Figs. 11–16 .

Material examined. Holotype: male: BR, GO, Cidade de Goiás, Fazenda Ferreirinha, 04.x.2003 ( UNESP). Paratypes: 4 males, 6 females, same data of holotype ( UNESP).

Description. Male forewing length 8.1–8.3 mm, female 11.6–12.2 mm. General color light brown. Head light brown with M-line, area laterally to ocelli and clypeal area lighter, area between ocelli darker ( Fig. 11 ); gena and parietalia yellowish; lappets brown ( Fig. 11 ); clypeal area setose; postfrontal line U-shaped; antenna brownish; maxillary palps brownish; the two first segments of labial palps ochraceous, the last segment brownish. Pronotum brownish, darker laterally ( Fig. 11 ). Legs, femora ochraceous to brownish, tibia and tarsi brownish. Wing membrane and veins brownish with the presence of a distal less pigmented circular area forming a window. Cerci brownish. Male. Hammer a truncate cone ( Fig. 12 ); penial armature slightly cylindrical, in dorsal view narrowing abruptly apically ( Fig. 13 ), in lateral view apex expanded dorsally ( Fig. 15 ); hooks relatively large, regularly curved and with apex pointed ( Fig. 14 ). Female. Subgenital plate 4-lobed ( Fig. 16 ); sternum 9 with fields of hairs forming a "T", with longer and stronger hairs at the margins. Egg oval, 0.295 x 0.195 mm.

Remarks. The penial armature of A. corae is similar to A. toriba Froehlich (Froehlich, 2002; 2010). However, A. corae is smaller and has a wing with less pigmented spot forming a window. Additionally, the female subgenital plate is 4-lobed (bilobed in A. toriba ) and has a less elongated egg.

Etymology. The patronym honors Cora Coralina, pseudonym of Ana Lins dos Guimarães Peixoto Bretas (1889–1985), who was an important poet born in Goiás City (Goiás State), region where the specimens were collected.
