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.

Arctiini Leach, [1815] (Lepidoptera, Erebidae, Arctiinae) of the Brazilian Amazon. V - Subtribes Arctiina Leach, [1815], Callimorphina Walker, [1865] and Spilosomina Seitz, 1910

“…First, there was a great overlap in relation to the locations with the highest number of Arctiini species records. Belém, the capital of the state of Pará, was among the three most diverse locations in all Arctiini inventory papers (Teston & Ferro 2016a, b, Teston & Ferro 2019, Teston et al 2019a, this work), followed by Santarém (Teston & Ferro 2019, Teston et al 2019a, Cacaulândia (Teston & Ferro 2016a, Teston et al 2019a and Fonte Boa (Teston & Ferro 2016a, this work). This pattern was probably related to historical sampled effort (several naturalists sampled in the Amazon in the 19th and 20th centuries), and to the proximity/easer access to sampled sites and research institutions.…”

“…The tiger moth fauna was never sampled in the vast majority of the biome. The Legal Amazon comprises 775 muncipalities and there are sampled records in only 41 for Arctiina, Callimorphina and Spilosomina (this work), 48 for Pericopina (Teston & Ferro 2016b), 69 for Phaegopterina (Teston & Ferro 2016a), 71 for Euchromiina (Teston & Ferro 2019), and 75 for Ctenuchina (Teston et al 2019a). Besides, the sampling points are poorly distributed and usually restricted to more populated cities and along major rivers.…”

“…There are currently 1,023 Arctiini moths referred to the Brazilian Amazon, including 273 species of Ctenuchina (Teston et al 2019a), 219 species of Euchromiina (Teston & Ferro 2019), 62 species of Pericopina (Teston & Ferro 2016a) and 469 species of Phaegopterina (Teston & Ferro 2016b). However, it is still not certain how many species of the Arctiina, Calimorphina and Spilosomina subtribes exist in the Brazilian Amazon region.…”
