Ginungagapus tangerinii Carneiro, Mielke & Casagrande sp. nov.

( Figs 5 , 13 , 20 and 24 )

Diagnosis. Very similar to G. bocus comb. nov. with respect to the characters mentioned in its diagnosis. It is distinguished from it by a reduced forewing size, less produced harpe, ovoid lateral expansion of lamella postvaginalis and posterior margin of sterigma with larger lateral projections, separated by a V shaped concave margin.

Description. Forewing length: 13–14,5. Nudum 12. Palpus ventrally light brown. VHW costal area red ferruginous, from base to Sc end; subapical spot fainted; central and discal areas delimited between well marked bands, light brown or bluish. Male genitalia: median posterior projection of tegumen developed, fenestra triangular, longer than wide. Uncus bifid, arms projected, closely separated at the base. Valva with triangular sacculus; harpe posteriorly rounded with a ventro-posterior spined curved line on inner surface contiguous with harpe's border. Ampulla undistinguished. Coecum of aedeagus lobed, laterally straight. Aedeagus dorsally with median membranous hollow; posterior lobes developed, asymmetrically rounded; vesica proximally lightly sclerotized, wide; cornuti as small triangular aligned spines. Fultura inferior dorsally projected over aedeagus but not joined in an annellus, dorsally thin and straight. Female genitalia: lateral expansion of lamella postvaginalis ovoid. Posterior margin of lamella postvaginalis with pointed lateral projections separated by a V shaped concave margin. Ductus bursae sclerotized from the sterigma to the fold, without sclerotized strucuture within. Corpus bursae with large lateral signa.
