AbstractThe genus Stomis Clairville is redefined. It includes two subgenera: Neostomis subg. nov. (type-species: Pterostichus termitiformis Van Dyke) with one Nearctic species and Stomis s. str. with 15 Palaearctic species. Eustomis Semenov, previously considered as a distinct genus, is synonymized with Stomis s. str. Description of the genus Stomis and of the two subgenera, as well as a diagnosis and comments on ranking and relationships of the genus, are provided.

Two new genera of Chamaemyiidae (Diptera: Lauxanioidea) are described and illustrated, including: Chamaethrix gen. nov. (type species Chamaethrix necopina sp. nov.), possibly a predator of Cinara ponderosae (Williams) on Pinus ponderosa in the southwestern United States; and Vitaleucopis gen. nov. (type species Vitaleucopis nidolkah sp. nov.; other included species Vitaleucopis astonea (McAlpine), comb. nov., and Vitaleucopis scopulus sp. nov.), predators of Cinara aphids and possibly adelgids on Pinaceae in western North America. Immature stages are discussed or described and illustrated for some taxa, including the eggs of Chamaethrix necopina and Vitaleucopis nidolkah; and the third instars and puparia of Vitaleucopis nidolkah.

The Relationship

Baeomyia n.g. is described for a group of small (2–3 mm long) tachinids belonging to the Siphona group of the Siphonini. All known specimens were collected in western North America, with two species recorded from southern British Columbia (Baeomyia xanthogaster n. sp. and Baeomyia juniperi n. sp.) and three species recorded from desert localities in the American Southwest (type-species Baeomyia hurdi (Reinhard), Baeomyia antennata n. sp. and Baeomyia sonorensis n. sp.). Keys to adult males and females are provided for separation of species. Systematics of the Siphonini and Siphona group are reviewed, including a discussion of the synapomorphies upon which each is defined. Baeomyia species are inferred to form a monophyletic taxon within the Siphona group on the basis of five synapomorphies, though the relationship between the genus and other Siphona group taxa is unresolved. The apparent disjunction of Baeomyia species into northern and southern ranges may be the result of relatively recent speciation events, because differences among species are slight. A detailed zoogeographic analysis of the distribution pattern must await further phylogenetic data.

Orthographic Errors

Nomenclatural omissions and orthographic errors in my 1994 monograph are corrected. The three genera Calliderma, Clitopiloides, and Fibropilus were validly published in 1994 as stat. nov. based on infrageneric names, and their extraterritorial basionym type species are proposed here as Ca. callidermum comb. nov., Cl. cyathus comb. nov., and F. fumosifolius comb. nov. Names originally proposed as provisional are validated as Leptonia cyanea comb. nov., L. cyanea var. occidentalis var. nov., and Inocephalus appressus sp. nov. Nolanea names that were illegitimate later homonyms are proposed as N. undatomarginata comb. nov. and N. papillatoides comb. nov., based on published replacement names. The published validation of the invalid 1994 name "Leptonia violacea" is indicated, and seven orthographic epithet corrections are listed

Generic Distribution

The family Macrosternodesmidae is redefined and recorded from western North America. Four small-bodied species in Arizona and California, USA, and Baja California Norté, Mexico, are assigned to Tidesmus Chamberlin 1943; Phreatodesmus and Oodedesmus, both authored by Loomis, 1960, are placed in synonymy. Phreatodesmus torreyanus Loomis, 1960 and O. variabilis Loomis, 1960, are transferred into Tidesmus as valid species; P. cooki Loomis, 1960, is a synonym of T. episcopus Chamberlin, 1943, the type species, and P. dentatus Loomis, 1960, is a synonym of P. torreyanus. Brachydesmus hastingsus Chamberlin, 1941, also is referable to Tidesmus; a topotypical male is needed to establish its identity in the absence of authentic type specimens. Tidesmus hubbsi Chamberlin, 1943, based on unidentifiable females, is geographically segregated and incompatible with the otherwise coherent generic distribution. A topotypical male is also necessary to determine its identity; for now, we remove hubbsi from Tidesmus and leave it unassigned.

The wolf spider genus Alopecosa Simon, 1885, contains 160 named species (Platnick 2012) and the type species of the genus is A. fabrilis (Clerck, 1757), which is a Palaearctic species like most species in the genus (Platnick 2012). The taxonomic structure of the genus has been studied in two revisions; Lugetti & Tongiorgi (1969) divided 24 species of European Alopecosa into five species groups and Dondale & Redner (1979) divided seven species from North America into three groups. Many species currently in Alopecosa do not appear to be related to the type species; hence the genus is polyphyletic and should be divided into several genera (Marusik & Kovblyuk 2011). Faunistic revisions of Alopecosa have been produced for Italy (Lugetti & Tongiorgi 1969), Romania (Fuhn & Niculescu-Burlacu 1971), North America (Dondale & Redner 1979), China (Song et al. 1999) and Sweden (Almquist 2005). In the Ukraine and European Russia, 18 and 22 species have been reported, respectively (Mikhailov 1997, 2000). Twenty species of Alopecosa have been described since the year 2000 (Platnick 2012), including one from Central Europe (Czech Republic and Slovakia) (Buchar 2001), one from Greece (Buchar 2001), one from Southwestern Russia and six species from Western Kazakhstan (Ponomarev 2007, 2008, 2009).

