Lepidoptera Erebidae Arctiinae


During several days of entomological expedition, as part of a thesis on the phylogeny of Phaegopterina, the first author collected in Northwestern Argentina (provinces of Jujuy and Salta) a series of Mazaeras species previously treated as Mazaeras janeira (Schaus, 1892). The second author, after an expedition in the southern Bolivia (departments of Chuquisaca and Santa Cruz), had a series of specimens of the same taxon also identified as M. janeira (Schaus, 1892). Examination of the male genitalia of the Argentinean specimens showed several differences with the male genitalia of the lectotype of M. janeira. Molecular analysis with specimens of the two taxa confirmed the discrimination. The new species is described and a comparison based both on morphological characters and DNA barcodes with closely related species is provided. The new species can be found in northwestern Argentina (Salta and Jujuy provinces) and southern Bolivia (Santa Cruz, Chuquisaca and Tarija departments) in Yungas montane forest. Mazaeras yungasensis n. sp. can be found between 467m to 2540m (data from Instituto Fundación Miguel Lillo (IFML), Museo de La Plata (MLP), Museo de Zoología de la Universidad Nacional de Córdoba (MZUC) and personal collection: Benoit Vincent (BVC) and Michel Laguerre (MLC) (Fig. 11).
