      A new epoch in the Nearctic zerconid systematics was opened by Halašková's revision of the family in the Canadian region (Halašková ). In this revision she critically examined all zerconid species described previously and provided descriptions of four new genera and nine new ://   Abstract. The family Paeromopodidae is comprised of large, agile millipeds that include the longest diplopods in the Nearctic. It is endemic to three regions in the western United States - a large, irregular area extending from the southern Sierra Nevada Mountains and the Monterey Peninsula of California to the northern Puget Sound region of Washington, a small, ovoid area in the Warner ?lang=en.

    The genus Gonioctena Chevrolat, with about described species in nine subgenera is one of the largest genera within the subfamily Chrysomelinae (Cho and Borowiec ).The nominotypical subgenus is the largest and contains 47 species that are widely distributed in the Holarctic and Oriental regions (Cho ).Many species of the nominotypical subgenus have received much attention due ?id=   Presented is an annotated catalog of the 38 genera and species of Leiodidae known to occur in the Nearctic Region of North America north of Mexico (the continental USA and Canada). Information on types, distributions, and biologies is included. Twelve of the species also or probably occur in Mexico, and 16 of the species also occur in Europe and/or Asia (i.e., are Holarctic in distribution

While most pompilids follow this general pattern of behaviour, in the Nearctic region wasps of the genus Evagetes and the subfamily Ceropalinae exhibit cleptoparasitism (Evans ). In these groups the female uncovers the buried spider of another pompilid and deposits her own egg in the book lungs of the :// of BC_Finalpdf. The classification of the largest subfamily of leafhoppers, Deltocephalinae, including 38 tribes, genera, and valid species, is reviewed and revised. An updated phylogeny of the subfamily based on molecular (28S, Histone H3) and morphological data and an expanded taxon sample (37 taxa not included in previous analyses) is

A revision of the hydrophilid subfamily Helophorinae (Coleoptera), containing the single genus Helophorus Fabriciusis presented, including an historical review, a discussion of diagnostic characters and techniques, and an attempt at a phylogenetic reconstruction of the major lineages of the Nearctic -one species are recognized; 9 species and 1 subspecies are described as Revision of the subfamily Helophorinae of the Nearctic Region (Coleoptera, Hydrophilidae).

Ottawa, Ont.: Entomological Society of Canada, (OCoLC) Document Type: Book: All Authors / Contributors: Aleš Smetana In this revision, 46 species of Fannia, and one each of Euryomma and Piezura are described as new. The present study is concerned with all the species of the subfamily that occur in the Nearctic region, which is here interpreted as extending throughout North America south to the limits of the Mexican :// The species of the subfamily Eucharitinae (which parasitize ants) are revised, and keys are provided for the 5 genera of Eucharitidae and 16 described species of Eucharitinae of the Nearctic Region.

They are the largest insects in the order Hemiptera. There are about species found in freshwater habitats worldwide, with more than in the Neotropics, more than 20 in Africa, almost single subfamily of a single genus, Helophorus.

This genus comprises about species of wich about occur in the Palearctic (). There are 41 species known in the Nearctic (4), 10 of which are Holarctic in distribution.

The family Paeromopodidae is comprised of large, agile millipeds that include the longest diplopods in the Nearctic.

It is endemic to three regions in the western United States - a large, irregular area extending from the southern Sierra Nevada Mountains and the Monterey Peninsula of California to the northern Puget Sound region of Washington, a small, ovoid area in the Warner ?language=en.

The main causes and degree of inaccuracy of air temperature reconstruction by the MCR method are discussed. This inaccuracy appears to result from several reasons: insufficient knowledge of geographic ranges of species, the use of calibration equations calculated for a different region, and the absence of generally accepted criteria for the selection of species to be used in MCR analysis, in.

The subfamily Triatominae is restricted to the Nearctic, Neotropical, and Oriental regions, entering the Australian region marginally. Triatoma rubrofasciata is tropicopolitan. There are 13 genera in the Western Hemisphere, with the center of diversity in South This publication presents illustrated keys to the 19 families and described genera of Chalcidoidea known to occur in the Nearctic region (minimally America north of Mexico, but also including those areas of Mexico generally considered as having a Nearctic insect fauna).
