Four new species of the lumbriculid genus Eremidrilus Fend & Rodriguez, 2003 are described from Idaho, Montana, and New Mexico. The new species all have a filiform proboscis, club-shaped atria in X, each with two functional vasa deferentia, and spermathecae paired in both XI and XII. Male pores of Eremidrilus artzaini n. sp., E. humboldti n. sp., and E. gilita n. sp. are all associated with distinctive porophores, but these structures are absent in E. montanensis n. sp. The new species are easily distinguished from California Eremidrilus species, all of which have spermathecae only in XI. New observations of type specimens of Eremidrilus allegheniensis (Cook, 1971), a species with two spermathecal segments, known only from eastern USA, confirm differences in atrial morphology, and also document unusual spermathecal porophores and ventral glands.

Kochaspids are an informal group of ptychopariid trilobites that were both abundant and widespread in the early Middle Cambrian of North America. Based on the reassociation of pygidia and cranidia of some kochaspids, Kochiella Poulsen, 1927, is redefined and Hadrocephalites n. gen. is proposed. Hadrocephalites includes taxa previously assigned by Rasetti and Palmer to Schistometopus Resser, 1938a. Schistometopus is considered nomen dubium. Representatives of Kochiella and Hadrocephalites from the Pioche Shale and Carrara Formation of Nevada are described, including the new species Kochiella rasettii, K. brevaspis, Hadrocephalites lyndonensis, and H. rhytidodes. Other kochaspids previously assigned to Kochaspis Resser, 1935; Eiffelaspis Chang, 1963; Schistometopus; and Kochiella are discussed and some are reassigned. The type specimens of Kochiella augusta (Walcott, 1886); K. crito (Walcott, 1917b); K. chares (Walcott, 1917a); K. mansfieldi Resser, 1939; K. arenosa Resser, 1939; Hadrocephalites carina (Walcott, 1917b), and H. cecinna (Walcott, 1917b) are re-illustrated.

Mite Genus

Four new species of the oribatid mite genus Carabodes from western North America are described, based on adult specimens: Carabodes california known from California, C. colorado from British Columbia, Alberta, Idaho, Wyoming, Colorado, Arizona, and New Mexico, C. dickinsoni from British Columbia, Washington, Oregon, and California, and C. hoh from British Columbia, Washington, Oregon, and California. We provide an expanded diagnosis of the genus, including information on integumental birefringence, chaetotaxy, palptarsal setation, and position of lyrifissure iad. We present a table of character states and a diagnostic key for the 28 species, as well as a summary of their distributions.

A New Species

The oribatid mite genus Protoribates Berlese (Haplozetidae) is reviewed for North America and the genus diagnosis is revised to account for the North American species, Protoribates robustior (Jacot, 1937) is redescribed and newly reported from western North America and a new species from Alberta is described. Protoribates haughlandae sp. n. is bisexual, heterotridactylous, and lives primarily in the peat soils of fens and bogs. Protoribates robustior is all-female, monodactylous, and occurs primarily in dry forests or in dry, treeless sites dominated by grasses, sedges, and shrubs. Both species feed on fungal hyphae and spores, but P. haughlandae also is an opportunistic predator and/or necrophage of small arthropods and P. robustior gut contents often include material that resembles plant cell walls. Examination of type specimens confirms that Protoribates prionotus (Woolley, 1968) is a junior synonym of the widespread Protoribates lophotrichus (Berlese, 1904). A key to differentiate Lagenobates from Protoribates and to identify the 7 species of the latter that are known or reported from North America is provided.

A New Species

Allosaurus is one of the best known theropod dinosaurs from the Jurassic and a crucial taxon in phylogenetic analyses. On the basis of an in-depth, firsthand study of the bulk of Allosaurus specimens housed in North American institutions, we describe here a new theropod dinosaur from the Upper Jurassic Morrison Formation of Western North America, Allosaurus jimmadseni sp. nov., based upon a remarkably complete articulated skeleton and skull and a second specimen with an articulated skull and associated skeleton. The present study also assigns several other specimens to this new species, Allosaurus jimmadseni, which is characterized by a number of autapomorphies present on the dermal skull roof and additional characters present in the postcrania. In particular, whereas the ventral margin of the jugal of Allosaurus fragilis has pronounced sigmoidal convexity, the ventral margin is virtually straight in Allosaurus jimmadseni. The paired nasals of Allosaurus jimmadseni possess bilateral, blade-like crests along the lateral margin, forming a pronounced nasolacrimal crest that is absent in Allosaurus fragilis.

The new species, Stenozonium leonardi, the northernmost representative of the Polyzoniidae in western North America and the only one north of the Columbia River, is described from the Olympic Peninsula of Washington; it is isolated by some 180 mi (288 km) from S. benedictae Shelley, 1998, in coastal Oregon. Stenozonium alone among the four polyzoniidan genera in western North America consists of entirely allopatric and widely separated species, with one apiece in California, Oregon, and Washington-evidence that it diversified earlier than its ordinal counterparts.
