Arctiinae moths (Lepidoptera, Erebidae) of the Emas National Park, Goiás, Brazil

Abstract

Arctiinae are a species-rich subfamily of moth, with approximately 1,400 species in Brazil and 723 recorded in the Cerrado biome. A list of species of these moths was compiled during three years of sampling in four vegetation types within the Emas National Park. A total of 5,644 individuals belonging to 149 species were collected. About 67% of these species are new records for the Emas National Park, 31% for the State of Goiá s and 9% for the Cerrado biome. Cerrado sensu stricto and semideciduous forests have higher species richness, followed by campo cerrado and campo sujo. The vegetation type with the highest number of exclusive species was the semideciduous forest, followed by cerrado sensu stricto, campo cerrado and campo sujo. The high species richness and the high proportion of new species records for Goiá s and Cerrado reinforce the importance of the Emas National Park region as a center of diversity for this group of moths. The conservation of areas not yet cleared around the Park, including the creation of new protected areas, and the establishment of ecological corridors between these areas and the Park would be strategies to preserve the fauna of these moths. Resumo: Arctiinae é uma das subfamílias de mariposas mais ricas em espécies. Já foram registradas cerca de 1400 espécies no Brasil e 723 no bioma Cerrado. Uma lista de espécies destas mariposas foi compilada de três anos de amostragens realizadas em quatro fitofisionomias do Parque Nacional das Emas. Um total de 5.644 indivíduos, pertencentes a 149 espécies foram coletados. Cerca de 67% das espécies representam novos registros para o Parque Nacional das Emas, 31% para o Estado de Goiás e 9% para o bioma Cerrado. Cerrado sensu stricto e mata estacional semidecídua apresentaram maior riqueza de espécies, seguidas por campo cerrado e campo sujo. A fitofisionomia que apresentou maior nú mero de espécies exclusivas foi a mata estacional semidecídua, seguida por cerrado sensu stricto, campo cerrado e campo sujo. A grande riqueza de espécies e a alta proporc¸ão de novos registros de espécies para Goiás e para o Cerrado reforc¸am a importância da região do Parque Nacional das Emas como um centro de diversidade para esse grupo de mariposas. A conservac¸ão das áreas ainda não desmatadas no entorno do Parque, incluindo a criac¸ão de novas unidades de conservac¸ão, e o estabelecimento de corredores ecoló gicos entre essas áreas e o Parque seriam estratégias para preservar a fauna dessas mariposas.

Changes in Species Richness and Composition of Tiger Moths (Lepidoptera: Erebidae: Arctiinae) among Three Neotropical Ecoregions

“…Almost all previous studies of tiger moths in Neotropical South America were made at low latitude and focused on describing the species richness and composition and their responses to biotic and abiotic factors at a regional or local-scale [ 15 – 19 , 27 – 29 , 51 – 56 ], with some exceptions that encompass more than one ecoregion [ 20 , 57 ]. Furthermore, as far as we know no study until now has tested how the species richness and composition of tiger moths from Neotropical South America varies among regions at higher latitudes.…”

“…These two last sites were located in the Atlantic Forest biome and were intensively sampled. In the Cerrado sites, were recorded a much lower number of Euchromiina species, ranging from 11 (Scherrer et al 2013) to 30 (Moreno & Ferro 2016). Moreover, the number of Euchromiina species of a single Amazon site (Santarém, 96) was higher than the entire Cerrado Euchromiina fauna .…”

“…As observed for the subtribes Phaegopterina (Teston & Ferro 2016a), Pericopina (Teston & Ferro 2016b) and Ctenuchina (Teston et al 2019), the number of Amazonian Euchromiina species is underestimated because the fauna was never sampled in the vast majority of the biome (less than 10% of the municipalities were sampled). Even the sites already sampled need to be studied in the long-term (at least 1 year of sampling) because it is known that tiger moths respond to climate/seasonal changes (Kitching et al 2000, Hilt et al 2007, Scherrer et al 2013, Ferro et al 2014 and that Lepidoptera richness is higher in long-term surveys than in short-term surveys (Ferro & Diniz 2007, Moreno & Ferro 2016, Martins et al 2017. Moreover, studies that sample Amazonian Lepidoptera in different types and strata of vegetation are rare.…”

“…These values are similar to those found in well-sampled Atlantic Forest sites, as Boracéia, (10 species, Ferro & Diniz 2007) and Joinville (11, Ferro et al 2012). In the Cerrado well-sampled sites, however, were recorded only seven (Scherrer et al 2013) and six (Moreno & Ferro 2016) species of these three subribes.…”
