Abstract

Dasyophthalma includes five species of medium-sized butterflies, all endemic from the Atlantic Forest of Brazil. All known species are univoltine and are dayflying, differently from other Brassolini that are mostly crepuscular. In despite of recent advances little is known about their natural history. Three out of the five species are included in the Brazilian Red List of threatened fauna and are of conservation concern. The present study provides for the first time a phylogenetic assessment of all Dasyophthalma species based on a molecular approach based on three loci. Also, the taxonomic status of D. rusina delanira was revised based on molecular data. In addition, up-to-date distributional data and conservation aspects of the threatened species from the genus are presented and discussed. The molecular phylogenetic analysis supports the monophyly of Dasyophthalma, with Dynastor darius as its sister-group, and, combined with a genetic divergence analysis, supported Dasyophthalma delanira stat. rest. as a valid name to species-level, sister-group to D. geraensis (and not a subspecies of D. rusina). The geographical range (extent of occurrence and area of occupancy) for all five species are presented, showing that these are very restricted for D. delanira stat. rest. and D. geraensis, following the distributions of the high-altitude forests. As much biological information about the genus is lacking, the present study can serve as a starting point for future studies on Dasyophthalma, adding information that can be crucial for future conservation actions and essential to assure the future of the threatened species in this genus.
