A review of the genus Mirocastnia J. Y. Miller, 1980 (Lepidoptera: Castniidae) with records of recently collected specimens.

A new record of the rare species Mirocastnia pyrrhopygoides (Houlbert) from Ecuador is reported, along with range extensions for M. smalli (J. Y. Miller) and M. canis (Lathy). In addition, the genus Mirocastnia J. Y. Miller is revised and the diagnostic phenotypic characteristics of males and females, as well as male genitalia, are illustrated. Details on its natural history, biogeography, and biology are included with the purpose of solving the confusion in the taxonomy of the genus. All taxa previously considered to be species are herein relegated to subspecific status, i.e. M. pyrrhopygoides canis stat. nov. and M. p. smalli stat. nov.

A review of the genera Amauta Houlbert, 1918 and Divana J.Y. Miller, 1982 (Lepidoptera: Castniidae) with description of a new genus.

The genera Amauta Houlbert, 1918 and Divana J.Y. Miller, 1982 are revised, with discussion of diagnostic features of males and females of all taxa. Details on their nomenclatural history, biogeography, and biology are included to solve several nomenclatural issues. Lectotypes are designated for Castnia (Amauta) papilionaris affinis Rothschild, 1919 and Castnia tricolor C. Felder & R. Felder, 1874. The status of the following taxa is revised: Amauta procera (Boisduval, [1875]) stat. rest., Amauta angusta (H. Druce, 1907) stat. rest., Castnia ambatensis Houlbert, 1917 syn. nov. of Castnia papilionaris papilionaris Walker, [1865], Castnia velutina Houlbert, 1917 syn. nov. of Castnia papilionaris papilionaris Walker, [1865], and Castnia diva chiriquiensis Strand, 1913 syn. nov. of Castnia diva diva Butler, 1870. Other taxa are revised, and their taxonomic status clarified. A new genus Vadina gen. nov. is proposed for Castnia hodeei Oberthür, 1881, which is removed (comb. nov.) from Telchin Hübner, [1825], whilst Amauta stat. rest. and Divana stat. rest., subsumed into Telchin in the most recent revision of the family, are herein reinstated as valid genera.

Reinstatement of Athis miastagma (Dyar, 1925) (Lepidoptera: Castniidae) as a valid species inhabiting the Pacific slope of Central Mexico.

Mexico is the Mesoamerican country with the highest number of Castniidae species (12), most of which are found in the dry regions of the country. Among these, Athis hechtiae (Dyar, 1910) was considered a species widely distributed in Mexico after Athis miastagma (Dyar, 1925) was synonymized with A. hechtiae over two decades ago. A genetic and morphological study, as well as details of the natural history of various populations of these two taxa have led us to restore Athis miastagma as a valid species (stat. rest.), increasing the number of castniids recorded in Mexico to 13.

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 Hubner 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.
