ABSTRACT Acanthospondylus pennsylvanicus, new genus and species, is described and illustrated on the basis of a single specimen from the Conemaugh Group (Late Pennsylvanian) of western Pennsylvania. Distribution and morphology of ossicles similar to those of Eospondylus primigenius Stürtz, 1886, from the Early Devonian of Germany, including the absence of radial shields, dorsal and ventral arm plates, and the relatively wide separation of laterals over the ambulacral groove, indicates that Acanthospondylus belongs to the family Eospondylidae (Oegophiurida, Zeugophiurina) along with Eospondylus Gregory, 1897, and Kentrospondylus Lehmann, 1957. This extends the range of Eospondylidae from Early Devonian (Siegenian and Emsian) to Late Pennsylvanian (Early Kasimovian [Missourian]).
ABSTRACT This paper describes a new African skipper, Procampta admiratio (Lepidoptera: Hesperiidae: Pyrginae: Tagiadini), inhabiting much of the Democratic Republic of Congo. It cannot be distinguished by external features from Procampta rara Holland, 1892, from Gabon, the Central African Republic, and West Africa. For 122 years the genus Procampta Holland, 1892, was thought to be a monotypic genus. The genitalia of the two species are very different and it was possible to confirm that those of the P. rara holotype were West African. On present knowledge the two species are wholly allopatric, though a specimen from Bangui, Central African Republic, is only 220 km north of the nearest P. admiratio.
ABSTRACT Fossil mammals comprising the early (and perhaps earliest) Wasatchian Red Hot local fauna from the Gulf Coastal Plain of Mississippi are described. As currently understood, the fauna consists of 33 species of mammals, including the following new taxa: Mimoperadectes sowasheensis, new species; Apatemys pygmaeus, new species; Palaeosinopa aestuarium, new species; Naranius americanus, new species; Colpocherus mississippiensis, new genus and species; Diacocherus dockeryi, new species; Wyonycteris primitivus, new species; Choctawius foxi, new genus and species; Haplomylus meridionalis, new species; Ectocion nanabeensis, new species; Miacis igniculus, new species; Eogale parydros, new genus and species; Viverriscus omnivorus, new genus and species; Paramys dispar, new species; Corbarimys? nomadus, new species; and Franimys? actites, new species. New combinations proposed here include Plagioctenodon dormaalensis (Quinet, 1964), Plagioctenodon rosei (Gingerich, 1987), Choctawius mckennai (Szalay, 1969), ...
ABSTRACT Four fossil rodent taxa are described from a new locality in the Oligocene Continental and Transitional Marine Deposits outcropping in the vicinity of Zallah, Sirt Basin, central Libya. These rodents belong to the infraorder Hystricognathi Tullberg, 1899, and are distributed amongst four genera (Metaphiomys Osborn, 1908; Phiocricetomys Wood, 1968; Talahphiomys Jaeger et al., 2010; and Neophiomys , new genus) that include one new species, Phiocricetomys atavus, and one new combination, Neophiomys paraphiomyoides (Wood, 1968), formerly Phiomys paraphiomyoides Wood, 1968. The specimens described here have profound implications for the phylogenetic and systematic status of early hystricognathous rodents and paleogeographical debates regarding their origin. Based on a cladistic analysis, Waslamys attiai Sallam et al, 2009, is transferred to the genus Protophiomys Jaeger et al., 1985, as Protophiomys attiai (Sallam et al, 2009), new combination. That species is the type species of the monobasic genus W...
ABSTRACT Two new species of crane flies in the genus Tipula Linnaeus, 1758, subgenus Emodotipula Alexander, 1966 (Diptera: Tipulidae: Tipulinae), are described from Taiwan and Thailand. Tipula (Emodotipula) lishanensis, new species, is the first representative of the subgenus known from Taiwan and is closely related to Tipula (Emodotipula) thailandica , new species, here described as the first species of that subgenus from Thailand based on characters of external male genitalia and on DNA-sequence comparisons. Illustrations of the diagnostic morphological features of the new species are provided.
