Integrative description of two new species and two new subspecies of Lamprospilus Geyer (Lepidoptera: Lycaenidae)

Abstract

Lamprospilus stegmaier Prieto & Faynel sp. nov. is described from five specimens collected in sympatry with L. nicetus C. Felder & R. Felder on the northern central range of the Colombian Andes. Lamprospilus bicolor Faynel & Prieto sp. nov. is described from specimens collected in Colombia, Peru and Bolivia. Lamprospilus bicolor mirador Faynel & Prieto ssp. nov. is described from specimens collected in Peru and Bolivia. Lamprospilus decorata valluna Prieto & Faynel ssp. nov. is described from specimens collected in Western Colombia. Male and female phenotypes are associated, and we present morphological and molecular diagnostic characters for the new species. We also evaluate the congruence between a priori morphology-based species identifications and Molecular Operational Taxonomic Units (MOTUs) delimitations based on Barcode Index Numbers (BINs) in the genus. DNA barcodes are in perfect agreement with morphology in 64% of the species. Interspecific distances were found to range from 3.22% to 8.42% (average 5.48%), whilst their mean intraspecific variation ranges from 0.0% to 4.30% (average 1.78%). Based on DNA barcodes evidence of topotypic individuals, the study of original descriptions and illustrations of the holotypes, we consider here that Lamprospilus occidentalis Johnson & Salazar 2004 is a new junior subjective synonym of L. draudti Lathy, 1932.
