Chrysso dentaria sp. nov. ( Figs 23–25 )

Holotype ♂, China, Yunnan, Xishuangbanna, Menglun , teak plantation (21º54.770'N, 101º16.084'E), 12 November 2006, Guo Tang and Zhi-Yuan Yao leg.

Etymology. The specific name derives from the Latin adjective dentarius and means “of teeth”, in reference to the embolus with a dentate apophysis.

Diagnosis. The new species is very similar to C. vitra , but can be distinguished by the embolus stronger than in the latter species, with a basal apophysis.

Male. Total length 1.13. Prosoma 0.58 long, 0.50 wide, high, pale, with black stripes. Sternum 0.28 long, 0.30 wide, pale. Opisthosoma 0.60 long, 0.60 wide, pale, with white spots, 5 apophyses, without colulus. Eye measurements: AME 0.08, ALE 0.06, PME 0.06, PLE 0.06, AME-AME 0.06, AME-ALE 0.03, PME-PME 0.06, PME-PLE 0.03. Clypeus height about 1.67 times AME diameter, pale. Chelicerae: pale yellow, without tooth; fangs short, slender. Endites: 0.13 long, 0.06 wide, pale with long setae, brown pro-edges. Labium fused with sternum, 0.05 long, 0.09 wide, with 2 setae, pale. Leg measurements: I 2.83 (0.80, 0.20, 0.48, 0.94, 0.41); II 1.93 (0.64, 0.19, 0.31, 0.50, 0.29); III 1.45 (0.43, 0.19, 0.30, 0.25, 0.28); IV 2.23 (0.75, 0.19, 0.43, 0.55, 0.31). Leg I coxa yellow, with black spot; femur-tarsus pale, with black rings; femur without spine; patella with 1 distal spine, 1 basal spine; tibia with 2 rhombic spines; metatarsus and tarsus
