Figs. 18–23 .

Material examined. Holotype male: Brazil, Santa Catarina, Grão Pará, P. E. Serra Furada (28o10’27’’S, 49o23’38’’W), 14.x.2012 – 16.xi.2012, malaise trap, LCP, LSG and ALS ( UNESP). Paratypes: same data as holotype, 1 male and 1 female ( UNESP), 1 male ( UFSC).

Description. Head mostly brown with portions of clypeus, lappets, and genae pale ( Fig. 18 ); clypeal area setose; post frontal line U-shaped; antenna and palpi pale. Pronotum dark brown with lighter rugosities ( Fig. 18 ). Legs with femora proximally yellowish, distally brownish; tibia and tarsi brownish. Wing membrane pale, with slightly less pigmented area, forming a window; veins pale. Cerci pale.

Male: Forewing length 9.0– 9.6 mm. Hammer truncate and wider than long ( Fig. 19 ). Penial armature robust, in ventral and dorsal views, narrowing abruptly apically ( Figs. 20–21 ); hooks regularly curved with apex pointed ( Fig. 21 ); pair of medium ventral vesicles present ( Fig. 21 ); keel elevated in lateral view ( Fig. 22 ).

Female: Forewing length 16.1 mm. Subgenital plate ochraceous, darker medially, and 4-lobed ( Fig. 23 ).

Remarks. The new species is unusual in its pale coloration, similar to that of A. petersi Froehlich (Froehlich, 2002) . However, the penial armature is more robust and differs from that of A. petersi .

Etymology. The name honors the Xokleng native people of the Macro-Ge language group, who inhabited southern Brazil, including the current State of Santa Catarina.
