AbstractEight species of the siphonine genus Actia Robineau-Desvoidy are recognized in the Nearctic Region, including four that are new: A. dasymyia sp.nov. (type-locality 21 mi. east Tuktoyaktuk, North West Territories, Canada), A. dimorpha sp.nov. (type-locality Sapelo Island, Georgia, USA), A. radialis sp.nov. (type-locality Gatineau Park, Quebec, Canada), and A. sternalis sp.nov. (type-locality mi. 51 Dempster Highway, Yukon, Canada). Adults of the eight species are keyed, described, illustrated (heads, wings, and male terminalia), and their distributions mapped. The species are arranged into three species groups: the autumnalis-group with Nearctic members A. autumnalis (Townsend), A. rufescens (Greene), A. diffidens Curran, and A. dimorpha sp.nov.; the lamia-group with Nearctic members A. interrupta Curran, A. dasymyia sp.nov., and A. radialis sp.nov.; and the crassicornis-group with the single Nearctic member A. sternalis sp.nov. Nearctic Actia are inferred to be of relatively recent origin because only the A. autumnalis/A. rufescens species pair seems to have speciated within the Nearctic Region. Actia autumnalis/A. rufescens, A. diffidens, and A. dimorpha are each hypothesized to have their closest phylogenetic affinities with Neotropical species, and A. sternalis, A. interrupta, A. dasymyia, and questionably A. radialis are each hypothesized to have their closest affinities with Palearctic species.

AbstractNine species of Ceromya Robineau-Desvoidy (Diptera: Tachinidae: Siphonini) are recognized in the Nearctic region, including four new species, and one described species known previously only from the Palearctic region. The species are arranged into three species groups, with each group hypothesized to be monophyletic and each containing extralimital members. The three species groups and nine Nearctic species are as follows: the bicolor-group with C. bicolor (Meigen) (a Holarctic species newly recorded from the Nearctic region); the flaviseta-group with C. Ontario (Curran) and C. palloris (Coquillett); and the americana-group with C. americana (Townsend), C. balli sp.nov. (type-locality Masham Township, Quebec, Canada), C. elyii (Walton), C. flava sp.nov. (type-locality Masham Township, Quebec, Canada), C. oriens sp.nov. (type-locality Masham Township, Quebec, Canada), and C. occidentalis sp.nov. (type-locality Lakelse Lake, British Columbia, Canada). The bicolor-group has an Old World – Nearctic distribution, the flaviseta-group has an European–Nearctic distribution, and the americana-group has a Neotropical–Nearctic distribution. Adults of the nine Nearctic species of Ceromya are keyed and described, known hosts are listed (including corrections to published records), distributions are mapped, and taxonomically useful features are illustrated.

AbstractThis revision recognizes 13 species of Stilpon Loew in the Nearctic Region, including nine new species. A key is provided for the identification of adult specimens, all species are described, and their geographical distributions are mapped. Two informal species groups are recognized in the Nearctic Region, with the following included species: (1) S. graminum group — S. campestris Cumming sp.nov. (type-locality Assiniboia, Saskatchewan, Canada); (2) S. varipes group — S. chillcotti Cumming sp.nov. (type-locality 10 km E Evergreen, Alabama, USA), S. ctenistes Cumming sp.nov. (type-locality Salmon Creek, New York, USA), S. curvipes Melander, S. limitaris Cumming sp.nov. (type-locality Sapelo Island,Georgia,USA), S. pauciseta Melander, S. pilomus Cumming sp.nov. (type-locality Franconia, New Hampshire, USA), S. spinipes Melander, S. tribulosus Cumming sp.nov. (type-locality Gatlinburg, Tennessee, USA), S. tyconyx Cumming sp.nov. (type-locality Bedford, Massachusetts, USA), S. varipes Loew, S. vockerothi Cumming sp.nov. (type-locality Ottawa, Ontario, Canada), and S. wirthi Cumming sp.nov. (type-locality Dennisport, Massachusetts, USA). A world list of described species of Stilpon, including synonyms, is provided. Stilpon pectiniger Melander is a new junior synonym of S. varipes Loew and S. demnatensis Vaillant is indicated as a nomen nudum. Stilpon pleuriticus Melander, previously considered to belong within Stilpon, is excluded from the genus, and S. obscuripes Adams is transferred as Crossopalpus obscuripes (Adams) comb.nov. Lectotypes are designated for S. pauciseta Melander and S. pectiniger Melander. Homologies of previously confused structures of the male and female terminalia are summarized with reference to other Empidoidea. The monophyly of Stilpon is justified, including discussion of the phylogenetic relationships of the genus to the remainder of the Tachydromiinae. All described species of Stilpon, including extralimital species, are assigned to one of three proposed informal species groups (S. divergens, S. graminum, or S. varipes group), and zoogeographic patterns are discussed.

