AbstractThe subgenus Chrysocharis s. str. in America north of Mexico consists of 18 species. Of these, six are new: Chrysocharis beckeri, subcircularis, bellincus, clarkae, truncatipennis, and levipectus. The name giraulti is proposed for petiolata Girault nec Förster. Key to species, descriptions, host records, and illustrations are included. Relationships of species-groups of North America and Europe are discussed.

The species of Ceraturgus occurring in the eastern United States and Canada are reviewed. A key to species, descriptions, illustrations of wings and some genitalic features, and distribution maps are presented. Ceraturgus fasciatus is resurrected from synonymy with Ceraturgus cruciatus, and Ceraturgus mabelae is reduced to synonymy with Ceraturgus nigripes (new synonymy). Ceraturgopsis is resurrected, assigned subgeneric rank, and Ceraturgus cornutus is fixed as type species. This work is dedicated to the memory of one of America’s foremost asilidologists, Joseph Wilcox.

AbstractThis study examines the seven described species ofEpiphragmaOsten Sacken (Diptera: Tipulidaes.l.) known to occur in North America including Mexico. A key to species, descriptions, distributional ranges, habitat information, and literature references are given and the wing patterning and male genitalia are illustrated. The male ofEpiphragma celatorAlexander is described for the first time and the species range is extended north from Michoacan, Mexico to southern Arizona, United States of America. The range ofEpiphragma arizonenseAlexander is extended from southern Arizona south to Sinaloa, Mexico. The male hypopygium ofEpiphragma nebulosum(Bellardi) and wing and hypopygium ofEpiphragmaoreonymphaAlexander are illustrated for the first time.

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.

Morphology of the intercostal palea region of 34 Festuca species found in North America was investigated using scanning electron microscopy. Palea epidermal features are most diverse in the palea apical region and fully developed in florets approaching anthesis. The intercostal region has long cells 3–15 times longer than wide, with walls that vary from slightly to prominently thickened, and from almost straight to strongly undulate. This variation was observed among paleas collected from different locations and sometimes even on a single palea. The distribution of short cells, almost square in outline, among the long cells varied with species from solitary to paired and from abundant to sparse. Four forms of trichomes were recorded: papillae, hook trichomes, prickle hairs, and macrohairs, with one form usually predominating per species. Silicon was detected in some short cells and commonly in the tips of trichomes. A key to species groups is presented. Key words: scanning electron microscopy, palea, trichomes, silicon, epidermal features, Festuca.

The genus Systenus Loew, 1857 is recorded from Afrotropical Region for the first time. A description of a new species, Systenus africanus Grichanov sp. nov., and notes on females of another probably new Afrotropical species are provided. The genus is considered now as cosmopolitan. A key to species and species groups of the Systenus worldwide is compiled.

Species within Gennadas differ from each other largely only in male (petasma) and female (thelycum) copulatory characters, which were restudied in scanning electron microscopy and used as a basis for phylogenetic analyses. Twenty-six petasma characters and 49 thelycum characters were identified. All 16 recognized species of Gennadas and Aristaeomorpha foliacea (outgroup) were included as terminals. Four robust monophyletic clades were retrieved, described and diagnosed as new species groups. The thelycum characters had greater impact on tree topology and supported deeper nodes than did the petasma characters. We hypothesize that features of the thelycum evolved first followed by aspects of the petasma. Relatively more conservative characters include parts of the sternites of the thelycum and of the petasma, while the scuti and protuberances on the thelycum and the shape and subdivisions of the petasma lobes are evolutionarily plastic. We identified two groups of copulatory characters, which are likely coupled functionally and interlinked evolutionarily: (i) the external part of the petasma and the posterior part of the thelycum and (ii) the internal part of the petasma and anterior part of the thelycum. We reconstruct possible mating position during copulation for each of the new species groups presented here. We also present an updated key to genera of Benthesicymidae and key to species of Gennadas .

We examined the morphology of the genitalia and cuticular scales of eight species of Australian lynx spiders of the genus Oxyopes and compared them with those of representative species from Africa, Asia and North America. Our results indicate that the eight species examined are representative of two distinct species groups of Oxyopes in Australia. The first group consists ofO. amoenus, O. dingo, O. gracilipes, O. molarius, O. rubicundus, and O. variabilis. The evolutionary origin of these spiders is difficult to discern as they share multiple genitalic characters with African and Asian taxa. However, these six species display two characters, leg scales and internal cuticular elements in the opisthosomal scales, that are exhibited by African, but not Asian, taxa. The second group consists of Oxyopes macilentus and O. papuanis. These taxa exhibit many of the same morphological features, exhibited by Asian, but not African, species.

AbstractThe systematics of Acalymma sensu stricto of North America including Mexico are revised. Acalymma sensu stricto is defined and distinguished from the other species groups of Acalymma. Sixteen species are discussed including four new species: A. blomorum, A. palomarense, A. invenustum, and A. luridifrons all from Mexico. Three new subspecies of A. blandulum (LeConte) are described: blandulum (LeConte) new status, nigriventre, and yucatanense. Acalymma coruscum costaricense Bechyné is placed as a synonym of A. innubum (Fabricius). Keys are presented to all species and subspecies. Habitus and male genitalia drawings are given for all species and distribution maps are given where appropriate.

An account of the Drepanolejeunea subgenus Rhaphidolejeunea in Thailand has been updated based on herbarium specimens and recent collections from field surveys. Five species of Drepanolejeunea, i.e. Drepanolejeunea commutata, D. fleischeri, D. siamensis, D. spicata, and D. yunnanensis are recognized. Of these, Drepanolejeunea commutata, D. fleischeri, and D. yunnanensis are newly reported for Thailand. A key to species, descriptions, distribution ranges and illustrations of each species are provided. The ecology and geographical distribution of the species are noted. Additionally, Drepanolejeunea longicruris is excluded from the country.