A New Species

AbstractCambrian strata of the Laurentian craton contain numerous examples of Burgess Shale–type faunas. Although displaying a more or less concentric distribution around the cratonal margin, most faunal occurrences are in present-day western North America, extending from the Northwest Territories to California. Nevertheless, the soft-bodied and lightly skeletalized fossils in most of these Lagerstätten are highly sporadic. Here, we extend knowledge of such Middle Cambrian occurrences in Utah with reports of four taxa. An arthropod from the Marjum Formation, Dytikosicula desmatae gen. et sp. nov., is a putative megacheiran. It is most similar to Dicranocaris guntherorum, best known from the younger Wheeler Formation, but differs primarily in the arrangement of pleurae and overall size. Along with a specimen of ?Yohoia sp, a new species of Yohoia, Y. utahana sp. nov., is described. It differs from the type and only known species, Y. tenuis, principally in its larger size and shorter exopods; it is the first description of this genus from outside the Burgess Shale. A new species of a stem-group lophotrochozoan from the Spence Shale, Wiwaxia herka sp. nov., possesses a palisade of dorso-lateral spines that are more robust and numerous than the type species of Wiwaxia, W. corrugata. Another notable taxon is Eldonia ludwigi from the Marjum Formation, which is interpreted as a primitive ambulacrarian (assigned to the cambroernids) and a new specimen of the ?cnidarian Cambrorhytium from the Wheeler Shale is illustrated.

AbstractThe oribatid mite genus Ametroproctus, soil and litter inhabitants in the desert, alpine, and montane regions of western North America, is discussed. Two subgenera are recognized, Ametroproctus s. str. and Coropoculia. Their respective type-species, A. oresbios Higgins and Woolley and C. reticulata Aoki and Fujikawa, are redescribed, and newly discovered immatures of both species are described. Four new species are proposed, A. (Ametroproctus) tuberculosus, A. (A.) aridus, A. (Coropoculia) beringianus, and A. (C.) canningsi. A new generic diagnosis is given, as well as a key to subgenera and species known from North America.

AbstractThe tcttigoniine katydids of South America are reviewed. All species occur in Chile and adjacent Argentina. Four tettigoniine genera are recognized from South America. Calodectes gen.n. with 1 species from Chile, crybeloplatus sp. n., is unrelated to any other. Xyrdectes gen. n. contains 2 species from Chile, type-species chileno sp. n. and fuscescens (Blanchard), comb. n. Falcidectes gen. n. is from Chile with 2 species, type-species divisus sp. n. and xyelus sp. n.; however, nymphs indicate more may exist. Platydecticus Chopard with 15 species, type-species angustifrons Chopard from Argentina and Chile, gubernaculus sp. n., hubbelli sp. n., mammantus sp. n., manacus sp. n., onax sp.n., philopenus sp. n., primnocaudus sp.n., sagariferus sp.n., pheroxiphus sp. n., robertsi sp. n., rupicolus sp. n., simplex sp. n., tumidiplatus sp. n., and darwini sp. n. all from Chile. The relationships of the genera are found to be with Australia and western North America (genus Neduba Walker). None of the genera shows links with Africa. A similar-looking genus and species from Chile, Coniungoptera gen. n. (type-species nothofagi sp.n.) associated with Nothofagus, is nearest related to Metholce Walker and Veria Walker of Australia, and a new tribe, Coniungopterini is proposed for these three genera of Conocephalinae.

Baiotomeus is a new genus of ptilodontid multituberculate from the late Torrejonian Land-Mammal Age (late middle Paleocene) of western North America. Baiotomeus douglassi (Simpson), the type species, has been assigned, at one time or another, to Ptilodus, Mimetodon, and Neoplagiaulax. In addition, a second, new species, B. lamberti, from three localities in the Medicine Rocks area of southeastern Montana is reported here. The Medicine Rocks localities are tentatively assigned a latest Torrejonian age, younger than localities yielding B. douglassi and younger than previously suggested on the basis of plesiadapid primates.Multituberculates appear to have attained their highest species richness during the Torrejonian Land-Mammal Age, but the discovery of B. lamberti illustrates that our knowledge of multituberculate diversity is incomplete from even that interval of time.
