Pandava banna Lin & Li , sp. nov. ( Figs 63–65 )

Diagnosis. Males of the new species resemble all other Pandava species by the divided median apophysis and having the median lobe of the tibial apophysis longer than the retrolateral lobe. Females differ from other species by the long, coiled copulatory duct.

Description. Male (holotype). Total length 3.13. Carapace 1.53 long; 1.19 wide. Abdomen 1.52 long; 1.03 wide. Carapace brown with cephalic area dark brown. Chelicerae brown, with 3 promarginal and 2 retromarginal teeth. Sternum, labium and endites yellowish brown. Eye diameters and interdistances: AME 0.05; ALE 0.11; PME 0.11; PLE 0.10; AME– AME 0.04; AME–ALE 0.06; PME–PME 0.09; PME–PLE 0.12; AME–PME 0.10; ALE–PLE 0.08. Legs brown. Leg measurements: I 5.32 (1.56, 1.94, 1.20, 0.62), II 4.38 (1.34, 1.53, 0.99, 0.52), III 3.61 (1.17, 1.21, 0.82, 0.41), IV 3.52 (1.10, 1.18, 0.80, 0.44). Abdomen beige, with brown pattern.

Palp ( Figs 63–64 ). Median apophysis conical, bifurcated. Sperm duct visible in middle of tegulum. Prolateral lobe of tibial apophysis bifurcated, median lobe of tibial apophysis longest, terminus slightly curved, retrolateral lobe of tibial apophysis semi-circular with notch in the middle.

Female (IZCAS-Ar43336). Total length 4.13. Carapace 1.73 long; 1.25 wide. Abdomen 2.31 long; 1.25 wide. Chelicerae with 2 promarginal and 2 retromarginal teeth. Eye diameters and interdistances: AME 0.07; ALE 0.12; PME 0.11; PLE 0.12; AME–AME 0.05; AME–ALE 0.07; PME–PME 0.10; PME–PLE 0.13; AME–PME 0.10; ALE–PLE 0.04. Leg measurements: I 4.25 (1.31, 1.60, 0.75, 0.59), II 3.69 (1.26, 1.31, 0.66, 0.46), III 3.05 (0.93, 1.20, 0.53, 0.39), IV 4.00 (1.00, 1.01, 0.91, 0.48). Habitus similar to that of male.

Female genitalia ( Fig. 65 ). Epigyne with wide plate, long, coiled copulatory duct. Single elongate spermatheca. Fertilization duct transverse.
