TL;DR: Gloora gen. nov. is established for Eucereon alba, Hyaleucerea mundula, Agaraea sericeum, and Gloora canae sp.nov, considering male genitalia in particular and, in case, barcodes.
Abstract: Gloora gen. nov. is established for Eucereon alba (Druce, 1894), Hyaleucerea mundula (Berg, 1882), Agaraea sericeum (Zerny, 1931), and Gloora canae sp. nov. These species are (re‑)described considering male genitalia in particular and, in case, barcodes. Further species which might fit into Gloora gen. nov. are discussed.
TL;DR: Following a general survey of the Neotropical Arctiinae using the so-called "barcoding" technique, three highly dimorphic females were identified and associated with their corresponding males.
Abstract: Following a general survey of the Neotropical Arctiinae using the so-called "barcoding" technique, three highly dimorphic females were identified and associated with their corresponding males. Idalus larissa Druce, 1890 comb. rev. is the male of Idalus albescens (Rothschild, 1909) syn. nov. Euplesia sphingidea (Perty, [1833]) is the male of Delphyre varians Hampson, 1901 syn. nov. and Apiconoma opposita (Walker, 1854) is the male of Delphyre aclytioides Hampson, 1901 syn. nov. Moreover two new species of the genus Apiconoma and one species of the genus Glaucostola , all collected in Brazil, are described: Apiconoma witti sp. nov. , Apiconoma mojui sp. nov. and Glaucostola indagata sp. nov. Several distances trees and pictures of all male (and one female) genitalia are provided. Distributions for all new species are discussed.
TL;DR: A new species and subspecies of Idalus Walker are described from Costa Rica, Honduras and Guatemala, with images of males and females and their genitalia provided.
Abstract: A new species and subspecies of Idalus Walker are described from Costa Rica, Honduras and Guatemala. Images of males and females and their genitalia are provided. Locality information and distribution maps for Costa Rica and for Guatemala are included. The biology and phylogeny of Idalus are discussed.
