Taxonomic history. Guenée (1877) described the species based on one female [recte male] [holotype] from Brazil without illustration. Transferred to Risama by Dalla Torre (1914) and returned to Siculodes by Whalley & Heppner (1995).

Taxonomic comments. Although known only from the holotype, the wing morphology and wing shape does not belong to Siculodes but rather to Aziba gen. rev., and therefore, A. mediula comb. nov. is a new combination.

Type material. The male [holotype] was found in the NHMUK, with the author’s original labels matching the information provided in the original description. Holotype male with the following labels: / Brés / 1. S Mediula Gn. Cat. n° Brésil / Siculodes mediula Brésil / Ex. Musaeo Ach. Guénée / Ex. Oberthür Coll. Brit. Mus. 1927-3 / Holotype / HOLOTYPE Siculodes mediula Guénee det. M. Shaffer, 1989 / NHMUK 010921219 /.

Diagnosis. Aziba mediula comb. nov. can be easily distinguished from all its congeners by wings overall dark gold, as the tegulae, wings overall dark gold, with small, clustered hyaline spots ( Fig. 8A–B ).

Redescription. Forewing: length—male 20.0 mm (n = 1); outer margin sinuous; retinaculum above costal margin; veins R 3 +R 4 bifurcates 3/5 of costal margin; clustering hyaline spots that condense, becoming more pronounced at outer margin.

Hindwing: length—male 13.0 mm (n = 1); outer margin rounded; clustering hyaline spots that condense, becoming more pronounced at costal margin up to near outer margin.

Male genitalia unknown.

Female unknown.

Geographic distribution. BRAZIL.

Natural history. Immature stages and host plant unknown.

Examined material (1 ♂).

BRAZIL: 1 ♂ ([Holotype] of Aziba mediula comb. nov.), NHMUK 010921219 ( NHMUK) .
