Two New Species

AbstractLarvae, deutonymphs, and male and female adults of Platyhydracarus juliani sp.nov., and adults of P. parvipalpis sp.nov., are described from rheocrenes and small streams in western North America. The genus Platyhydracarus gen.nov. is proposed and diagnosed, based primarily upon the presence of genital acetabula both in the gonopore and on acetabular plates flanking the gonopore, and of a group of thickened setae anterior to the gonopore, in male adults. Possible relationships between Platyhydracarus and other Athienemanniidae are discussed, and a new key to the genera of Athienemanniinae is presented.

AbstractDeutonymphs, and male and female adults, of Stygameracarus cooki sp.nov., and a male adult of S. canadensis sp.nov., are described from interstitial habitats associated with small streams in temperate North America. The genus Stygameracarus and the monobasic subfamily Stygameracarinae are proposed and diagnosed, based primarily on the shape of the capitulum and the highly modified structure of the pedipalps in both deutonymphs and adults, and the distinctive structure of the genital field region in adults. Possible relationships between members of the new genus and other Athienemanniidae are discussed, and a new key to the subfamilies of Athienemanniidae is presented.

A New Species

The genus Admetovis Grote is revised. Admetovisicarussp. n. is described from the mountains of western North America. A lectotype of Admetovisoxymorus Grote is designated. Illustrations of the adults, male and female genitalia, and distribution maps are presented, together with an identification key. The classification of the genus is reviewed resulting in its reassignment to the tribe Hadenini from Orthosiini.

AbstractLarvae, and male and female adults, of Acalyptonotus neoviolaceus n. sp., and male and female adults of A. pacificus n. sp., are described from western North America. A revised diagnosis of Acalyptonotus is proposed based upon larvae and adults, and the phylogenetic relationships and taxonomic status of Acalyptonotidae are discussed.

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.

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.
