Semomesia geminus (Fabricius, 1793) (Lepidoptera: Riodinidae: Mesosemiini): first records for Rio de Janeiro and Pernambuco states, range extension and distribution map, with an assessment of its potential wider occurrence in Brazil

Abstract

We report the first records of Semomesia geminus (Fabricius, 1793) from Rio de Janeiro (RJ) and Pernambuco (PE) states, expanding the known species range (Bahia-BA, Espírito Santo-ES and Minas Gerais-MG states) 700 km further south and 1200 km north of typical localities in ES. The taxon was photographed twice in Reserva Ecológica de Guapiaçu (REGUA) and two additional RJ specimens have since been located in museum collections. A distribution map build upon specimens’ label data is presented and a much wider range extension revealed and discussed. Observations on its perching habits, with potential taxonomic significance, are supplied.
