Figs. 1–7

Material examined: Holotype male ( MZSP). BR, MG, São Gonçalo do Rio Preto, Parque Estadual do Rio Preto, small stream near park entrance (S18°5'43.10" W43°20'51.30"), 14.xi.2001, HP; Paratype. 1 female, same data as holotype ( MZSP).

Description: General color yellowish. Head yellowish with central part slightly darker ( Fig. 1 ); lappets ochraceous; clypeal area setose; two ocelli; postfrontal line U-shaped; antennae and palpi ochraceous. Pronotum yellowish with rugosities, sublateral bands ochraceous ( Fig. 1 ). Legs yellowish to ochraceous, tibia and tarsi darker. Wing membrane and veins pale. Cerci ochraceous.

Male: Forewing length 10.4 mm and total length 13.0 mm. Hammer truncate and wider than long ( Fig. 2 ). Penial armature in ventral/dorsal views ( Figs. 3–4 ) wide at the base and similarly wide at mid-length; presence of a constriction at the base of the apex ( Fig. 3 ) forming a short bottleneck and of a pair of medium sized ventral vesicles; hooks regularly curved with pointed tips; in lateral view ( Fig. 5 ), apex slightly bent dorsally.

Female: Forewing length 14.2 mm and total length 17.9 mm. Subgenital plate 4-lobed ( Fig. 6 ) with a deep medial notch ( Fig. 6 ). Egg measuring 0.295 x 0.250 mm ( Fig. 7 ).

Remarks: The penial armature of A. paprockii resembles that of A. uyara Froehlich 2002 , however differs by presence of a constriction at the base of the apex forming a short apical neck and by absence of a prominent keel (present in A. uyara ). Additionally, A. paprockii is lighter and smaller than A. uyara .
