AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

Twenty-three species of trilobites are recognized in the lower Mississippian Caballero and Lake Valley Formations of southern New Mexico. Species exhibit a segregation into shelf and off-shelf faunas, and can be subdivided into three distinct stratigraphic faunas. Species found in the Caballero Formation are similar to those found in the Chouteau Formation of Missouri. A second fauna, comprising species found in the Alamogordo, Nunn, and Tierra Blanca Members of the Lake Valley Formation, is correlated with the Fern Glen and Burlington Formations of Missouri. The third fauna found in the Arcente and Dona Ana Members of the Lake Valley Formation is correlated with the Warsaw and Salem Formations of the United States midcontinent region.Named species from the Kinderhookian Caballero Formation include: Dixiphopyge armata (Vogdes, 1891), Comptonaspis swallowi (Shumard, 1855), Brachymetopus indianwellsensis new species, Ameropiltonia perplexa new species, Griffithidella caballeroensis new species, and Kollarcephalus granatai new genus and new species. Named species from the Lake Valley Formation include: Pudoproetus fernglenensis (Weller, 1909), Breviphillipsia semiteretis Hessler, 1963, Griffithidella doris (Hall 1860), Phillibole planucauda (Brezinski, 1998), Piltonia carlakertisae new species, Australosutura llanoensis Brezinski, 1998, Thigriffides triangulatus new species, Thigriffides? alamogordoensis new species, Namuropyge newmexicoensis new species, Nunnaspis stitti new genus and new species, Hesslerides arcentensis new genus and new species, as well as an unnamed species of Proetides Hessler, 1962, Namuropyge Brezinski, 1988, and Thigriffides Hessler, 1965.

AbstractFrom the Santiago Ixtaltepec area, in Oaxaca State, southern Mexico, 11 species of productoid brachiopods, including a new genus and five new species, are described.Semicostellasp.,Antiquatoniasp.,Keokukia? sp.,Inflatia inflata,Reticulatiacf.R.huecoensis,Buxtonia websteri,Weberproductus donajiaen. gen. n. sp.,Dictyoclostus transversumn. sp.,Inflatia coodzavuiin. sp.,Buxtonia inexpletucostan. sp., andFlexaria magnan. sp. were collected from eight stratigraphic levels of the Ixtaltepec Formation. The presence ofSemicostellasp.,Keokukia? sp. andInflatia inflatain the basal strata, Units 1 to 3, of the formation indicate a Viséan-Serpukhovian (Late Mississippian) age.Reticulatiacf.R.huecoensisandBuxtonia websteri, found in Units 6 to 8, confirm the Pennsylvanian age for upper strata of the Ixtaltepec Formation.InflatiaandFlexariaare present in the uppermost beds of the formation so it is possible to extend their upper stratigraphic range to the Middle Pennsylvanian. All these taxa also occur in the United States Midcontinent, suggesting that during the Carboniferous the epicontinental sea extended at least to central Mexico.

In the Transactions of the Edinburgh Geological Society (vol. x, 1912, p. 49, pl. v, f. 8) I gave a figure of an Ichthyocrinid which occurred in No. 1 Bed, Invertiel, along with other members of the family, all of which were referred to ? Forbesiocrinus. In the spring of 1913 I had the pleasure of sending my specimens of flexible crinoids to the eminent crinoid authority, Dr. Frank Springer, of the United States Museum, Washington, who was then engaged on a comprehensive study of the group. For some reason or other I did not forward this particular specimen, probably because I did not think it well enough preserved (No. 939, Fig. 3 of present paper). The other Ichthyocrinids from Invertiel were referred by Springer to his new species Amphicrinus scoticus. It so happens that No. 939 was the only specimen of its kind which I had at that time cleaned and mounted in my collection, although as the sequel will show it is evident that I had found several others in the field, but had erroneously laid them aside as Amphicrinus scoticus. This is a mistake which could easily be made, since I was not then fully aware of the special characters which distinguished A. scoticus.

The composition of Permian members of the superfamily Subulitacea is considered, and 12 new species of Subulitacea are described from the silicified fauna of the Permian System of West Texas and New Mexico. Other elements of the gastropod fauna were previously described by Yochelson (1956a, 1960) and Batten (1958).The new genusIschnoptygmais established for subulitaceans possessing a plate-like columellar fold, and includes the new speciesIschnoptygma archibaldiandI. valentinei.The genus is placed within the new family Ischnoptygmidae. New species of Subulitidae areCeraunocochlis deformis, C. elongata, C. kidderi, C. trekensis, Strobeus girtyi, Soleniscus diminutus, S. variabilis, Cylindritopsis hamiltonae, andC. spheroides.The status of the genusLabridensis questioned, but provisionally retained. The assignment of the family Meekospiridae to the Subulitacea is questioned, and a single new species,Meekospira mimiae, is described.

Тhe agromyzid (Diptera: Schizophora: Agromyzidae) fauna of America north of Mexico is described in the first part of this publication, including a genus key and discussions on morphology, life history and classification. The second part is a species-level revision of the family in the “Delmarva” states of the United States of America, that is, of the District of Columbia and the surrounding states of Delaware, Maryland, Virginia and West Virginia. The fauna of this region includes 156 species. This study presents 346 new state and provincial records and 23 new country records, two of which are new continental records (Agromyza abiens Zetterstedt and A. apfelbecki Strobl). Liriomyza endiviae Hering is no longer considered to occur in North America. Fifteen species are newly described: Agromyza echinalissp. nov., Melanagromyza brunkeisp. nov., M. eoflacensissp. nov., M. glyptossp. nov., M. rutellasp. nov., Ophiomyia capitoliasp. nov., O. cupreasp. nov., O. galiodessp. nov., O. heleiossp. nov., O. kaliasp. nov., O. laticolissp. nov., Cerodontha (Poemyza) ungulasp. nov., Phytomyza avicursasp. nov., P. catenulasp. nov., and P. winklerisp. nov. Four new species-level synonyms and one genus-level synonym are provided: Agromyza marmorensis Spencer syn. nov. is included as a synonym of A. aristata Malloch; Melanagromyza fastosa Spencer, syn. nov. is included as a junior synonym of Ophiomyia tiliae (Couden); Melanagromyza verbesinae Spencer is considered a synonym of M. vernoniana Steyskal; Phytomyza ranunculoides Spencer, syn. nov. is included as a junior synonym of Phytomyza loewii Hendel; the genus Liomycina Enderlein, syn. nov. is included as a junior synonym of Phytobia Lioy. Ophiomyia ultima (Spencer), comb. nov. is recombined from Melanagromyza. Euhexomyza albicula Spencer, stat. reinst., comb. nov. is resurrected from synonymy with E. winnemanae (Malloch). New host records are given.

AbstractThe new genus Halegrapha is introduced, with six species (five new species and one new combination) from Australia, the Philippines, Malaysia, Kenya, Mexico, and the United States: H. chimaera Rivas Plata & Lücking (type species; Philippines), H. floridana Common & Lücking (United States: Florida), H. intergrapha Hale ex Lücking (Malaysia), H. kenyana Kalb & Lücking (Kenya), H. mexicana A. B. Peña & Lücking (Mexico), and H. mucronata (Stirt.) Lücking (Australia). The genus resembles Graphis morphologically in the strongly carbonized, black lirellae and white-grey thallus strongly encrusted with calcium oxalate crystals, but has a Phaeographis-type hymenium (clear in two species) and ascospores, making it a ‘chimera’ between the two genera. Molecular data suggest the genus to be closely related to Phaeographis and allies but genetically distinct from any of the genera currently recognized, including Platygramme.
