Notes on Pachypasa otus and the description of a new Iranian Pachypasa species (Lepidoptera, Lasiocampidae, Lasiocampinae, Lasiocampini)

The synonymy between Pachypasa otus (Drury, 1777) and P. otus fulvescens Kotzsch, 1932 is supported by the lack of any stable morphologic characters and average distance of 0.3% in the cytochrome C oxidase (COI) gene between the Balkan (n = 4) and the Levantine (n = 2) populations. The Iranian population is described as a new species, Pachypasa hausmanni sp. n., based on morphologic difference, geographic isolation, and an average genetic distance of 6.1%.
