AbstractThe Nearctic species of Dicraeus Loew (Diptera: Chloropidae) are revised. Eight species are recognised in North America: Dicraeus curtisinew species is described from the western United States of America; the Palaearctic species D. vagans (Meigen) is newly recorded in North America; D. elongatus Sabrosky; D. fennicus Duda; D. incongruus Aldrich; D. ingratus (Loew); D. tibialis (Macquart); and D. wilburi Sabrosky are redescribed. All species are described and illustrated and a key to species is provided. Dicraeus aberrans Sabrosky, described from New Mexico, United States of America, is transferred to the genus Notaulacella Enderlein as Notaulacella aberransnew combination. This represents the first Nearctic record of the previously Neotropical genus Notaulacella.

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.

AbstractNearctic Stylogaster Macquart (Diptera: Conopidae) species concepts are revised. We provide redescriptions of S. biannulata (Say) and S. neglecta Williston, description of S. beresfordinew species, an illustrated key to species, range maps, and ecological data. Stylogaster beresfordi ranges from southern Mexico to southern New Mexico, United States of America. DNA barcode data are provided with neighbour-joining and Bayesian analyses and relationships of the three species are discussed. We hypothesise that S. neglecta and S. beresfordi are sister taxa, while S. biannulata is in a different clade.

AbstractIn midcontinent North America, the Fox Hills Formation (Upper Cretaceous, upper Maastrichtian) preserves the last marine faunas in the central Western Interior Seaway (WIS).Neritoptyx hogansoninew species, a small littoral snail, exhibited allometric change from smooth to corded ornament and rounded to shouldered shape during growth. Specimens preserve a zig-zag pigment pattern that changes to an axial pattern during growth.Neritoptyx hogansoninew species was preyed on by decapod crustaceans, and spent shells were occupied by pagurid crabs. Dead mollusk shells, particularly those ofCrassostrea subtrigonalis(Evans and Shumard, 1857), provided a hard substrate to which they adhered on the Fox Hills tidal flats. This new neritimorph gastropod establishes a paleogeographic and chronostratigraphic proxy for intertidal conditions on the Dakota Isthmus during the late Maastrichtian. Presence of a neritid extends the marine tropical/temperate boundary in the WIS northward to ~44° late Maastrichtian paleolatitude. Late Maastrichtian closure of the isthmus subsequently altered marine heat transfer by interrupting northward flow of tropical currents from the Gulf Coast by as much as 1 to 1.5 million years before the Cretaceous ended.UUID:http://zoobank.org/3ba56c07-fcca-4925-a2f0-df663fc3a06b

Significant Underestimation

The endemic North American stag beetle tribe Platyceroidini Paulsen & Hawks (Coleoptera: Lucanidae: Lucaninae) is reviewed. All primary types were studied and the existing generic and species concepts are subsequently corrected. Based on study of the male genitalia and external morphology, the previously monotypic genus Platyceropsis Benesh is reduced to subgeneric status under Platyceroides Benesh, new status, and the species Platyceroides laticollis (Casey) and Platyceroides keeni (Casey) new combination are transferred to this subgenus. Praocerus, new subgenus, is created to contain the species Platyceroides latus (Fall), and P. viriditinctus (Benesh). In the nominal subgenus, confusion has resulted from the historic misapplication of the oldest available name, Platyceroides agassii (LeConte), resulting in significant underestimation of the number of extant taxa. Lectotypes are designated for four species-group names (listed in their original combinations): Platycerus latus Fall, Platycerus opacus Fall, Platycerus pacificus Casey, and Platycerus parvicollis Casey. Four new species (Platyceroides barrae, P. infernus, P. pampinatus, and P. umpquus) are described from California and Oregon, United States of America. The following species are valid and are removed from synonymy with P. agassii: P. pacificus (Casey), revised status, and P. californicus (Casey), revised status. The synonym Platycerus parvicollis Casey is transferred from Platyceroides agassii to P. californicus, new synonymy. With the addition of four new species and the correction of the mistaken synonymies the total number of species in the tribe Platyceroidini is now 16.

AbstractSix new species of Mucroseius having adult females phoretic on adult sawyer beetles of the genus Monochamus are described: Mucroseius nipponensis and Mucroseius squamosus from Monochamus alternatus Hope in Japan, Mucroseius algonquian from three species of Monochamus in eastern Canada and eastern United States, Mucroseius disparisetus from Monochamus titillator (Fabricius) in southeastern United States, Mucroseius Californicus from Monochamus clamator (LeConte) in California, and Mucroseius mexicanus from Monochamus rubigineus (Bates) in Mexico. Mucroseius aciculatus (Ishikawa, 1968), new combination, from Mecynippus pubicornis Bates in Japan, and the type-species, Mucroseius monochami Lindquist, 1962, from several species of Monochamus widely distributed in North America, are redescribed. Misidentifications of these species in the Japanese and North American literature are noted, and a key is given for these eight species. One adult female of an undescribed species found on a sawyer, Monochamus sutor Linnaeus, from Europe, is noted as possibly belonging to Mucroseius.The taxon Mucroseius is redescribed, and its problematic status as a genus is reviewed. The phylogenetic position of Mucroseius, which appears to be derived within the genus Proctolaelaps, is discussed. Previous observations on biological and ecological aspects of Mucroseius mites, including those published in Japanese, are critically reviewed, with new data added for host ranges and specificities, distribution, phoretic behavior, occurrence in sawyer gallery systems, mode of reproduction, and their association with the pine wood nematode, Bursaphelenchus xylophilus (Steiner and Buhrer) Nickle. Cheliceral structure and speculations on the feeding habits of these mites are discussed; however, feeding preferences have not been clarified.

Terrestrial Gastropod

The remaining terrestrial gastropod fauna of the late Oligocene–early Miocene Cabbage Patch beds of western Montana is composed of nine new species, all from extant genera now occurring in the western United States: Vallonia berryi, [Succineidae] montana, Nesovitrea pulchra, Deroceras securis, D. mahiz, Punctum alveus, Polygyroidea montivaga, Oreohelix brandi, and Monadenia? n. sp. A, which is described from neanic material. All except the Monadenia? represent first occurrences of the respective genus in North America. The terrestrial fauna suggests that climatic and environmental conditions during the late Oligocene–early Miocene interval must have been very similar to those of the present. Two sizes of gastropod eggs, attributed to P. montivaga and V. berryi, were found at one locality. Monadenia? n. sp. A is of limited use, due to rarity, as an index fossil for the upper Cabbage Patch beds.

Late Cambrian

Nine agnostoid species from late Cambrian (Paibian: Steptoean) boulders from the Cow Head Group in western Newfoundland fall into three biostratigraphically distinct faunas. The Glyptagnostus reticulatus Fauna contains only the eponymous species and correlates with the lower part of the Paibian and the basal Steptoean of North America. The “Innitagnostus” inexpectans Fauna is more diverse and likely correlates into part of the lower Steptoean Aphelaspis Zone of western North America. The youngest fauna, the Acmarhachis kindlei n. sp. Fauna, also includes species of Homagnostus and Pseudagnostus, as well as a second new species of Acmarhachis, A. whittingtoni. It probably correlates with the Dunderbergia Zone (mid-Pabian and mid-Steptoean) of the western United States. The Laurentian species Acmarhachis typicalis Resser (1938) and A. acuta (Kobayashi, 1938) are evaluated from restudy of type material, and types of “Innitagnostus” inexpectans (Kobayashi, 1938) from British Columbia are also reillustrated.
