Distributional area of Eucereon ladas.

Eucereon ladas is a species described by Schaus, 1892 with habitat in Rio de Janeiro (state or municipality isn't clear in the given description). In the same work it was also provided a drawing that can be found here: https://archive.org/details/americanlepidopt00scha/page/n32/mode/1up?view=theater.

This drawing was initially compared with Inaturalist pictures filtered by Eucereon genus. Another comparison of pictures was done filtered by Arctiinae subfamily and subtribe as the lowest rank. The following areas was prospected with both filters: the brazilian states of Rio Grande do Sul, Santa Catarina, Paraná, São Paulo, Rio de Janeiro, Espírito Santo, Minas Gerais, Goiás, Mato Grosso do Sul and Distrito Federal; the argentinian provinces of Misiones and Corrientes; and Paraguay and Uruguay countries. Further comparison with suspected Eucereon ladas Inaturalist pictures was done with the BOLD Systems site: https://www.boldsystems.org/index.php/Taxbrowser_Taxonpage?taxid=645512.

A bibliographic search was done for the Eucereon ladas distributional area. Ferro, 2007 identified the species in Minas Gerais (Santa Bárbara) and São Paulo (Araras) states. The same work provided information of further know occurence areas of Eucereon ladas in the brazilian states of Rio de Janeiro, Paraná, Santa Catarina and Rio Grande do Sul but don't provided the municipalities where they was found. Ferro & Teston, 2009 (Rio Grande do Sul); Orlandin et al., 2016 and Silva & Silva, 2014 (Santa Catarina) and Nascimento et. al., 2016 (Rio de Janeiro) provided aditional data. The Paraná data was obtained by BOLDSystems public data: http://www.boldsystems.org/index.php/Public_RecordView?processid=LEMMZ052-10.

The coordinates data from Inaturalist (7 places) and bibliography (19 places) was ploted in a map using SimpleMappr site and resulted in Figure 1:

Eucereon ladas was found only in brazilian territory and can be endemic of Brazil. But the proximity with the argentinian province of Misiones of some occurrence places suggest caution and more data from that province will be necessary to confirm the brazilian endemism.
