Resumo

The riodinid Eucorna sanarita (Schaus) is an "Endangered" (EN) butterfly with a confusing taxonomic history, restricted to a few sites of montane forest in the Atlantic Forest biodiversity hotspot, Southeastern Brazil. This study aims to collate all previous and novel available information for this species, such as systematic position, taxonomic placement, and geographic distribution, and to identify potential areas of occurrence using niche-based models. Ecological niche modeling (ENM) and geographical range (area of occupancy (AOO) and extent of occurrence (EOO)) were estimated using a total of 14 known geographic sites for this taxon. Until recently, this species was included in the genus Voltinia Stichel, 1910, and based on molecular data, we find that it is sister to the recently reassigned Napaea Hubner, [1819]. Predictive maps generated from niche models extend the possible sites of occurrence and aid in EOO and AOO estimation, both of which are important in the application of IUCN assessments. Our findings can be applied to the identification of additional sites for populations of E. sanarita and possibly resolve its conservation status (based on geographical range). Implications for insect conservation Our study contributes to the filling of knowledge gaps in the ecology, systematics, and taxonomy of E. sanarita, an endemic butterfly to the Atlantic Forest biodiversity hotspot, and brings a new perspective on the use of ENM to AOO and EOO estimates that can directly inform the conservation status of the species following IUCN guidelines.
