urn:lsid:zoobank.org:act:412B46C8-C68F-4BF3-9D03-F6C299FADEFA

Holotype: SCAU, DIP 112281 , ♂ (4 June 2018).

Type locality: China: Gexigou, Yajiang , Sichuan, 30°02′32″N, 100°59′04″E, elevation 2800 m, L. Gong GoogleMaps .

Etymology: From Latin scrobiculus, diminutive of scrobis, meaning a ditch or trench, referring to the vertical lobe of the apically concave gonopod.

Diagnosis: This species is similar to A. jizushanensis in the male terminalia, but can be differentiated from it by the surstylus being pubescent medially, and the tenth sternite with a lateral lobe-like process somewhat oblong, narrowly fused to surstyli ( Fig. 8B); paramere lateral two processes developed. In A. jizushanensis , the surstylus is lacking a pubescence on the outer surface; the tenth sternite has no lateral lobe-like process; and the paramere lateral processes is less developed (as shown by Chen et al., 2005: fig. 15D).

Description

Male terminalia ( Fig. 8A–D): Epandrium entirely separated mid-dorsally, with ~17 setae near posterior and ventral margins per side. Surstylus with five or six long prensisetae on distal margin, and several thin setae on ventral margin and outer surface. Anterior portion of hypandrium entirely thin. Paramere lobe shaped, pointed apically, with seven sensilla medially. Aedeagus separated into a pair of simple rods, each partly fused to the base of the parameres. Aedeagal apodeme strongly curved.
