A review of the genus Insigniocastnia J.Y. Miller, 2007 (Lepidoptera: Castniidae) with notes on Castnia amalthaea H. Druce, 1890.

It is proposed that two little-known species of Castniidae which have been traditionally assigned to the genus Athis Hūbner belong to other genera; in addition, both have been found to have better-known junior synonyms. The statuses of the following taxa have been revised in this work: Castnia amalthaea H. Druce comb. rest., Castnia lecerfi Dalla Torre syn. nov., Castnia minerva R. Krüger syn. nov., Insigniocastnia bogota (Strand) comb. nov. and Insigniocastnia taisae J. Y. Miller syn. nov. A revision is presented for the genus Insigniocastnia J. Y. Miller. The female of I. bogota (Strand) has been unknown since its original description; it is herein described and illustrated for the first time.