AbstractThe genus Frontiniella Townsend is transferred from the Eryciini to the Goniini, based on the production of microtype eggs in adult females. Frontiniella is known only from the Nearctic Region and the northern extreme of the Neotropical Region. Eufrontina Brooks is newly synonymized with Frontiniella and all species formerly placed in that genus are transferred to Frontiniella. Frontiniella is hypothesized to be monophyletic based on two derived character states: long hairs on the male surstylus, and elongate posterior spiracles on the puparium. Two species groups are recognized, one with six species and the other with four: the parancilla-group with F. parancilla Townsend, F. incarcerata sp.nov. (type-locality Hwy. 366, Graham Co., Arizona, USA), F. spectabilis (Aldrich) (new combination), F. surstylata sp.nov. (type-locality near Olustee, Florida, USA), F. jorgenseni sp.nov. (type-locality 20 miles northwest of Kenna, New Mexico, USA), and F. ethniae (Brooks) (new combination); and the festinans-group with F. festinans (Aldrich and Webber), F. apache sp.nov. (type-locality Sulphur Draw, Chiricahua Mts., Arizona, USA), F. mitis (Curran), and F. regilla (Reinhard). This revision includes a key to the 10 known species of Frontiniella, a description of each species (including puparium where known), maps of species distributions, an annotated list of hosts (including corrections to previously published records and additions from material examined), and illustrations of taxonomically useful features.

AbstractCyzenis Robineau-Desvoidy is a member of the Goniini, a tribe characterized by the production of microtype eggs in adult females. A new concept of Cyzenis is proposed based on a synapotypic character state of adults, i.e. the presence of narrowly separated discal scutellar setae. Two monophyletic species groups are recognized, containing a total of five species in the Nearctic Region: the albicans-gcoup with C. albicans (Fallén) (a species introduced to North America from Europe), C. pullula (Townsend), and C. browni (Curran); and the incrassata-graup with C. incrassata (Smith) and C. ustulaia (Reinhard). A Palearctic species, C. jucunda (Meigen), is recognized as a member of the albicans-group. Phorocera anassa Reinhard is newly synonymized with C. incrassata. Phorocera festbums Aldrich and Webber, Phorocera mitis Curran. and Phorocera regilla Reinhard are transferred from Cyzenis to Eufrontina Brooks (new combinations). A lectotype is designated for C. albicans (Fallén). Nearctic species of Cyzenis are keyed and redescribed, their distributions are mapped, and external, terminate, and puparial features are illustrated. Distinction of individuals of C. albicans and C. pullula is discussed in relation to ecological studies on die host–parasite pair of C. albicans and the winter moth, Operophtera brumata (Linnaeus) (Lepidoptera: Geometridae).

