A new species of Lacosoma (Lepidoptera, Mimallonoidea, Mimallonidae) from Southern Brazil, and a new combination

Ryan A. St Laurent, Carlos C. G. Mielke


A new species in the genus Lacosoma Grote, L. horii sp. n., is described from a single male specimen collected in Paraná, Brazil. The holotype is deposited in the Collection of Padre Jesus S. Moure, Departamento de Zoologia, Universidade Federal do Paraná, Curitiba, Paraná, Brazil. This new species is potentially of conservation concern due to the fragmented nature of its habitat and extreme rarity in natural history collections. In examination of genitalia of numerous Lacosoma species for this and ongoing work, L. subrufescens (Dognin), comb. n. is recognized to belong in Lacosoma, and is hereby transferred from Trogoptera Herrich-Schäffer.
