Abstract: Epigaeic beetle assemblages were surveyed using continuous pitfall trapping during the summers of 1992 and 1993 in six widely geographically distributed locations in Alberta’s aspen-mixedwood forests prior to initial forest harvest. Species composition and turnover (β-diversity) were evaluated on several spatial scales ranging from Natural Regions (distance between samples 120–420 km) to pitfall traps (40–60 m). A total of 19,885 ground beetles (Carabidae) representing 40 species and 12,669 rove beetles (non-Aleocharinae Staphylinidae) representing 78 species was collected. Beetle catch, species richness, and diversity differed significantly among the six locations, as did the identity of dominant species. Beetle species composition differed significantly between the Boreal Forest and Foothills Natural Regions for both taxa. Staphylinidae β-diversity differed significantly between Natural Regions, whereas Carabidae β-diversity differed among locations. Climate variables such as number of frost-free days, dry periods, and mean summer temperatures were identified as significant factors influencing beetle assemblages at coarse spatial scales, whereas over- and understory vegetation cover, litter depth, shade, slope, and stand age influenced beetle assemblages at finer spatial scales. Significant interannual variation in assemblage structure was noted for both taxa. Because composition of epigaeic beetle assemblages differed across spatial scales, forest management strategies based only on generalized understanding of a single location will be ineffective as conservation measures. In addition, site history and geographic variation significantly affect species distributions of these two beetle families across the landscape. Thus, we underscore Terry Erwin’s suggestion that biodiversity assessments focused on species assemblages at different spatial scales provide a sound approach for understanding biodiversity change and enhancing conservation of arthropod biodiversity.

A new species of rake-legged mite, Caeculus cassiopeiae (Prostigmata, Caeculidae), from Canada and a systematic analysis of its genus https://zookeys.pensoft.net/article/48741/ ZooKeys 926: 1-23

DOI: 10.3897/zookeys.926.48741

Authors: Jared Bernard, Lisa M. Lumley, Matthias Buck, Tyler P. Cobb

Abstract: The genus Caeculus Dufour (Prostigmata, Caeculidae) contains 19 previously described species, most of which are found in North America, and for which no comprehensive phylogenetic treatment exists. Here, one new species from Alberta, Canada, is described: Caeculus cassiopeiae Bernard & Lumley, sp. nov., and another caeculid known to be present in Canada is documented. The new species is characterized within the genus with a character state matrix, from which an updated key is produced. A systematic analysis of all 20 species based on morphological and geographical distribution traits obtained from literature represents the first phylogenetic review of the genus.

Grylloblattodea of Canada https://zookeys.pensoft.net/article/24289/ ZooKeys 819: 271-276

DOI: 10.3897/zookeys.819.24289

Authors: Sean D. Schoville

Abstract: The enigmatic insect order Grylloblattodea comprises two described species in Canada, which are limited to the Montane Cordillera and Pacific Maritime ecozones. One of the described species has three Canadian subspecies of uncertain taxonomic ranking, and there are two additional undescribed or unreported species known in close proximity to the Canadian border in western Alberta and British Columbia that likely also occur in Canada. Thus, as much as 50% of the total taxonomic diversity of Grylloblattodea in Canada is still undocumented. Targeted surveys and taxonomic work, as well as studies that describe the ecology and conservation status of Grylloblattodea are important goals for future research.

Diplura and Protura of Canada https://zookeys.pensoft.net/article/25238/ ZooKeys 819: 197-203

DOI: 10.3897/zookeys.819.25238

Authors: Derek S. Sikes

Abstract: A literature review of the Diplura and Protura of Canada is presented. Canada has six Diplura species documented and an estimated minimum 10–12 remaining to be documented. The Protura fauna is equally poorly known, with nine documented species and a conservatively estimated ten undocumented. Only six and three Barcode Index Numbers are available for Canadian specimens of Diplura and Protura, respectively.

Addition of a new Quedius Steph. (Coleoptera, Staphylinidae) species to the biodiversity of Albertan mixedwood forest, Canada https://zookeys.pensoft.net/article/12320/ ZooKeys 668: 61-68

DOI: 10.3897/zookeys.668.12320

Authors: Jenna M. Jacobs, J. A. Colin Bergeron

Abstract: Quedius (Raphirus) spencei Jacobs and Bergeron, new species, (Coleoptera: Staphylinidae), is described based on specimens from two localities (type locality: 35 km. E Dixonville, Alberta, Canada) in the Boreal Forest. Male genitalia are illustrated, compared with congeners (Q. rusticus Smetana and Q. simulator Smetana) in the Aenescens species group, and included in a slightly modified key to the species of Quedius.

Landscape patterns of species-level association between ground-beetles and overstory trees in boreal forests of western Canada (Coleoptera, Carabidae) https://zookeys.pensoft.net/article/2935/ ZooKeys 147: 577-600

DOI: 10.3897/zookeys.147.2098

Authors: Colin Bergeron, John Spence, Jan Volney

Abstract: Spatial associations between species of trees and ground-beetles (Coleoptera: Carabidae) involve many indirect ecological processes, likely reflecting the function of numerous forest ecosystem components. Describing and quantifying these associations at the landscape scale is basic to the development of a surrogate-based framework for biodiversity monitoring and conservation. In this study, we used a systematic sampling grid covering 84 km2 of boreal mixedwood forest to characterize the ground-beetle assemblage associated with each tree species occurring on this landscape. Projecting the distribution of relative basal area of each tree species on the beetle ordination diagram suggests that the carabid community is structured by the same environmental factors that affects the distribution of trees, or perhaps even by trees per se. Interestingly beetle species are associated with tree species of the same rank order of abundance on this landscape, suggesting that conservation of less abundant trees will concomitantly foster conservation of less abundant beetle species. Landscape patterns of association described here are based on characteristics that can be directly linked to provincial forest inventories, providing a basis that is already available for use of tree species as biodiversity surrogates in boreal forest land management.

