AbstractThe name Enaysma Delucchi, 1954 is synonymized with the name Achrysocharoides Girault, 1913. Achrysocharoides is divided into two species-groups, guizoti and gahani. Fifteen North American species are recognized, including five that are new: A. reticulatus, A. bisulcus, A. albus, A. tetrapunctatus, and A. intricatus. A key to species, host lists, and distributions are included.

Diving Beetle

AbstractThe first of a planned series of papers revising the Nearctic species of the predaceous diving beetle genus, Agabus Leach, is presented. The genus is defined in the broad sense of Sharp (1882) and Fall (1922). The North American species are divided into species groups and diagnostic characters for group recognition are summarized in a key. Assignment of species to these groups is indicated in a checklist of North American species. The ambiguus-, tristis-, and arcticus-groups are defined, their relationships discussed, and included species revised. The ambiguus-group, which is restricted to North America, contains the species A. ambiguus (Say), A. strigulosis (Crotch), A. erythropterus (Say), A. austinii Sharp, and A. klamathensis sp.nov. The tristis-group, which has a Holarctic distribution, contains two species in North America, A. tristis Aubé and A. leptapsis (LeConte). The Holarctic arcticus-group is represented by A. arcticus (Paykull) and A. anthracinus (Mannerheim) in North America. For each species, patterns of variation are described, the North American distributions mapped, and ecological information summarized.

AbstractThe North American species of Dicladocerus are revised. Twelve new species from North America and one from Japan are described and illustrated: alaskensis, australis, prealatus, occidentalis, exoteliae, epinotiae, betulae, vulgaris, nearcticus, pacificus, japonicus, and terraenovae. The species attacking larch casebearer are nearcticus, pacificus, terraenovae, all Nearctic, and japonicus and westwoodii, Palaearctic. Relationships of species-groups in North America are discussed. A key to species, and host records are included.

AbstractThe sexes of all but three of the North American species of Ips DeGeer can be separated reliably using characters on the frons, vertex of the head, protibiae, or declivital armature. In general, these secondary sexual characters are consistent within Hopping’s species groups.

A New Species

A new species of acarid mite, Naiadacarus sidorchukae sp. n., is described from phoretic deutonymphs collected from a European spruce bark beetle, Ips typographus, pheromone trap in Western Siberia, Russia. Morphologically, the new species is very similar to the North American species, Naiadacarus fashingi, with the only diagnostic character being the shorter tibial solenidion φ II in the former species. Unlike some Naiadacarus species, which are truly aquatic, Naiadacarus sidorchukae probably does not inhabit fully aquatic habitats. This species and other presumably non-aquatic taxa, may represent the ancestral condition in the genus Naiadacarus, and, therefore are critical in studying land to water ecological transitions that have occurred in this mite genus. The monotypic genus Naiacus Nesbitt, 1990 is considered as a junior synonym of Naiadacarus Fashing, 1974 (syn. n.), with its type-species, Naiacus muertensis Nesbitt, 1990, recombined as Naiadacarus muertensis (Nesbitt, 1990), comb. n. A key to species of Naiadacarus of the world is provided

AbstractThe 50 known species of North American Clubiona Latreille, 1804 are rearranged in seven species-groups as follows: trivialis group (1 Holarctic, 4 Nearctic), obesa group (11 Nearctic), reclusa group (2 Holarctic, 3 Nearctic), pallidula group (1 Holarctic), abboti group (25 Nearctic), lutescens group (1 Holarctic, 1 Nearctic), maritima group (1 Nearctic). Clubiona quebecana and C. angulata are described as new species from eastern North America. C. kuratai Roddy, 1966, originally described from the female only, is synonymized under C. chippewa Gertsch, 1941, which was originally described from the male only. C. opeongo Edwards, 1958 and C. bishopi Edwards, 1958 are redescribed, the male of the former and the female of the latter not having been previously described.