ABSTRACT Diplodocus carnegii Hatcher, 1901, is a sauropod dinosaur that was originally recovered in the late 19th century in the Upper Jurassic of North America. The large amount of bones recovered permitted the reconstruction of the original skeleton at the Carnegie Museum in Pittsburgh, Pennsylvania, United States of America. A series of casts of the specimen were made and donated by Andrew Carnegie to different countries in Europe and Latin America. The cast of D. carnegii mounted in 1912 at the Museo de La Plata was one of the nine replicas donated by Carnegie. The history of the discovery, the trip to Argentina by Carnegie Museum personnel, and the mounting of the cast skeleton are related in this contribution.
ABSTRACT A new species of Anillinus Casey, 1918, is described from the Oak Ridge area, Roane County, Tennessee, in the eastern United States. Based on the presence of two patches with effaced microsculpture on the vertex, Anillinus inexpectatus, new species, belongs to the Anillinus loweae-group of species. Within this group, a patch of long setae on the ventral margin of the median lobe of the aedeagus places the new species close to Anillinus steevesi Barr, 1996. Modifications to a previous key for the A. loweae-group species are provided for identification of the new species, and zoogeographical considerations and biogeographical barriers for the A. loweae-group species are discussed.
ABSTRACT The taxonomic validity of the eryopid temnospondyl Glaukerpeton avinoffi Romer, 1952, from the Upper Pennsylvanian Conemaugh Group of North America is confirmed on the basis of a detailed restudy of two specimens: the holotype, based on a partial skull roof from Pittsburgh, Pennsylvania; and the skull and postcranial material of a second specimen from an approximately equivalent stratigraphie level in West Virginia that was originally referred to Eryops cf. E. avinoffi (Romer), but is reassessed here as G. avinoffi. This contradicts a previous redescription of the holotype of G. avinoffi as referable to Eryops Cope, 1882. A single unique feature, the presence of three large, fang-like tusks on the ectopterygoid, distinguishes Glaukerpeton from all other eryopids. A cladistic analysis was performed using 19 cranial and two postcranial characters to clarify the phylogenetic relationships between Glaukerpeton Romer, 1952, and the only other eryopids in which the skull anatomies are well known: the L...
ABSTRACT Taiwanese species of the crane fly subgenus Tipula (Acutipula) Alexander, 1924, are reviewed. Six species are recognized with two species being newly described: T. (A.) barbigeraand T. (A.) furcifera, both from Nantou. Tipula (A.) shirakii Edwards, 1916, previously considered a synonym of T. (A.) quadrinotata Brunetti, 1912, is recognized as a valid taxon. The female of T. (A.) kuzuensis Alexander, 1918, is described for the first time. DNA barcode sequences for 12 species of T. (Acutipula) are investigated and maximum likelihood trees resulting from the analyses are presented. The external anatomy of the last instar larva and pupa of T. (A.) shirakii is described and illustrated. Comments concerning the biology and habitats of larvae are presented. A taxonomic key is provided to identify all species recorded in Taiwan, and their distributions are briefly discussed.
ABSTRACT We present a reinterpretation of the bones previously identified as ossified hyoid elements in the Asian Late Cretaceous ceratopsian dinosaur Protoceratops andrewsi Granger and Gregory, 1923. Comparisons with other ceratopsian skeletons indicate that the tetraradiate bone tentatively regarded as a first ceratobranchial is actually an incomplete middle cervical rib, and the larger, flattened elements identified as second ceratobranchials are partial sternal plates. As in nearly all other ornithischian dinosaurs for which this area of the skeleton is known, the ossified hyoid apparatus of P. andrewsi probably consisted of a pair of rod-like first ceratobranchials; two additional, splint-like or sheet-like bones that are most frequently interpreted as ceratohyals may also have been present.
