Anacroneuria iguazu n. sp.

Figs. 20–24 .

Material examined. Holotype: male: BR, PR, Foz do Iguaçu, 07.xii.1966 ( DZUP). Paratype; 1 male, BR, PR, Campo Largo (Estrada do Cerne Km 40), 07.xii.1974 ( DZUP).

Description. Forewing length 11.5–13.9 mm, total body length 14.6–16.7 mm. General color brownish. Head brownish with M-line, parts of clypeal area, frons and laterally to ocelli brownish ( Fig. 20 ); lappets brown; clypeal area setose; postfrontal line U-shaped; scape and pedicel brown; flagellum brownish; palpi yellowish. Pronotum brownish with lighter rugosities ( Fig. 20 ). Legs brownish, tibia and tarsi darker. Wing membrane brownish, veins brown. Cerci brownish. Hammer truncate, wider than long ( Fig. 21 ). Penial armature narrowing gradually from base to apex in ventral/dorsal views ( Figs. 22–23 ), apical third strongly bent ventrally in lateral view ( Fig. 24 ); hooks regularly curved and directed dorsally, passing above the body of the penial armature; pair of large ventral vesicles present; keel slightly elevated in lateral view.

Remarks. The forewing length and color of this species are similar to several species. In dorsal and ventral views, the penial armature resembles those of A. flintorum ( Froehlich, 2002) and A. ofaye (Froehlich, 2007) . However, in A. iguazu , the hooks extend above the penial armature, which is strongly curved ventrally, differing from the other species of the genus.

Etymology. the name makes reference to Foz do Iguaçu, region where the holotype was collected.
