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.

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.

By using morphology, karyology, pollen size, leaf flavonoids, ecological observations, and modification experiments, a new classification of the Galium trifidum group is proposed. Nine taxa in five species are recognized: (1) G. tinctorium, with ssp. tinctorium and sap. floridanum (new comb.) in eastern North America; (2) G. brevipes, a rare species centered in the Great Lakes region; (3) G. trifidum, with ssp. trifidum in northern North America. Asia, and Europe, ssp. columbianum (new comb.) in (north)western North America and (north)eastern Asia, and ssp. subbiflorum (new comb.) and ssp. halophilum (new comb.) in northern North America; (4) G. innocuum in southeastern Asia; (5) G. karakulense in central Asia.New chromosome counts of n = 12 and 2n = 24 are reported for G. tinctorium ssp. tinctorium and ssp. floridanum; and G. trifidum ssp. trifidum, ssp. columbianum, and ssp. subbiflorum.

Biogeographic Analysis

AbstractThe genus Eudasyphora Townsend 1911 is resurrected from junior synonymy and recognized with the genera Dasyphora Robineau-Desvoidy 1830 and Pyrellia Robineau-Desvoidy 1830. Rypellia Malloch 1932 is a subgenus of Eudasyphora, but Dasypyrellia Lobanov 1976 is reported as synonym novum. A key to the species of Eudasyphora is presented. Two new species are described: E. cordilleriana n. sp. from western North America, and E. canadiana n. sp. from northern North America. The phylogenetic and biogeographic analysis led to the following conclusions: Eudasyphora became separated from its sister genus Pyrellia before the beginning of the Pleistocene glaciations. The Rypellia line evolved further in the Oriental Region, whereas the Eudasyphora s. str. line developed in the Holarctic Region. Speciation in both subgenera is correlated with the history of the forest vegetation during the Pleistocene.

Abstract This study integrates biogeographical and phylogenetic data to determine the evolutionary history of the New World Dermacentor, and the origin of D. variabilis. The phylogenetic reconstructions presented here strongly support the hypothesis of an Afrotropical origin for Dermacentor, with later dispersal to Eurasia and the Nearctic. Phylogenetic and biogeographical data suggest that the genus reached the New World through the Beringia land bridge, from south-east Asia. The monophyly of the genus is supported, and most of the New World Dermacentor species appear as monophyletic. Dermacentor occidentals constitutes the sister lineage of D. variabilis, and the latter is subdivided into two well-supported clades: an eastern and a western clade. The western clade is genetically more variable than the eastern. The genus Dermacentor probably originated in Africa, and dispersed to the Palearctic and then to the New World through the Beringian route. Dermacentor variabilis appears to have originated in western North America, and then dispersed to eastern North America, probably in a single migration event.

REVISION OF THE CHIGGER-LIKE LARVAE OF THE GENERA NEOTROMBIDIUM LEONARDI AND MONUNGUIS WHARTON, WITH A REDEFINITION OF THE SUBFAMILY NEOTROMBIDIINAE FEIDER IN THE TROMBIDIIDAE (ACARINA: PROSTIGMATA)

AbstractThe trombidiid subfamily Neotrombidiinae Feider is re-established and redefined, based primarily on larval characters but also on adult characters. It is closely related to the trombidiid Trombellinae on the one hand and to the Leeuwenhoekidae on the other. It consists of two genera, namely Monunguis Wharton, which is monobasic and known only from the larva, and Neotrombidium Leonardi, with 13 described species of which 7 are known from the larva and 8 from the adult (the larva and adult of 2 species are correlated by rearings).The history of the family-level placement of this group, and the controversy over whether or not to recognize two genera, are reviewed. The characters that justify the separate recognition of Monunguis and Neotrombidium are enumerated.The larva of each of the following species of Neotrombidiinae is described, illustrated and keyed: Monunguis streblida Wharton from the Caribbean area, Neotrombidium barringunense Hirst from Australia, N. tricuspidum Borland from North America, N. tenuipes (Womersley) from Malaya, N. samsinaki (Daniel) new combination from central Europe, N. anuroporum new species from Central America, N. bengalense new species from India, and N. tenebrione new species from eastern North America. Six other species of this group, known only from the adult, are listed separately but are not treated taxonomically here.The larvae of Neotrombidiinae parasitize adult insects: those of Monunguis are hyperparasites on streblid flies whereas those of Neotrombidium are ectoparasites of cerambycid, clerid, elaterid, and tenebrionid beetles that pass part of their life history under the bark of trees.In the Microtrombidiinae, Camerotrombidium Thor is noted as the valid replacement name for the preoccupied Ottonia Kramer.