AbstractThere are 16 species of Trichoclinocera Collin recognized from the Nearctic region, including eight new species. Four of six species-groups of Trichoclinocera are recognized in the Nearctic region, with the following included species: (1) T. comata group — T. cascadensis sp.nov. (type-locality Starvation Creek, Oregon, U.S.A.), T. comata (Melander) comb.nov., and T. rupestris sp.nov. (type-locality Newton Creek, Wyoming, U.S.A.); (2) T. dolicheretma group — T. dolicheretma (Melander); (3) T. lapponica group — T. lapponica (Ringdahl) comb.nov.; (4) T. longipes group — T. agilis sp.nov. (type-locality Fall Creek Falls, Tennessee, U.S.A.), T. ctenistes (Melander), T. dasycoxa sp.nov. (type-locality Ottawa, Ontario, Canada), T. falcata sp.nov. (type-locality Gatineau Park, Quebec, Canada), T. fumosa (Vaillant) comb.nov., T. hamifera (Melander), T. longipes (Walker). T. minor (Melander), T. ozarkensis sp.nov. (type-locality Haw Creek Falls, Arkansas, U.S.A.), and T. pectinifemur sp.nov. (type-locality Phoenixville, Pennsylvania, U.S.A.). The following new synonyms are proposed: T. brunnipennis (Melander) = T. dolicheretma; and Seguyella saltans (Vaillant) = T. hamifera. Lectotypes are designated for T. comata, T. ctenistes, T. dolicheretma, T. brunnipennis, T. hamifera, T. lapponica, and T. stackelbergi Collin. Seguyella Vaillant and Acanthoclinocera Saigusa are newly synonymized with Trichoclinocera and all species formerly placed in these genera are transferred to Trichoclinocera, except Acanthoclinocera glaucescens (Brunetti) which is transferred as Wiedemannia glaucescens (Brunetti) comb.nov.This revision includes a key to Nearctic species, a description of each species, and maps of species distributions. Homologies of male terminalia of Clinocerinae are summarized and the first descriptions of the immature stages of species of Trichoclinocera also are provided. A world list of described species of Trichoclinocera is provided and all species are assigned to one of six species-groups, except T. cummingi sp.nov. (type-locality Robber’s Cave, Oklahoma. U.S.A.), T. fluviatilis (Brunetti) comb.nov., T. fuscipennis Saigusa, and T. maewa Smith, which remain unplaced. The monophyly of Trichoclinocera is justified and phylogenetic relationships to the remaining Clinocerinae and among species-groups are discussed.

Seawalls, revetments and groynes designed to protect shorelines require normally timber, natural stone or concrete for their construction. In Tuktoyaktuk, none of these materials is available and to avoid excessive costs, an alternative form of construction, using long sausage shaped tubes filled with sand, was devised on an experimental basis. Tuktoyaktuk is situated on the eastern side of Kugmallit Bay in the Western Arctic at north latitude of 69 deg. 27' and west longitude of 133 deg. 02'. It is approximately 90 miles north of Inuvik and 1450 miles northwest of Edmonton (figure 1). The area is mainly comprised of a long, narrow, boot-shaped peninsula oriented in approximately north-south direction, a complex lagoon, which has been developed as a harbour, east of the peninsula and an island straddling the mouth of the lagoon (figure 2). Certain dwellings exist at the southern and southeasterly shores of Tuktoyaktuk Harbour. A large majority of the inhabitants reside in settlements developed on the peninsula and the southern area linking the peninsula with the mainland. Tuktoyaktuk is used as a transfer point linking the Mackenzie River barge transport with coastwide shipping serving the western arctic seaboard and inland settlements and bases. As a result of this the TCJK settlement has grown to be the largest of the western arctic coast settlements.

Hygienic Conditions

There are presented the results of a 21-year-old (1991-2012) monitoring of Hg concentrations and amounts of metals, including heavy and toxic, Zc(MnCrVNiCoCuAgZnPbSnMo) in soils of the zone of the exposure to emissions from Astrakhan gas complex (AGK), working from 1987 within a radius of 50 km. On those criteria for the period over 1997-2012 there was revealed a steady deterioration of ecological-hygienic conditions of the lands in the control zone. The spatial variability of this condition is largely controlled by the dispersion of the emissions by the prevailing easterly and southeasterly winds. The content of Hg in 2007, remote from AGK by 15 km, increased by 6-8 times on the leeward north-west territories, where the accumulation of the toxicant was 2.5 times more pronounced than in the windward Eastern and North-Eastern side. The significant role in the deterioration of sanitary-ecological state of the territory of the sanitary protection zone when dealing with Hg-containing (70-100 mkg/kg) commodity grey belongs to reblowing of particles and their eolian spread from places of storage, loading and transportation. In separate halos the content of Hg in the soil has reached 285 mkg/kg and become closer to the "target" safe level (300 mkg/ kg), adopted in Western Europe (zone AGK-30 km). The total amount of metals as in the near (up to 5 km of sanitary protection), so far (5-50 km) zones as in background sites has increased steadily. By 2012 in some places, remoted up to 30 km from AGK there were fixed already hygienically dangerous levels of total metals accumulation (up to Zc =34)
