Review of New World Sericomyia (Diptera: Syrphidae), including description of a new species

  • Jeffrey H. Skevington (a1) and F. Christian Thompson (a2)
Abstract
Abstract

The 19 New World species of Sericomyia Meigen are reviewed, including one species new to North America (Sericomyia jakutica (Stackelberg)) and one previously undescribed species (Sericomyia vockerothi Skevington sp. nov. from Alberta, Minnesota, Northwest Territories, Quebec, and Yukon Territory). Mallota powelli Nayar and Cole is recognized as a junior synonym of Sericomyia flagrans (Osten Sacken). A description and illustrations of S. vockerothi and an illustrated key to New World Sericomyia are presented. DNA barcode data are presented for 14 New World species and a cytochrome oxidase subunit I gene tree is presented and discussed. Genetic evidence supports the contention that the subgenera of Sericomyia are not monophyletic. Arctophila Schiner and Conosyprhus Frey are thus proposed as junior synonyms of Sericomyia.

Résumé

Nous révisons les 19 espèces de Sericomyia Meigen du Nouveau Monde, y compris une espèce signalée pour la première fois en Amérique du Nord (Sericomyia jakutica (Stackelberg)) et une espèce encore non décrite (Sericomyia vockerothi Skevington sp. nov. d'Alberta, du Minnesota, des Territoires du Nord-Ouest, du Québec et du territoire du Yukon). Mallota powelli Nayar et Cole devient un synonyme plus récent de Sericomyia flagrans (Osten Sacken). Nous présentons une description et des illustrations de S. vockerothi, ainsi qu'un clé illustrée pour l'identification des Sericomyia du Nouveau Monde. Des données sur les codes à barres génétiques sont fournies pour 14 espèces du Nouveau Monde, de même qu'un arbre génique de la CO1 qui fait l'objet d'une discussion. Les données génétiques appuient la proposition que les sous-genres de Sericomyia ne sont pas monophylétiques. Nous proposons donc Arctophila Schiner et Conosyrphus Frey comme synonymes plus récents de Sericomyia.
