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. Source

(En.) cacuminifer Melander = E. (En.) gulosa. Lectotypes are designated for the following species: E. (En.) arthritica, E. (En.) cacuminifer, E. (En.) ctenonema, E. (En.) enodis, E. (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.

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. Source

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.
