( Fig. 7 ) Diagnosis. The species resembles A. staschi Jäger, 2012 by having a similar embolus and retrolateral tibial apophysis ( Fig. 7 ) but can be distinguished by the sharp terminus of the tegular apophysis ( vs. blunt in A. staschi ), by the sclerotized, triangular distal apophysis of the tegulum ( vs. absent in A. staschi ) and the patella of the palp has a distinct retrolateral apophysis ( vs. absent in A. staschi ). Description. Male ( holotype ). Colouration in alcohol: Carapace, legs and abdomen pale yellow. Chelicerae brown. Eye sizes and interdistances: AME 0.09, ALE 0.14, PME 0.08, PLE 0.13, AME–AME 0.03, AME–ALE 0.04, PME–PME 0.03, PME–PLE 0.12, AME–PME 0.05, ALE–PLE 0.03. Leg measurements: I 6.73 (1.68, 2.63, 1.48, 0.94), II 5.87 (1.53, 2.18, 1.28, 0.88), III 5.36 (1.38, 1.84, 1.34, 0.80), IV 7.55 (1.83, 2.49, 2.15, 1.08). Leg formula 4123. Chelicerae with 3 promarginal, 4 retromarginal teeth, without denticles. Tarsi and metatarsi without scopula. Palp ( Fig. 7 ). Retrolateral tibial apophysis projects at an almost right angle from tibia in ventral view, with 2 short apices. Patellar apophysis present. Cymbium tip slightly conical, prolateral cymbial bulge with distinct extension. Embolus arising at 9-o’clock-position from tegulum, with distinct membranous seam. Conductor arising at 12.30-o’clockposition from tegulum, bending retrolaterally. Tegular apophysis situated subcentrally on tegulum, terminus pointed. Female. Unknown. Material examined. Holotype ♂ (IZCAS-Ar43248), China : Guangxi , Hechi City , Huanjiang County , Dacai Township , Nuanhe Village , Longgong Cave ( 24.7738°N , 108.3856°E ), 15 January 2018 , Z. Chen leg. Distribution. Known only from the type locality. Etymology. The species name is a noun in apposition derived from the type locality.
