Diagnosis. Male of the new species is similar to A. hippocampa (Zhang et al. 2011: 5, figs 3A–C, 4D–F) in having a short embolus and a rounded bulb, but can be distinguished by the relatively short patella and tibia, the retrolaterally pointing patellar apophysis, the hooked RTA and the cymbial furrow longer than half of the cymbium ( Figs 1B–C View FIGURES 1 A – D , 2F–G View FIGURES 2 A – H ).
Description. Male holotype ( Figs 2A–D View FIGURES 2 A – H ): Total length 1.68. Prosoma 0.90 long, 0.68 wide; opisthosoma 0.88 long, 0.55 wide. Eye sizes and interdistances: AME 0.03, ALE 0.05, PME 0.04, PLE 0.05; AME–AME 0.02, AME–ALE 0.01, PME–PME 0.06, PME–PLE 0.04, ALE–PLE 0.04. MOA 0.12 long, front width 0.09, back width 0.14. Clypeus height 0.10. Leg measurements: I 2.61 (0.76, 0.85, 0.56, 0.44); II 2.46 (0.72, 0.77, 0.54, 0.43); III 2.23 (0.63, 0.69, 0.53, 0.38); IV 2.70 (0.75, 0.87, 0.65, 0.43). Leg formula: 4123.
