A revision of the Phelister haemorrhous species group (Coleoptera, Histeridae, Exosternini)
The Phelister haemorrhous species group is established here, revising the seventeen included species, four of which are described as new. This group is named for and contains the type species of Phelister, so represents a core around which a modern concept of the dumping-ground genus Phelister may be developed. The group includes several common and well-known species in the Americas, including some of the only Phelister to exhibit distinctive coloration. Several of these are typically found in cattle dung, and have likely expanded beyond their native ranges as cattle spread throughout the Americas. The group contains the following species: Phelister haemorrhous Marseul, 1854, Phelister affinis J.E. LeConte, 1859, Phelister parallelisternus Schmidt, 1893, Phelister mobilensis Casey, 1916, Phelister brevistriatus Casey, 1916, Phelister sonorae sp. nov., Phelister warneri sp. nov., Phelister puncticollis Hinton, 1935, Phelister subrotundus (Say, 1825), Phelister rouzeti (Fairmaire, 1850), Phelister rufinotus Marseul, 1861, Phelister thiemei Schmidt, 1889, Phelister parecis sp. nov., Phelister bryanti sp. nov., Phelister vernus (Say, 1825), Phelister chilicola Marseul, 1870, and Phelister bruchi Bickhardt, 1920. We also designate the following new synonymies: Phelister haemorrhous Marseul (= Phelister rubicundus Marseul, 1889, syn. nov.); Phelister subrotundus (= Phelister contractus Casey, 1916, syn nov.); Phelister rouzeti (Fairmaire) (= Phelister fairmairei Marseul, 1861; syn. nov., = Phelister wickhami Casey, 1916, syn. nov.); Phelister rufinotus Marseul, 1861 (= Epierus marseulii Kirsch, 1873, syn. nov.); and Phelister thiemei Schmidt, 1889 (= Phelister stercoricola Bickhardt, 1909, syn. nov.).
