NMDS plot representing the morphometric analysis of dorsal male wings reflectance measurements of P. orphicus (orange dots) and P. lurae sp. nov (black dots). Stress = 0.02; specimens indicated in blue are potential P. lurae × P. orphicus hybrids collected in the contact zone and showed intermediate wing reflectance. Different symbols represent collection sites of three studied habitat with different substrate types (ophiolitic, karst, mixed). Ellipses represent 95% confidence intervals of specimen groups ‘orphicus’, ‘lurae’ and ‘hybrid’.