Velvet Ant

The velvet ant genus Invreiella Suárez, 1966 is redescribed and revised. Females are grouped into five species-groups, with eleven new species described based on females: I. acuminata Waldren, sp. nov., I. australis Waldren, sp. nov., I. bimaculata Waldren, sp. nov., I. breviclypeata Waldren, sp. nov., I. chihuahuensis Waldren, sp. nov., I. cuernavaca Waldren, sp. nov., I. erythrocephala Waldren, sp. nov., I. manleyi Waldren, sp. nov., I. mesomexicana Waldren, sp. nov., I. suarezi Waldren, sp. nov., and I. tequila Waldren, sp. nov. One new combination is included, I. cephalargia (Mickel, 1924), comb. nov., formerly placed in Pseudomethoca Ashmead, 1896. Additionally, I. curoei Quintero & Cambra, 2011 is synonymized with I. cardinalis (Gerstaecker, 1874), syn. nov., and I. megacantha (Cockerell & Casad, 1894), stat. resurr., is treated as a nomen dubium. The lectotype of Mutilla satrapa Gerstaecker, 1874 originally designated by C. Mickel is here validated. An illustrated key to species is included.

AbstractThe species of the genus Sepedophilus (Staphylinidae: Tachyporinae) of America north of Mexico are revised. Thirty species are recognized. Thirteen new species are described: wickhami from the northeastern United States and southeastern Canada; brachypterus, frosti, micans, ctenidialis, and kiteleyi from eastern North America; beckeri from the southcentral United States; and hermani, smetanai, stephani, arizonensis, coronadensis, and velox from the southwestern United States. The following species names are placed in synonymy: knoxii LeConte and carissimus Hatch (= littoreus Linnaeus); imbricatus Casey, limuloides Casey, and elongatus Blatchley (= testaceus Fabricius); corticola Casey (= cinctulus Erichson); virginiae Casey (= velocipes Casey); and subtilis Casey (= debilis Casey). The species cinctulus Erichson and bisignatus Horn, formerly considered as synonyms of opicus Say and bipustulatus Fabricius respectively are recognized as valid species. The Palearctic species marshami Stephens is reported for the first time from the Nearctic region. The usage of the generic group names Sepedophilus Gistel, Conurus Stephens, Conosoma Kraatz, and Conosomus Motschulsky is discussed. The North American species are divided into 12 species groups based on an examination of the Nearctic, Neotropical, and Palearctic faunas. The distribution of each species is mapped, and the male and female eighth abdominal sternites and tergites, the male genitalia and other diagnostic characters, are illustrated. A neotype is designated for Tachyporus opicus Say, and lectotypes are designated when necessary for all the North American species of Sepedophilus described by Gravenhorst, Erichson, LeConte, Horn, and Casey. A diagnostic key for all the species except S. heathi Wasmann is given. A brief discussion of the nomenclatural history of the genus, of collecting techniques, and of the major diagnostic characters is included.

AbstractA key to species for adults and figures of the three North American Cinygma are presented. New distribution records are given; the range of C. lyriformis McDunnough is extended to Alaska and the genus in the Palearctic is discussed. Nymphs are undescribed except for C. integrum (Eaton). The life history of the latter is given for Oregon. Nymphs of all size classes are present throughout the year but adult emergence is restricted to mid May to mid July. Nymphs apparently are restricted to a submerged wood habitat.

Four species of Cicuta (family Umbelliferae) are recognized for North America: C. maculata L. (2n = 22), C. douglasii (DC.) Coult. & Rose (2n = 44), C. virosa L. (2n = 22), and C. bulbifera L. (2n = 22). Cicuta maculata has 22 large somatic chromosomes, C. virosa has 22 small somatic chromosomes, C. bulbifera has 22 medium sized chromosomes, and C. douglasii has 22 large chromosomes and 22 small chromosomes. Four varieties of C. maculata are recognized: var. maculata, var. angustifolia Hook., var. victorinii (Fernald) Boivin, and var. bolanderi (S. Wats.) G. A. Mulligan, stat. nov. Cicuta mackenzieana Raup is considered conspecific with C. virosu. The nomenclature, distribution, and relationships of the North American species are given together with an identification key to species and varieties.