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 New Species

A new species of the ptilodontid multituberculate genus Prochetodon (Mammalia, Allotheria) from the Paleocene Paskapoo Formation of Alberta, Canada, is described. Prochetodon speirsae sp. nov. is the oldest discovered species of the genus, extending the temporal range of Prochetodon earlier into the Paleocene. It exhibits a mosaic of primitive and derived dental features suggestive of a position phylogenetically intermediate between Ptilodus and Prochetodon. Newly discovered specimens from the late Paleocene Gao Mine locality are referred tentatively to Prochetodon foxi. The occurrence of a primitive form of Prochetodon in sediments of early Tiffanian age suggests the evolutionary history of the genus is more complex than previously appreciated. Prochetodon joins a number of well-documented, progressive mammalian taxa making their first appearance in the Western Interior of North America at higher latitudes, well before their first known occurrence in the United States, suggesting a possible origin and immigration from currently unsampled habitats.

AbstractThe species of the genus Lordithon Thomson (Staphylinidae: Tachyporinae) of North and Central America are revised. Thirty-seven species are recognized. Sixteen new species are described: scutellaris, appalachianus and notabilis from eastern North America; difficilis and oregonus from the Pacific Northwest; fungicola transcontinental in North America; and nubicola, dubius, newtoni, howdeni, ashei, hidalgoensis, antennatus, consors, blandus, and oreophilus from Mexico. The following species names are placed in synonymy: cascadensis hatchi Malkin (= cascadensis Malkin); cincticollis Say (= thoracicus thoracicus Fabricius); occiduus Casey (= thoracicus thoracicus Fabricius); alticola Sharp (= obliquus Sharp); kelleyi Malkin (= bimaculatus Couper) and elefas Bernhauer (= longiceps LeConte). L. venustus Melsheimer is reduced to a subspecies of thoracicus Fabricius. The species festivus Sharp, obliquus Sharp, smithi Bernhauer, and mexicanus Bernhauer are transferred to Lordithon from the genus Bolitobius. Lordithon lunulatus is doubtfully recorded from North America for the first time.The usage of the generic group names Lordithon Thomson, Bolitobius Samouelle, Megacronus Stephens, Bryocharis Boisduval and Lacordaire, Carphacis des Gozis, and Bolitobus Tottenham is discussed. The genus Lordithon is divided into two subgenera, Lordithon Thomson and Bolitobus Tottenham (not Bolitobius Samouelle). The male aedeagus and other major diagnostic characters are illustrated and the distribution of each species mapped.The species rubescens Hatch, varions Hatch, fenderi Hatch and biseriatus Mannerheim are transferred from Lordithon to the genus Bryoporus Kraatz.Lectotypes are designated for the following species: niger Gravenhorst, axillaris Gravenhorst, festivus Sharp, anticus Horn, poecilus Mannerheim, facilis Casey, arizonensis Bernhauer, obliquus Sharp, alticola Sharp, smithi Bernhauer, mexicanus Bernhauer, cinctus Gravenhorst, gentilis LeConte, elefas Bernhauer and rostratus LeConte. Neotypes were designated for: angularis Sachse, trimaculatus Say, cincticollis Say, obsoletus Say and atricaudatus Say.
