SCAU, DIP 112287 , 88 , two ♂ (6 May 2016). China: Mengdong, Cangyuan , Yunnan, 23°10′18″N, 99°13′20″E, elevation 1323 m, L. Zhu, Y.L. Wang .

Etymology: Named in honor of Dr Xing-Lai Ji (Yunnan University, China).

Diagnosis: This species slightly resembles A. gaoi in the male terminalia, but can be distinguished from it by the paramere being pubescent, apically thin and basally expanded; aedeagus slender, distally strongly curved, with several serrated processes submedially and subapically ( Fig. 11D, E). In A. gaoi , the paramere has no pubescence, and is thick, finely serrated on apical margin; the aedeagus is basally thick, distally slender, medioventrally with one small, triangular projection (as shown by Zhang & Chen, 2006: figs 2, 3).

Description

Male terminalia ( Fig. 11A–E): Epandrium constricted more than half width mid-dorsally, with ~13 setae near posterior and ventral margins per side. Surstylus entirely pubescent, with three aristate processes on mesal surface, nine long prensisetae on distal margin and a finger-like process at posteroventral corner. Anterior portion of hypandrium entirely thin. Paramere subbasolatrally with approximately eight sensilla. Aedeagal apodeme strongly curved.
