Stag beetles of the genus Dorcus MacLeay in North America (Coleoptera, Lucanidae)
M.J. Paulsen
Abstract General confusion has surrounded the status of Nearctic Dorcus species since the 19th Century. In this paper the two Nearctic species are clarified and compared, and morphological characters discussed that will readily distinguish them. Examination of the type specimens of D. mexicanus reveals that they are actually mislabeled specimens and that the species is a new synonym of the Palearctic D. parallelipipedus (L.).
