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.
