Species delimitation in the Grayling genus Pseudochazara (Lepidoptera, Nymphalidae, Satyrinae) supported by DNA barcodes

The Palaearctic Grayling genus Pseudochazara encompasses a number of petrophilous butterfly species, most of which are local endemics especially in their centre of radiation in SW Asia and the Balkans. Due to a lack of consistent morphological characters, coupled with habitat induced variability, their taxonomy is poorly understood and species delimitation is hampered. We employed a DNA barcoding approach to address the question of separate...
