Revision of Nearctic Dasysyrphus Enderlein (Diptera: Syrphidae).
Dasysyrphus Enderlein (Diptera: Syrphidae) has posed taxonomic challenges to researchers in the past, primarily due to their lack of interspecific diagnostic characters. In the present study, DNA data (mitochondrial cytochrome c oxidase sub-unit I—COI) were combined with morphology to help delimit species. This led to two species being resurrected from synonymy (D. laticaudus and D. pacificus) ...
متن کاملRevision of Nearctic Phthinia Winnertz (Diptera: Mycetophilidae).
The Nearctic species of Phthinia Winnertz are revised. Eight species are recognized, of which four are newly described; P. tanypus Loew (= P. carolina Fisher n. syn., and P. catawbiensis Shaw n. syn.), P. lobata Zaitzev, P. miranda Zaitzev, P. ramificans Zaitzev, P. nepunei n. sp., P. cascadica n. sp., P. meicigama n. sp. and P. mikmaqi n. sp. A key to these species is also provided.
متن کاملMolecular phylogeny of the Notostraca.
We used a combined analysis of one nuclear (28S rDNA) and three mitochondrial markers (COI, 12S rDNA, 16S rDNA) to infer the molecular phylogeny of the Notostraca, represented by samples from the six continents that are inhabited by this group of branchiopod crustaceans. Our results confirm the monophyly of both extant notostracan genera Triops and Lepidurus with good support in model based and...
متن کاملRevision of the Nearctic species of the genus Iphthiminus Spilman (Coleoptera: Tenebrionidae).
Nearctic species of Iphthiminus Spilman (Coleoptera: Tenebrionidae) are revised by examining external morphological structures and genital characters. Of the six Nearctic species, only three are considered valid: Iphthiminus serratus (Mannerheim 1843), I. opacus (Leconte 1866), and I. lewisii (Horn 1870). Photographs are taken to highlight structures and a key is created to identify the species...
متن کاملA revision of the Nearctic species of Liancalus Loew (Diptera, Dolichopodidae)

Seven species are documented from this region including two new species: Liancalusgenualis Loew, Liancalushydrophilus Aldrich, Liancaluslimbatus Van Duzee, Liancaluspterodactyl sp. n., Liancalusquerulus Osten Sacken, Liancalussimilis Aldrich, and Liancalussonorus sp. n. Lectotypes are designated for the following species: Liancalusgen...
