Male genitalia ( Figs. 130 , 186 , 242 ): Tuba analis shorter than width of valva. Socius with a process before middle on posterior margin, covered with one or two scale-like setae basally and two similar setae near apex, bearing two short setae apically; distal half covered with five to seven scale-like setae ( Fig. 242 ). Gnathos inflated distally, with three to four long thick setae apically. Valva oval, widest at middle; a row of long setae from base medially to distal area. Saccus longer than width of valva, with distal part narrowed, nearly linear. Phallus nearly straight, more sclerotized distally, about 8.0 times as long as width of valva ( Fig. 186 ). Second sternite with about nine micro-setae in each row; eighth sternite V or Y-shaped. Coremata present.

DNA sequences: Two COI barcodes were sequenced (one male and one female). The genetic distance is 0.3% between the two conspecifics, with interspecific genetic distances of 2.2̄2.6% between A. (A.) surrecta and A. (A.) lanosa , sp. nov. ( Table 2).

Distribution. China (Fujian, Guangxi, Guizhou, Henan, Hunan, Yunnan).

Diagnosis. The diagnosis is given under A. (A.) lanosa , sp. nov.

Etymology. The specific name is derived from the Latin surrectus, meaning nearly straight, referring to the nearly straight phallus as compared to the curved phallus of its congeners, A. (A.). angusta and A. (A.) lanosa , sp. nov.
