A Revision of the Nearctic Species of the Genus Trixoscelis Rondani (Diptera: Heleomyzidae: Trixoscelidinae)
Author: George Arnold FosterPublisher:
ISBN:
Category : Diptera
Languages : en
Pages : 140
Book Description
The Nearctic species of the genus Trixoscelis Rondani are revised. Thirteen new species are described, seven new combinations and three new synonyms are proposed, and three species groups are characterized. Keys to the 38 known species are provided. Diagnoses, detailed distributional data for the species of the genus, notes on the biology, and illustrations (photographs and drawings) are included to assist species identification. A phylogenetic analysis was performed to test the monophyly of the genus Trixoscelis and the included species groups. The ingroup includes a total of 38 exemplar species. Outgroup sampling includes the following exemplar genera: Neossos, Waterhousea, Fenwickia, Aneuria, and Xenura. Analyses, including implied weighting, recovered a monophyletic Trixoscelis and species groups if the Mongolian genus Paratrixoscelis is included within Trixoscelis.
A revision of the New World species of Gymnoclasiopa Hendel (Diptera, Ephydridae)
Author: Wayne N. MathisPublisher: PenSoft Publishers LTD
ISBN: 9546426601
Category : Science
Languages : en
Pages : 76
Book Description
This revision comprehensively documents the New World species of the shore-fly genus Gymnoclasiopa, which primarily has a Holarctic distribution, including some species that are found in both the Nearctic and Palearctic Regions. Discovering additional species common to both biogeographic regions was an objective of this study, as was unraveling any nomenclatural issues that resulted when the same species was described separately in both biogeographic regions. Ten species are treated, including two that are newly described. The authors also document the obvious sexual dimorphism that is evident in some species but which was not previously appreciated, resulting in confused concepts of some species. The authors emphasize structures of the male terminalia, which are fully described and illustrated, in the recognition of species. In addition, detailed locality data and distribution maps for all species are provided. Much of this increase has resulted from a greatly improved sampling of the New World fauna, documenting the ongoing need for field work and better taxon sampling of the earth?s shore-fly fauna.
A revision of the new world species of Polytrichophora Cresson and Facitrichophora, new genus (Diptera, Ephydridae)

Pages : 122
Book Description
This revision significantly documents a continuing trend in the discovery and documentation of New World shore flies (Diptera: Ephydridae). Two genera of the tribe Discocerinini are treated: Facitrichophora, new genus, with all four included species being newly described, and Polytrichophora Cresson with 19 species, including 11 that are newly described. Previously, eight species were known from the New World. The authors emphasize structures of the male terminalia, which are fully described and illustrated, in the recognition of species and species groups. In addition, detailed locality data and distribution maps for all species are provided. Much of this increase has resulted from a greatly improved sampling of the New World fauna, which documents an ongoing need for field work and better taxon sampling of earth?s shore-fly fauna.
A revision of the shore-fly genus Hydrochasma Hendel (Diptera, Ephydridae)
Author: Wayne N. MathisPublisher: PenSoft Publishers LTD
ISBN: 9546427098
Category : Science
Languages : en
Pages : 167
Book Description
This revision comprehensively documents species of the shore-fly genus Hydrochasma Hendel, which is one of three genera of the shore-fly tribe Discocerinini (subfamily Gymnomyzinae) that occurs exclusively in the New World. The other two genera are Pectinifer Cresson and Facitrichophora Mathis & Zatwarnicki. All known species of Hydrochasma are described with an em-phasis on structures of the male terminalia, which are fully de-scribed and illustrated. In addition, detailed locality data and dis-tribution maps for all species are provided. Among New World genera of Discocerinini, Hydrochasma is perhaps the least well known, as indicated by the dramatic increase in recognized species reported in this revision. Before this revision, Hydrochasma included just seven species, and herein we more than quadruple that number by adding 27 previously undescribed species. These additions bring the total number of congeners to 34. Much of this increase has resulted from a greatly improved sampling of the New World fauna, documenting the ongoing need for field work and better taxon sampling of the earth?s shore-fly fauna. With clarification of species ? how they can be recognized and where they occur ? we hope that additional research on immature stages and other aspects of their natural history and ecol-ogy will be fostered and facilitated.
A revision of the genus Planinasus Cresson (Diptera, Periscelididae)

Languages : en
Pages : 92
Book Description
The New World species of the subgenera Allotrichoma Becker and Neotrichoma (new subgenus) (genus Allotrichoma) are revised. For phylogenetic perspective to this revision, we studied all genus-group taxa within the tribe Hecamedini and reassessed their cladistic relationships. Our phylogenetic study for taxa within the genus Allotrichoma was done at the species-group level, and we attempted to approach this globally by examining species from throughout the world and placing them into appropriate species groups. Within Allotrichoma, we recognize three subgenera. All known species from the New World are described with an emphasis on structures of the male terminalia, which are fully illustrated. We more than double the number of species known from the New World with six of 12 species in the subgenus Allotrichoma being described herein, and in a newly described subgenus, Neotrichoma, two of the three species from the New World are also described
