Item The eyeless beetles of the genus Arianops Brendel (Coleoptera, Pselaphidae). Bulletin of the AMNH ; v. 154, article 1(New York : American Museum of Natural History, 1974) Barr, Thomas Calhoun, 1931-"The North American representatives of the tribe Amauropsini belong to a single known genus, Arianops Brendel, of which 31 species are recognized, arranged in seven species groups. Twenty-two species occur in the southeastern Appalachians, but other species are nown from central Pennsylvania (1), central Tennessee (3), north Alabama (4), and northwest Arkansas (1). Twenty-six species are edaphobitic, and five species, known only from caves, are probably troglobitic. The amplyoponica group includes amplyoponica (Brendel and Wickham), Pennsylvania; plectrops Casey, North Carolina; nodosa, new species, North Carolina; laminata, new species, North Carolina; spinicollis, new species, North Carolina; and sandersoni, new species, Arkansas. The alticola group includes two species from North Carolina, alticola, new species, and barbata, new species. The nantahalae group includes nantahalae nantahalae, new species and subspecies, North Carolina; nantahalae joanna, new subspecies, North Carolina; unicoi, new species, North Carolina and Tennessee; and digitata, new species, Tennessee. The neglects group includes neglecta, new species, North Carolina and Georgia; coweeta, new species, North Carolina; parki, North Carolina; truncata, Georgia; and allatoona, Georgia. The cavernensis group includes cavernensis Park, Alabama; jeanneli park, Virginia; stygica Park, Tennessee; pecki, new species, Tennessee; steevesi, new species, Alabama; extera, new species, Alabama; sewanee, new species, Tennessee; and kingi, new species, Alabama. The group is equivalent to subgenus Arispeleops Park, here considered a junior synonym of Arianops. The gigantea group is monobasic, established for gigantea, new species, North Carolina. The henroti group includes six small, flattened species from northeast Georgia and southwest North Carolina: henroti Park, Georgia; thornei, new species, North Carolina; norithe, new species, North Carolina; fovealis, new species, North Carolina; teyahalee, new species, North Carolina; and obliqua, new species, Georgia. A key to species, illustrations, and distribution maps are provided"--P. 3.Item The North American Pterostichus of the subgenus Cylindrocharis Casey (Coleoptera, Carabidae). American Museum novitates ; no. 2445(New York, N.Y. : American Museum of Natural History, 1971) Barr, Thomas Calhoun, 1931-"Cylindrocharis Casey, a subgenus of Pterostichus Bonelli, includes three species: P.(C.) rostratus (Newman), ranging from southeastern Canada to the southern Appalachian Mountains of Tennessee and North Carolina; P.(C.) acutipes, new species, from central Kentucky and Tennessee to the mountains of Tennessee and North Carolina, and northeast Georgia; and P. hypogeus, new species, from the Nantahala and Snowbird mountains, North Carolina. The central Kentucky populations of acutipes are described as a distinct subspecies, P.(C.)a. kentuckensis"--P. 13.Item Revision of Rhadine LeConte (Coleoptera, Carabidae). 1, The subterranea group. American Museum novitates ; no. 2539(New York, N.Y. : American Museum of Natural History, 1974) Barr, Thomas Calhoun, 1931-"The subterranea group of Rhadine LeConte includes 11 species, five of which are regarded as polytypic. The group is restricted to limestone caves in central Texas, and all its species are troglobites. Species and subspecies are: subterranea subterranea (Van Dyke), new status; subterranea mitchelli, new subspecies; russelli, new species; noctivaga, new species; austinica, new species; speca speca (Barr), new status; speca gentilis, new subspecies; speca crinicollis, new subspecies; exilis (Barr and Lawrence); persephone, new species; tenebrosa tenebrosa (Barr), new status; tenebrosa mckenziei, new subspecies; insolita, new species; infernalis infernalis (Barr and Lawrence); infernalis ewersi (Barr); koepkei koepkei (barr), new status; koepkei privata, new subspecies. Keys are provided for determining (a) species groups of Rhadine and (b) species and subspecies of the subterranea group"--P. [1].Item The taxonomy, distribution, and affinities of Neaphaenops, with notes on associated species of Pseudanophthalmus (Coleoptera, Carabidae). American Museum novitates ; no. 2682(New York, N.Y. : American Museum of Natural History, 1979) Barr, Thomas Calhoun, 1931-"Neaphaenops Jeannel includes one polytypic species, T. tellkampfi, from caves of the Pennyroyal plateau and adjacent upland in west-central Kentucky. Four subspecies are described and illustrated: tellkampfi tellkampfi (Erichson), t. viator, new subspecies, t. henroti Jeannel, and t. meridionalis Barr. A key to subspecies and a distribution map are given. It is suggested that Neaphaenops shares a close common ancestry with Pseudanophthalmus of the pubescens species group, and P. princeps, new species (Kentucky and Tennessee) may possibly represent an intermediate evolutionary stage. Taxonomic changes are proposed for Pseudanophthalmus ciliaris orlindae Barr, new combination, and P. loganensis Barr, new status"--P. [1].
