Middle Carboniferous

Late Mississippian and earliest Pennsylvanian trilobite faunas of North America are dominated by the Paladin and Kaskia clades. Phylogenetic analysis of middle Carboniferous species of these clades demonstrates the close ancestral relationship between these groups. The Kaskia clade consists of eight species: K. chesterensis Weller, 1936, K. osagensis (Cisne, 1967), K. longispina (Strong, 1872), K. wilsoni (Walter, 1924), K. genevievensis (Walter, 1924), K. rosei (Cisne, 1967), K. gersnai n. sp., and K. rollinsi n. sp. Kaskia Weller, 1936 ranges from late Osagean to middle Chesterian (early Visean-early Serpukhovian) and is restricted to cyclothemic shelf and nearshore deposits. Species of Kaskia appear to have evolved in areas of shallow water and high environmental stress. The Paladin clade consists of 12 species including previously named species P. morrowensis (Mather, 1915), P. girtyianus Hahn and Hahn, 1970, P. rarus Whittington, 1954, P. helmsensis Whittington, 1954, and P. moorei (Branson, 1937). New species belonging to this clade are Paladin moorefieldensis n. sp., P. pleisiomorphus n. sp., P. imoensis n. sp., P. mangeri n. sp., and P. wapanukaensis n. sp. This group ranges from the early Chesterian to early Morrowan (late Viseanlate Bashkirian). Species of Paladin appear to be confined to outer shelf shelf-edge and off-shelf facies where presumably deeper water environments existed. This is manifested in their paleogeographic distribution, which is paleoenvironmentally controlled.

State Records

We present rearing records of Agromyzidae (Diptera) from five years of collecting throughout the United States. We review host and distribution data, and describe leaf mines, for 93 species, plus 28 others that could not be confidently identified in the absence of male specimens. We report 147 new host species records, including the first rearing records for Agromyza bispinata Spencer, A. diversa Johnson, A. parca Spencer, A. pudica Spencer, A. vockerothi Spencer, Calycomyza michiganensis Steyskal, Ophiomyia congregata (Malloch), and Phytomyza aldrichi Spencer. Phytomyza anemones Hering and (tentatively identified) Cerodontha (Dizygomyza) iraeos (Robineau-Desvoidy) are new to North America; Agromyza albitarsis Meigen, Amauromyza shepherdiae Sehgal, Aulagromyza populicola (Walker), Liriomyza orilliensis Spencer, Phytomyza linnaeae (Griffiths), P. solidaginivora Spencer, and P. solidaginophaga Sehgal are new to the USA. We also present confirmed USA records for Calycomyza menthae Spencer (previous records were based only on leaf mines), Ophiomyia maura (Meigen) (reported from the USA in older literature but deleted from the fauna in the most recent revision (Spencer & Steyskal 1986)), and Phytomyza astotinensis Griffiths and P. thalictrivora Spencer (previously only tentatively recorded from the USA). We provide 111 additional new state records. We describe the following 30 new species: Agromyza fission, A. soka, Melanagromyza palmeri, Ophiomyia euthamiae, O. mimuli, O. parda, Calycomyza artemisivora, C. avira, C. eupatoriphaga, C. vogelmanni, Cerodontha (Dizygomyza) edithae, Cer. (D.) feldmani, Liriomyza ivorcutleri, L. valerianivora, Phytomyza actaeivora, P. aesculi, P. confusa, P. doellingeriae, P. erigeronis, P. hatfieldae, P. hydrophyllivora, P. palmeri, P. palustris, P. sempervirentis, P. tarnwoodensis, P. tigris, P. triangularidis, P. vancouveriella, P. verbenae, and P. ziziae.

A New Species

Ants are one of the most successful and widespread organisms in the world. Although ants of the genus Pachycondyla (Hymenoptera: Formicidae: Ponerinae) are predominantly tropical in distribution, Pachycondyla chinensis (Emery) is especially abundant in temperate zones in Asia. Recently, P. chinensis has also become an abundant invasive ant species in the United States. However, it was well-known that the Pachycondyla chinensis species complex remained unresolved. Our molecular and morphological results allow us to distinguish two species in the species complex: the species P. chinensis and the new cryptic species P. nakasujii sp. nov., and these two species are widely and sympatrically distributed and abundant in temperate forests in Japan. Moreover, phylogenetic analysis showed that P. chinensis has been introduced into the United States from Japan. In conclusion, our finding of the new species P. nakasujii suggests that much remains undiscovered even in biologically fascinating and well-studied organisms.

