936).

Description of female: Total length 13.67: prosoma 5.51 long, 3.98 wide; opisthosoma 9.28 long, 6.63 wide. Fovea longitudinal. Cervical groove and radial furrow distinct. Both eye rows strongly procurved, posterior row wider than anterior one. AME 0.30, ALE 0.25, PME 0.20, PLE 0.28. AME–AME 0.10, AME–ALE 0.15, PME–PME 0.30, PME– PLE 0.28. MOA 0.75 long, front width 0.70, back width 0.70. Clypeus height 0.75. Chelicerae with 3 teeth on each margin. Distal segment of posterior spinnerets much longer than basal one. Leg formula: 4123.

Measurements of legs:

Legs deep yellow. Dorsum of the opisthosoma brown, with four chevron­like grey markings. Spinnerets yellow.

Epigyne ( Figs. 20–21 ), with a big and slightly oval atrium. Copulatory openings visible. Copulatory ducts saccate, anterior part broad, gradually decreasing backwards. Spermathecal heads close to median line. Spermathecal stalks wide. Spermathecal apophyses present. Fertilization ducts situated behind spermathecal base.

Distribution: China (Sichuan).
