The Giant Lappet Moths (Lepidoptera: Eupterotidae) of Papua Indonesia

by Vadim Zolotuhin

An innumerous group presented in New Guinea only by four endemic genera and one genus shared with Australia. All genera were never revised; it is thought that Melanergon Bethune-Baker, 1904, Lasiomorpha Joicey & Talbot, 1916 and Rarisquamosa Bethune-Baker, 1910 are monotypic. The large and taxonomically very complicated genus Cotana Walker, 1865 comprises species with very prominent sexual dimorphism of which it is impossible to match both sexes together without rearing or molecular analysis. Thirty taxa were described based on male specimens and another eight are based on females; only two pairs are rather reliable known, therefore the taxonomic pattern of the genus will involve a lot of synonymy in the future.
The status of Eupterote acuminalba van Eecke, 1924, Nova Guinea, Vol. 15, p. 47 (pl. 1, fig. 10), described from Dutch New Guinea, is still unclear. Being described as a saturniid moth (Eurhodia lyda ssp.) it was later transfered to Eupterote but the genus is not native to Papuan Region. The type specimen is not found yet; the original image shows a moth similar to the Bombycidae (Elachyophthalma sp. of the cotanoides Roth. group).
The list (given alphabetically for species) is very preliminary, with very suspect combinations given, and strongly needs further study (in prep.).

Listed New Guinea species: 35 [some of the Cotana species likely to be synonyms being described due to sexual dimorphism]
