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.

The Empis (Enoplempis) mira species group is revised and includes the type species of Enoplempis and four new species (E. macdonaldi sp. nov., E. submira sp. nov., E. williamturneri sp. nov., E. winkleri sp. nov.). A lectotype is designated for Enoplempis mira Bigot. The species group is defined by the yellow body colour, directionally asymmetrical male hindlegs and geniculate hindlegs in both males and females. The group has not been found outside of western North America and is known from California, Oregon, Idaho and Washington.

AbstractThe genus Japewia Tønsb. is introduced to accommodate three species including J. subaurifera Muhr & Tønsb. sp. nov. based on material from Norway, Sweden, Finland, Scotland, Canada (British Columbia) and U.S.A. (Washington). This species is closely related to Lecidea tornoensis Nyl. but is distinguished in being sorediate and by the production of lobaric acid (accessory) and acetone-soluble pigments. It grows on bark of deciduous and coniferous trees. Lecidea carrollii Coppins & P. James and L. tornoensis Nyl. are transferred to Japewia.

Terrane Accretion

Sinemurian phosphorites in southeastern British Columbia and southwestern Alberta conform with the "West Coast type" phosphorite depositional model. The model indicates that they were deposited on or near the Early Jurassic western cratonic margin, next to a sea or trough from which cold water upwelled. This suggests that the allochthonous terrane Quesnellia lay well offshore in Sinemurian time. The sea separating Quesnellia from North America was partly floored by oceanic crust ("Eastern Terrane") and partly by a thick sequence of rifted, continental terrace wedge rocks comprising the Purcell Supergroup and overlying Paleozoic sequence. This sequence must have been depressed sufficiently that access of upwelling deep currents to the phosphorite depositional area was not impeded.

AbstractBohn, H.: Revision of the panteli-group of Phyllodromica in Spain and Morocco (Blattaria: Blattellidae: Ectobiinae). Ent. scand. 24: 49-72. Copenhagen, Denmark. April 1993. ISSN 0013-8711. The species of the panteli-group are characterized by lobiform wings in both sexes and very specialized glands on tergite 7 in the males consisting of two pairs of long tubular pouches. The five or six species are distributed in southern Spain (P. panteli (Bolívar), P. coniformis sp. n., P. ignabolivari sp. n.) and northern Morocco (P. Janeri (Bolívar), P. vignai (Failla & Messina), P. sp. B). The distribution pattern suggests a colonization of Morocco from Spain across the Strait of Gibraltar. The characteristics of the panteli-group are reported, the relationship with other groups is discussed, all species are described and depicted, and keys for the identification of males and females are presented.

The millipede genus Amplaria Chamberlin, 1941 (senior synonym of Vaferaria Causey, 1958 and Speostriaria Causey, 1960) is endemic to western North America, from Mt. Palomar and San Luis Obispo, California, north to southwestern British Columbia, Canada, and east to northern Idaho. Seven species names are currently assigned to the genus. Below I describe ten additional new species: Amplaria crawfordi, Amplaria fontinalis, Amplaria rykkenae, Amplaria arcata, Amplaria baughi, Amplaria staceyi, Amplaria umatilla, Amplaria cervus, Amplaria mendocino and Amplaria flucticulus, and provide new records of Amplaria nazinta Chamberlin.

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.

AbstractWe describe timing and location of the prebasic molt in Western Tanagers (Piranga ludoviciana), focusing on age class differences in premolt movements. Most adults migrate south to the American Southwest where they stop to molt before moving on to their wintering grounds. Molting adults are found in southern mountain regions (Sierra Madres and southern Rockies) and in the Mexican monsoon region, where late summer rains cause a substantial increase in productivity. In contrast, juvenile Western Tanagers move to nearby montane habitats to molt before migrating, a previously undocumented strategy in western passerines that show molt-related movements. By molting in nearby montane habitats, juveniles avoid the aerodynamic cost of migrating in their “fluffy”, aerodynamically inefficient juvenal plumage. Western Tanagers are the fifth species known to use the Mexican monsoon region during the prebasic molt, further affirming the importance of that area to the conservation of Neotropical migrants that breed in western North America.

Phagodrilus gen.nov. (Lumbriculidae): systematics and biology of a predaceous oligochaete from western North America

The Relationship

The genus Phagodrilus (Lumbriculidae) is erected for Phagodrilus macnabi sp.nov., a predaceous worm with a paryngeo-esophageal region resembling that of Agriodrilus, a monotypic genus from Lake Baikal, often cited as a potential progenitor of the leeches. The pharynx or gizzard of Phagodrilus has the opposite dorsoventral orientation of its triangular section to that of Agriodrilus (apex dorsad in Phagodrilus, ventrad in Agriodrilus). While the latter appears closely related to Lamprodrilus in terms of its reproductive system, Phagodrilus resembles the Stylodrilus–Hrabea complex. These characteristics clearly indicate separate origins of the predatory habit and convergence of these two taxa, which suggests reexamination of the relationship between them and the leeches and branchiobdellids.
