Diagnosis

This species is similar to A. hemitatos Park, 2017 superficially. It can be distinguished in the male genitalia by the uncus narrowed distally, the gnathos with a stout median process, and the juxta with a large median process ( Fig. 3F ); in A. hemitatos , the uncus is widened distally, the median process of the gnathos is narrowly elongate, and the juxta lacks a median process ( Park & Bae 2017: 287, figs 5‒6).

Apophyses posteriores slightly shorter than twice length of apophyses anteriores. Antrum weakly sclerotized, cup-shaped, spiculose. Ductus bursae longer than corpus bursae, twisted once anteriorly, with several thumbtack-shaped spines medially; ductus seminalis narrower than ductus bursae, helical, arising from about posterior ¼ of ductus bursae. Corpus bursae elliptical; signum situated at posterior 2/5, ovoid, serrate along margins, with a rectangular, horizontal central groove.

Distribution

Thailand (Nakhon Nayok Province) ( Park 2002); China (Fujian Province, Hainan Province, Jiangxi Province, Yunnan Province): new record.
