Arctiini Leach, [1815] (Lepidoptera, Erebidae, Arctiinae) of the Brazilian Amazon. IV - Subtribe Euchromiina Butler, 1876

Abstract: The Euchromiina moths comprise 735 species in the neotropics. Here we provide a list of Euchromiina species from the Brazilian Amazon. The list was produced from specimens deposited in the most important Brazilian collections and from literature data. Nearly 30% (219) of the neotropics Euchromiina species were recorded, including 13 new occurrences for the Brazilian Amazon. Santarém and Belém were the municipalities with the highest number of species records, with 96 and 74, respectively. Although the number of Euchromiina records is high in the Amazon, this value is underestimated because the fauna was never sampled in the vast majority of the biome. This is a worrying scenario because the Amazon has the world highest absolute rate of forest reduction. In order to suggest efficient conservation policies for the Amazon Arctiinae fauna, it is urgent to intensify the sampling effort in this biome.
