Biogeographic Analysis

AbstractThe genus Eudasyphora Townsend 1911 is resurrected from junior synonymy and recognized with the genera Dasyphora Robineau-Desvoidy 1830 and Pyrellia Robineau-Desvoidy 1830. Rypellia Malloch 1932 is a subgenus of Eudasyphora, but Dasypyrellia Lobanov 1976 is reported as synonym novum. A key to the species of Eudasyphora is presented. Two new species are described: E. cordilleriana n. sp. from western North America, and E. canadiana n. sp. from northern North America. The phylogenetic and biogeographic analysis led to the following conclusions: Eudasyphora became separated from its sister genus Pyrellia before the beginning of the Pleistocene glaciations. The Rypellia line evolved further in the Oriental Region, whereas the Eudasyphora s. str. line developed in the Holarctic Region. Speciation in both subgenera is correlated with the history of the forest vegetation during the Pleistocene.

AbstractEight species of Epidamaeus of arctic western North America and extreme northeast, U.S.S.R. are discussed. Two new species, Epidamaeus hammerae and E. tritylos, are proposed and E. arcticolus, E. kodiakensis, E. mackenziensis, E. bakeri, E. coxalis and E. fortispinosus, previously described by Hammer, are redescribed.

Insight Into

Two new species of the subterranean amphipod genus Stygobromus are described from groundwater habitats in Siberia: Stygobromus mikhaili n. sp. from a spring in the Central Altay Mountains and Stygobromus anastasiae n. sp. from two non-freezing springs in South Pribaikalye in the Irkutsk area. Additional taxonomic details of the previously described S. pusillus (Martynov) from Teletskoye Lake, also in Central Altay, are illustrated based on syntype material. Utilization of SEM has revealed a tiny structure on antenna 2 that appears to be a new character, and may prove useful in future analyses. Descriptions of the two new species raise the total number of described species in the genus Stygobromus to 134, but four or possibly five have been found in the Palearctic region outside North America. However, it is likely that continued exploration of subterranean groundwater habitats in Siberia and other parts of the Palearctic will reveal additional new species of Stygobromus and provide more insight into the origin and geographic distribution of this large, northern hemisphere, subterranean freshwater amphipod genus. Careful evaluation of taxonomic affinities of the new species and comparison with previously described congeners should provide further insight into the biogeographic history of Stygobromus.

Middle Member

Two new species of worm tubes referable to the genus Onuphionella occur in Lower Cambrian strata in eastern California and western Nevada. Onuphionella durhami n. sp. is found in the Campito Formation (in pre-trilobite strata, in the Fallotaspis and, possibly, the Nevadella Zones) and O. claytonensis n. sp. occurs in the Middle Member of the Poleta Formation (Nevadella Zone). The unusual tubes are armored with an imbricated coat of mica flakes, reminiscent of the modern genus Owenia. The lowest occurrence of Onuphionella in western North America corresponds closely with the lowest occurrence of the genus in the Baltic region, indicating that correlations between the two regions are not greatly in error.

Alastria chicosp. nov. is described from western North America and Alastria machosp. nov. is described from Costa Rica. We provide illustrations of the adults and genitalia of all three species, as well as the male genitalia of two related genera, Nedra Clarke and Actinotia Hübner.

The subgenus Marquesania Womersley (Acari : Atopomelidae : Listrophoroides) is revised. The species of this subgenus are permanent parasites living in the fur of rats (Rodentia : Murinae) in the Oriental region, Australia and New Guinea. Most of the type material has been examined. Two new species, Listrophoroides melomys, sp. nov. from Melomys moncktoni (Thomas) and L. mordax, sp. nov. from Rattus mordax (Thomas) are described from New Guinea. A new diagnosis of the subgenus Marquesania, detailed descriptions, and a key for all species is provided. The phylogenetic reconstruction of the subgenus Marquesania was effected by the method of parsimonius cladistics. The monophyly of the subgenus is strongly supported by this analysis, and most species from the Oriental region fall at the base of the cladogram. The distribution of Marquesania species on their hosts is discussed. It is suggested that these mites originated in the Oriental region and then migrated to Australia and New Guinea. The distribution of Marquesania species in the Australian and New Guinean regions is noticeably complicated, reflecting the complex settling history of their hosts.

AbstractSpecies of Braggia Gillette and Palmer (Hemiptera: Aphididae: Aphidinae: Aphidini) feed on various buckwheat, Eriogonum Michx. (Polygonaceae), species in western North America. Two new species, Braggia columbiana Pike n. sp. from Washington and Oregon and Braggia longicauda Pike n. sp. from Washington, Oregon, and northern California, are proposed. Descriptions, diagnoses, illustrations, mitochondrial cytochrome c oxidase subunit 1 “barcode” sequences, a key to the species of Braggia, and notes on biology, distribution, and parasitoid associations are provided.