AbstractAdults of Bandakia hoffmannae sp.nov., Bandakia mexicana sp.nov., Chappuisides notialis sp.nov., and Neoacarus adocetus sp.nov., all collected in the mountains west of Mexico City, are described. These are the first reports of species of these three essentially holarctic genera from south of the United States border in North America. These discoveries provide new insight concerning the extent of refugial areas for freshwater arthropods in southern North America during the Pleistocene.

AbstractThe Nearctic species of the genus Holoteleia are revised. Two named species are redescribed and five new species are described: H. armigera from Florida; H. coriacea, H. laticeps, and H. polita from eastern Canada and the United States; and H. elegans, widespread east of the Rocky Mountains. A diagnosis of Holoteleia and a key to the Nearctic species are given. Potential impact of environmental degradation on the frequency of Holoteleia species in North America is discussed.

A New Species

A new species of the ptilodontid multituberculate genus Prochetodon (Mammalia, Allotheria) from the Paleocene Paskapoo Formation of Alberta, Canada, is described. Prochetodon speirsae sp. nov. is the oldest discovered species of the genus, extending the temporal range of Prochetodon earlier into the Paleocene. It exhibits a mosaic of primitive and derived dental features suggestive of a position phylogenetically intermediate between Ptilodus and Prochetodon. Newly discovered specimens from the late Paleocene Gao Mine locality are referred tentatively to Prochetodon foxi. The occurrence of a primitive form of Prochetodon in sediments of early Tiffanian age suggests the evolutionary history of the genus is more complex than previously appreciated. Prochetodon joins a number of well-documented, progressive mammalian taxa making their first appearance in the Western Interior of North America at higher latitudes, well before their first known occurrence in the United States, suggesting a possible origin and immigration from currently unsampled habitats.

The genus Rhabdorthodesgen. n. is described for three previously unnamed noctuid moths from the mountains of south-western United States and Mexico. It is assigned to subfamily Noctuinae, tribe Eriopygini. Rhabdorthodespattersonisp. n. from the United States and Rhabdorthodesdurangosp. n. and Rhabdorthodespetersonisp. n. from Mexico are described. These moths are small, dull gray brown, and lack highly diagnostic wing markings, but are distinctive structurally. The adults and genitalia of both sexes are illustrated and distribution maps are presented. Two species eponyms honor persons who have facilitated the study and enjoyment of moths in North America by creating moth-specific websites.

A New Species

Several biologically significant domes of pachycephalosaurid dinosaurs are described and figured. One unusual specimen from the Oldman Formation (Upper Cretaceous) of Alberta is placed into a new genus and another specimen from the same formation is assigned to a new species of Stegoceras. Domes referable to Stegoceras sp. (Judith River and Hell Creek Formations) are the first conclusive evidence of the presence of this genus in the United States. A large dome from the Oldman Formation of Alberta is referred to Pachycephalosaurus; this specimen is the oldest described to date and is the first record of this genus in Canada.Endocranial casts of Yaverlandia bitholus and Stegoceras validus are described along with a discussion of endocranial trends in pachycephalosaurids. The separation between the cerebrum and cerebellum found in Yaverlandia, and typical of ornithopods in general, is lacking in Stegoceras and Pachycephalosaurus. The loss of this separation may be the result of head butting.The family Pachycephalosauridae possesses sufficient ornithopod characters to justify their retention in that suborder. It does, however, represent an aberrant side branch of ornithopod evolution, which can best be visualized taxonomically by placing this family into a separate infraorder within the Ornithopoda.

Among the shore crabs the genus Callianassa is quite cosmopolitan; its species are widely distributed and seem also to be peculiarly susceptible to parasitism. Wherever they have been examined carefully they have yielded semi-parasitic copepods, sometimes in considerable numbers. Such forms have been reported from both the east and west coast of North America, from the Mediterranean and from the British Isles. Recently 150 of these semi-parasites were sent to the United States National Museum from Salaverry near Trujillo on the coast of northern Peru. They were taken by Mr Floyd Sears, agent of the Grace Line at Salaverry, from the branchial chamber of a species of Callianassa on the Peruvian coast. They prove to be new species belonging to two genera of cyclopid copepods and are here described and figured.

Flies belonging to the genus Pseudochaeta are widely distributed in the United States and southern Canada but the allied genus Phaenopsis has not been recorded hitherto from North America. A recent study of the accumulated material in these genera has brought to light a number of distinct species, which are described below. I am especially indebted to C. F. W. Muesebeck, Dr. R. H. Beamer and A. R. Brooks for the loan of material. Types of the new species are in my collection.
