Taxonomic history. The genus was described based on two species: Aziba transversa Walker, 1865 and Aziba reticula (Guenée, 1858) . Guenée (1877) synonymized Aziba with Siculodes .

Taxonomic comments. We concluded that Aziba transversa is distinct concerning the characters of Siculodes after examining the wing morphology and genitalia of both sexes of the type species of Siculodes ( S. aurorula) and Aziba gen. rev. ( A. transversa) and therefore is herein revalidated.

Diagnosis. See diagnosis for Siculodes .

Redescription. Thorax: labial palps larger than width of thorax; spots or defined lines on ventral surface on both wings; forewing with branch R parallel and close to Sc, separating into R 1 and Rs when reaching 2/5 of Sc and disc cell. Rs divided into following branches: R 2, R 3 +R 4 and R 5; branch R 3 +R 4 bifurcates at different distances, R 2 and R 3 reaching costal margin, R 4 reaching apex and R 5 ending at external margin, apex pointed similar to a half moon, and outer margin sinuous, less pronounced in females; frenulum and retinaculum only in A. falcata and A. mediula, absent in other species; metathoracic tibia with four long spurs.

Male genitalia: tegumen wider than long; uncus triangular and with pointed apex directed ventrally, base as wide as tegumen, lateral margins covered by short, fine bristles; gnathos narrow and sclerotized, projected postero-ventrally; valva longer than wide and with bristles on inner surface, narrowing obliquely from distal half, costa straight (except in A. vehemensaria), apex rounded, sacculus rectangular; fultura inferior with short, fine bristles; aedeagus cylindrical with dorsal opening for ductus ejaculatorius.

Female genitalia: tergite VIII square or rectangular in lateral view; lamella antevaginalis and ostium membranous; antrum sclerotized and remaining of ductus bursae membranous; corpus bursae globose and well distinct from ductus bursae; and papilla analis wider than long, covered in long, fine bristles.
