(En.) gladiator, E. (En.) loripedis, E. (En.) stenoptera and E. (En.) tridentata. A key to eastern species is presented and distributions illustrated. The form of nuptial gift presentation displayed within this group, including the use of balloons (with or without prey) and unwrapped prey are indicated for species when known.

The male genital tract of Axymyiidae and Tanyderidae, represented by Axymyia furcata McAtee and Protoplasa fitchii Osten Sacken, respectively, are described and illustrated for the first time. The tract of A. furcata is foreshortened, with relatively short, thick vasa deferentia that meet medially at the ejaculatory duct, which empties dorsal to the ejaculatory apodeme. The accessory glands are large and either firmly appressed or fused medially. The tract of P. fitchii has elongate vasa deferentia that curve ventrally and enter the ejaculatory duct separately. The short accessory glands are separate but their exit is uncertain. Neither of these male genital tracts shed further light on the phylogenetic position of these families within the nematocerous Diptera, although Tanyderidae do lack the synapomorphic multi-chambered accessory glands grouping Ptychopteridae + Culicomorpha + Bibionomorpha. © 2012 Entomological Society of Canada.

An unusual and undescribed genus and species of Axymyiidae known from a single specimen collected more than 50 years ago in Alaska is rediscovered in Mt. Rainier National Park (USA: WA). Based on two female specimens, Plesioaxymyia vespertina gen. nov., sp. nov. is described. A preliminary phylogenetic tree of the Axymyiidae is presented, showing Plesioaxymyia as sister group to all remaining axymyiid genera. Copyright © 2013 Magnolia Press.

Five species of Ragas from Baltic amber are described (R. baltica sp. nov., R. electrica sp. nov., R. eocenica sp. nov. R. succinea sp. nov., R. ulrichi sp. nov.). These are the first definitive fossil species of Ragas described. A key to species is provided and relationships of the fossil taxa to extant species are discussed.

Dolichocephala Macquart is revised for America, north of Mexico. New descriptions and diagnoses of the genus and a previously known species are presented. Six new species are described: Dolichocephala arnaudi sp. nov., Dolichocephala borkenti sp. nov., Dolichocephala chillcotti sp. nov., Dolichocephala teskeyi sp. nov., Dolichocephala vockerothi sp. nov., and Dolichocephala woodi sp. nov. Previous Nearctic records of Dolichocephala irrorata Fallén are based on misidentifications. Dolichocephala bellstedti Joost is newly recorded from Sweden. A key to adults, photographs of wings, illustrations of male terminalia, and known distributions are included. © 2012 Copyright Entomological Society of Canada.

Members of the megadiverse insect order Diptera (flies) have successfully colonized all continents and nearly all habitats. There are more than 154 000 described fly species, representing 10-12% of animal species. Elucidating the phylogenetic relationships of such a large component of global biodiversity is challenging, but significant advances have been made in the last few decades. Since Hennig first discussed the monophyly of major groupings, Diptera has attracted much study, but most researchers have used non-numerical qualitative methods to assess morphological data. More recently, quantitative phylogenetic methods have been used on both morphological and molecular data. All previous quantitative morphological studies addressed narrower phylogenetic problems, often below the suborder or infraorder level. Here we present the first numerical analysis of phylogenetic relationships of the entire order using a comprehensive morphological character matrix. We scored 371 external and internal morphological characters from larvae, pupae and adults for 42 species, representing all infraorders selected from 42 families. Almost all characters were obtained from previous studies but required revision for this ordinal-level study, with homology assessed beyond their original formulation and across all infraorders. We found significant support for many major clades (including the Diptera, Culicomorpha, Bibionomorpha, Brachycera, Eremoneura, Cyclorrhapha, Schizophora, Calyptratae and Oestroidea) and we summarize the character evidence for these groups. We found low levels of support for relationships between the infraorders of lower Diptera, lower Brachycera and major lineages of lower Cyclorrhapha, and this is consistent with findings from molecular studies. These poorly supported areas of the tree may be due to periods of rapid radiation that left few synapomorphies in surviving lineages. © 2012 The Royal Entomological Society.

Bezzi described two species in Apalocnemis Philippi, which at that time was placed in Empididae. This genus is presently assigned to Brachystomatidae, Trichopezinae. The type specimen of A. variegata Bezzi, 1905 is lost. Apalocnemis cingulata Bezzi, 1909 is redescribed and a lectotype designated based on a male specimen from Sicuani, Peru.