An annotated list of the Lepidoptera of Alberta, Canada https://zookeys.pensoft.net/article/2163/ ZooKeys 38: 1-549

DOI: 10.3897/zookeys.38.383

Authors: Greg Pohl, Gary Anweiler, Christian Schmidt, Norbert Kondla

Abstract: This checklist documents the 2367 Lepidoptera species reported to occur in the province of Alberta, Canada, based on examination of the major public insect collections in Alberta and the Canadian National Collection of Insects, Arachnids and Nematodes. Records from relevant literature sources published since 1950 and from selected older works are also included. The entry for each species includes the scientific name, the author and year of publication of the original description, occurrence status, provincial distribution (according to ecoclimatic region), and adult phenology. The most recent taxonomic references are given, and common names are listed for butterflies and conspicuous moth species. The sources of specimen- and literature-based records are provided for each species. An additional 138 species whose occurrence in Alberta is probable are appended to the list. For 1524 of the listed species and subspecies, annotations are given, with selected information on taxonomy, nomenclature, distribution, habitat, and biology. An additional section provides details on 171 species erroneously reported from Alberta in previous works. Introductory sections to the volume provide a general overview of the order Lepidoptera and review the natural regions of Alberta, the state of knowledge of their Lepidoptera faunas, and the history and current state of knowledge of Alberta Lepidoptera. Each of the 63 families (and selected subfamilies) occurring in Alberta is briefly reviewed, with information on distinguishing features, general appearance, and general biology. A bibliography and an index of genus-level, species-level, and subspecies-level names are provided. The list is accompanied by an appendix of proposed nomenclature changes, consisting of revised status for 25 taxa raised from synonymy to species level, and new synonymy for 20 species-level and one genus-level taxa here considered to be subjective synonyms, with resultant revised synonymy for one taxon and formalization of seven new combinations. Status is revised for the following taxa, which were previously treated as junior subjective synonyms or as subspecies and are herein raised to species status: Carterocephalus mandan (Edwards, 1863); Hesperia manitoba (Scudder, 1874); Colias elis Strecker, 1885; Nymphalis j-album (Boisduval & LeConte, [1835]); Euphydryas bernadetta Leussler, 1920; Speyeria leto (Behr, 1862); Boloria myrina (Cramer, 1777); Coenonympha inornata Edwards, 1861; Colostygia circumvallaria (Taylor, 1906); Xanthorhoe delectaria Cassino & Swett, 1922; Xanthorhoe lagganata Swett & Cassino, 1920; Scopula quinquelinearia (Packard, 1870); Spodolepis danbyi (Hulst, 1898); Hyalophora gloveri (Strecker, 1872); Smerinthus ophthalmica Boisduval, 1855; Furcula borealis (Guerin-Meneville, 1844); Furcula occidentalis (Lintner, 1878); Acronicta cyanescens Hampson, 1909; Oligia rampartensis Barnes & Benjamin, 1923; Anarta nigrolunata Packard, 1867; Anarta columbica (McDunnough, 1930); Anarta montanica (McDunnough, 1930); Leucania dia (Grote, 1879); Euxoa adumbrata thanatologia (Dyar, 1904); and Euxoa furtivus (Smith, 1890). The following new synonymies are proposed, with the valid name presented first: Xanthorhoe algidata (Moschler, 1874) (= Xanthorhoe dodata Cassino & Swett, 1920), Macaria signaria (Hubner, 1809) (= Melanolophia unipunctaria W. S. Wright, 1916; Semiothisa marmorata Ferguson, 1972; Macaria? submarmorata Walker, 1861), Speranza occiduaria (Packard, 1874) (= Diastictis andersoni Swett, 1916), Caenurgina crassiuscula (Haworth, 1809) (= Caenurgina distincta (Neumoegen, 1884)), Tarache augustipennis Grote, 1875 (= Conacontia flavicosta Smith, 1900), Acronicta dactylina Grote, 1874 (= Acronicta hesperida Smith, 1897), Acronicta grisea Walker, 1856 (= Acronicta tartarea Smith, 1903), Acronicta lupini Grote, 1873 (= Merolonche ursina Smith, 1898), Fishia yosemitae (Grote, 1873) (= Fishia enthea Grote, 1877; Fishia betsia Smith, 1905; Fishia instruta Smith, 1910), Sutyna privata (Walker, 1857) (= Anytus profundus Smith, 1900), Mniotype ducta (Grote, 1878) (= Xylophasia versuta Smith, 1895), Mniotype tenera (Smith, 1900) (= Xylophasia miniota Smith, 1908; Hadena ferida Smith, 1908), Anarta decepta (Grote, 1883) (= Trichoclea postica Smith, 1891), Protorthodes incincta (Morrison, 1874) (= Taeniocampa utahensis Smith, 1888; Orthodes akalus Strecker, 1898). The following revised synonomy is proposed, with the valid name presented first: Xanthorhoe lagganata Swett & Cassino, 1920 (= Xanthorhoe incursata var. harveyata Cassino & Swett, 1922). One new generic synonymy is proposed, with the valid name appearing first: Idia Hubner, 1813 (= Reabotis Smith, 1903), resulting in one new combination. Six species are transferred from Trichoclea Hubner to Sideridis Hubner, resulting in six new combinations.
