New Syrphidae (Diptera) of North-eastern North America

This paper describes 11 of 18 new species recognised in the recent book, "Field Guide to the Flower Flies of Northeastern North America". Four species are omitted as they need to be described in the context of a revision (three Cheilosia and a Palpada species) and three other species (one Neoascia and two Xylota) will be described by F. Christian Thompson in a planned publication. Six of the new species have been recognised for decades and were treated by J. Richard Vockeroth in unpublished notes or by Thompson in his unpublished but widely distributed "A conspectus of the flower flies (Diptera: Syrphidae) of the Nearctic Region". Five of the 11 species were discovered during the preparation of the Field Guide. Eight of the 11 have DNA barcodes available that support the morphology. New species treated in this paper include: Anasimyia diffusa Locke, Skevington and Vockeroth (Smooth-legged Swamp Fly), Anasimyia matutina Locke, Skevington and Vockeroth (Small-spotted Swamp Fly), Brachyopa caesariata Moran and Skevington (Plain-winged Sapeater), Brachyopa cummingi Moran and Skevington (Somber Sapeater), Hammerschmidtia sedmani Vockeroth, Moran and Skevington (Pale-bristled Logsitter), Microdon (Microdon) scauros Skevington and Locke (Big-footed Ant Fly), Mixogaster fattigi Locke, Skevington and Greene (Fattig's Ant Fly), Neoascia guttata Skevington and Moran (Spotted Fen Fly), Orthonevra feei Moran and Skevington (Fee's Mucksucker), Psilota klymkoi Locke, Young and Skevington (Black Haireye) and Trichopsomyia litoralis Vockeroth and Young (Coastal Psyllid-killer). Common names follow the "Field Guide to the Flower Flies of Northeastern North America" (Skevington et al. 2019).

A revision of the genus Orchestia Leach, 1814 with the reinstatement of O. inaequalipes (K.H. Barnard, 1951), the designation of a neotype for Orchestia gammarellus (Pallas, 1776) and the description of three new species (Crustacea: Amphipoda: Talitridae: Talitrinae)

Three New Species

The amphipod genus Orchestia is revised. It now includes 10 species of which three are new: O. forchuensis sp. nov. from north-eastern North America and Iceland., O. perezi sp. nov. from Chile and O. tabladoi sp. nov. from Argentina. Orchestia inaequalipes (K.H. Barnard 1951) is reinstated. The type species of the genus, O. gammarellus is redescribed based on material from Fountainstown, Ireland and a neotype is established to stabilize the species. The species was originally described from a garden in Leiden, far from the sea. Its true identity is unknown and no type material exists. Orchestia gammarellus (Pallas, 1776) is shown to be a sibling species group with members in both hemispheres of the temperate Atlantic as well along the Pacific coast of South America. A hypothesis for the establishment of the current distribution of Orchestia species is presented that extends back to the Cretaceous.

Nearctic Region

AbstractThe Nearctic fauna of the genus Calamoncosis Enderlein is reviewed. Five species are present in eastern North America: C. carncrossi Nartshuk was recently described from New York; the Palearctic species C. aprica (Meigen) and C. glyceriae Nartshuk are newly recorded, and two new species, C. brooksi and C. munda, are described from eastern North America. A sixth species present in the Nearctic Region is represented by one female specimen and is not identifiable. Most Nearctic specimens were collected in peatlands or marshes in Quebec, but there are scattered records from other grass-dominated habitats in Ontario, Manitoba, New York, and Texas. A key to the described species of Calamoncosis in the Nearctic Region is given.

History Of

The discovery of specimens of Tylopilus subg. Roseoscarbra in Australia prompted a comparative study of similar specimens from China, Japan, Costa Rica, and Eastern North America. The subgenus apparently originated in Laurasia. Populations of the subgenus migrated southwards from eastern Asia with their ectomycorrhizal hosts during Miocene/Pleistocene glaciations and subsequently adapted to different hosts in north-eastern Australia. The divergence in Australia is recognised in the new species: T. subchromapes, T. palumanus, T. queenslandianus, and T. propriorichromapes. Northern hemisphere populations disjuncted by the formation of the Atlantic Ocean are now recognised as new species in China — T. chlorinosmus, T. chromoreticulatus, and T. pinophilus — and in Japan, T. hongoi. During Pleistocene glaciation North American populations may have diverged in North and Central America that are recognised in Central America as T. cartagoensis and in North America as T. chromapes.
