Plauditus cestus (Provonsha & McCafferty, 1982) is widespread in eastern and central North America. We provide new data from Virginia that fill a gap in the range of distribution and new data from the Northwest Territories that extend the range of the species by over 1900 km to the northwest. The Northwest Territories specimen represents a new larval color variant, with pronounced coloration of abdominal segment 6. We emphasize the need for additional sampling of aquatic habitats in the Far North.

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.

References to Cyclops strenuus in the North American literature are reviewed. Male and female specimens of C. strenuus sensu lato from 20 sites in Alaska, Yukon, Northwest Territories, and Saskatchewan were measured and compared using several morphological parameters. Two or more phenotypes may be present among the 20 populations. The specimens examined differ sharply from Cyclops canadensis Einsle, 1988, especially in the length of the caudal ramus, length of the antennules, width of prosomites 4 and 5, and length of the lateralmost and medialmost terminal caudal setae. Thus, Einsle's conclusion that previous records of C. strenuus in North America are likely referable to C. canadensis may be premature. New records of C. strenuus away from northern coastal areas of Alaska and Canada include Saint Matthew and Nunivak islands, two interior Alaska locations, Galena and Chatanika, and four locations in central and southern Saskatchewan. Passive dispersal via migrating waterfowl may account for the presence of C. strenuus in Saskatchewan. To date, only a very few individuals of C. strenuus s.l. from a very large area in North America have been examined. Final decisions about relationships among Nearctic C. strenuus and their relationships to Palearctic congeners must await the examination of many more animals and investigations using biochemical or chromosomal techniques in conjunction with morphology.

AbstractThe peatlands of the northern Cordillera of North America (consisting of the mountain ranges and intermontane lowlands and plateaus of British Columbia, Alberta, the Northwest Territories, the Yukon, and Alaska) support a distinctive Odonata fauna. Forty species in six families and 12 genera are typical of northwestern peatlands and another 12 species are occasional inhabitants of these environments. Of the 40 species, eight (20%) are peatland obligates and four (10%) almost always occur in such habitats. The remaining 28 (70%) are generalists and live in a wide range of aquatic habitats; nevertheless, they often are common inhabitants of, or are even dominant in, peatland environments. The fauna is dominated by the genera Aeshna Fabricius and Somatochlora Selys, with 11 and 10 species, respectively. It is also dominated by species restricted to Boreal regions (25 species, 62.5%), six (15%) of which have Holarctic distributions. The remainder of the fauna consists of eight species (20%) ranging transcontinentally in Transition Zone forests south of the Boreal Forest, five (12.5%) restricted to the Cordillera, and two (5%) with wide distributions in North America. Notes and maps summarize our knowledge of biogeographical information and previously unpublished records are listed. Significant southerly range extensions for species such as Coenagrion interrogatum (Hagen), Aeshna septentrionalis Burmeister, A. sitchensis Hagen, A. subarctica Walker, Somatochlora septentrionalis (Hagen), and Leucorrhinia patricia Walker are reported. Ecological and natural history data are outlined for each species. There do not appear to be any clear differences between the faunas of bogs and fens; dragonflies seem to respond to the habitat's form and structure rather than to its acidity or nutrient levels. Distinctive species associations result. A better understanding of the preferences of these dragonflies for different peatland microhabitats must await detailed research on oviposition behaviour and larval ecology.

Studies of the goldenrod gall caused by Eurosta solidaginis Fitch have been made by various authors who reared insects from the galls in North America, e.g. Hughes (1934), Milne (1940) and Ping (1915). Snyder (1898) described the emergence of an adult fly from a gall in Illinois. In Canada, insects have been reared from galls collected in Manitoba and the Northwest Territories by Brodie (1892), in Quebec by Fyles (1894) and in Ontario by Harrington (1895). An opportunity has been taken recently to examine specimens reared by Dr. G. Beall from galls collected at Chatham, Ontario in 1930 and to rear insects from galls in the vicinity of London, Ontario.

Justicia Linnaeus (1753: 15) is the largest genus of Acanthaceae (Wasshausen 2002). It comprises about 600 species (Graham 1988), distributed throughout the tropics and subtropics of both hemispheres, extending into the temperate regions of North America, with one species found as far north as Quebec in Canada (Wasshausen 1992a). In Brazil, the genus is represented by 128 species (Profice et al. 2015). Among them, Justicia andersonii Wasshausen (1992b: 666) is an illegitimate name, as it is a later homonym of J. andersonii Ramamoorthy (1976: 551). Therefore a new name, J. wasshausenii, is proposed as a replacement name for J. andersonii.

Insight Into

Background Anosteira pulchra is one of two species of the obligately-aquatic freshwater clade Carettochelyidae (pig-nosed turtles) from the Eocene of North America. Anosteira pulchra is typically rare in collections, and their distribution is poorly documented. The Uinta Formation [Fm.] contains a diverse assemblage of turtles from the Uintan North American Land Mammal Age. Whereas turtles are abundantly preserved in the Uinta Fm., A. pulchra has been reported only from a few specimens in the Uinta C Member. Methods We describe new records of Anosteira pulchra from the Uinta Basin and analyze the distribution of 95 specimens from multiple repositories in the previously published stratigraphic framework of the middle and upper Uinta Fm. Results Here we report the first records of the species from the Uinta B interval, document it from multiple levels within the stratigraphic section and examine its uncommon appearance in only approximately 5% of localities where turtles have been systematically collected. This study details and extends the range of A. pulchra in the Uinta Fm. and demonstrates the presence of the taxon in significantly lower stratigraphic layers. These newly described fossils include previously unknown elements and associated trace fossils, with new anatomical information presented. This study provides insight into the taxonomy of Anosteira spp. in the middle Eocene, and suggests the presence of a single species, though no synonymy is defined here due to limits in Bridger material.

AbstractThe Palearctic species Amara communis (Panzer) and Bembidion femoratum Sturm were both first reported from North America in 1992. Since that time a sizeable number of additional specimens of both species have been found, which substantially expands their known range on the continent. These records are summarized herein. The possible modes of introduction of both species are discussed within the context of other introduced insects, particularly those first found in Atlantic Canada. In the case of A. communis, the many coastal localities where it occurs would seem to indicate that it was introduced in association with transatlantic marine traffic, possibly the shipment of dry ballast. In the case of B. femoratum, the mode of introduction is less clear. Possible associations with nursery stock, dry ballast, and the movement of aircraft are all discussed.

Abstract A description is provided for Septoria cannabis. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOST: Cannabis sativa (hemp). DISEASE: White leaf spot or leaf blight of hemp. Symptoms usually appear on basal leaves as round or ellipsoidal to polygonal, whitish or ochraceous yellow lesions with a conspicuous dark brown border. Affected leaves become curled and withered up towards the edges and fall prematurely leaving much of the lower part of the stem defoliated (15, 97, 805). GEOGRAPHICAL DISTRIBUTION: Asia, Europe and North America (CMI Map No. 477, ed. 1, 1971). New records not mapped are: Asia (Kashmir, Pakistan). TRANSMISSION: Detailed studies have not been reported but conidia are presumed to be disseminated by rain-splash and wind blown water. The fungus could also be carried over in crop residues.
