Holotype: SCAU, DIP 112280 , ♂ (4 June 2018).

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

Etymology: A combination of the Latin planus, meaning flat, and the ending - ceps (from princeps), meaning head, referring to the vertical lobe of the apically flat gonopod.

Diagnosis: This species is similar to A. cyclophylla in the vertical lobe of the gonopod, but can be distinguished from it by the shape of paramere with three lateral processes and aedeagus hook-shaped distally, with one pointed process medially ( Fig. 7E). In A. cyclophylla , the paramere has two lateral processes and the aedeagus bears no hook distally ( Fig. 4D).

Description

Male terminalia ( Fig. 7A–E): Epandrium entirely separated mid-dorsally, with ~17 setae near the posterior margin and one seta in the ventral lobe per side. Surstylus with no pubescence, with 11 long prensisetae on the distal margin, and several thin setae on the ventral margin and outer surface. The tenth sternite is bilobed, separated mid-dorsally, basally fused to the surstyli. Anterior portion of hypandrium entirely thin. Paramere lobe shaped, pointed apically. Aedeagus fused to the base of the parameres. Aedeagal apodeme strongly curved.
