TL: Thailand . TD: ZMUC. 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).

FEMALE GENITALIA ( Fig. 4D ). Eighth abdominal sternite represented by two large lateral plates, grooved vertically along midline. 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. Remarks This species was originally described from Thailand based on three male specimens. In this paper, we newly record this species in China and describe its female for the first time.
