Aspects of European Argyra systematics: molecular insights and morphology (Diptera: Dolichopodidae)


Germann, Christoph; Pollet, Marc; Bernasconi, Marco V (2011). Aspects of European Argyra systematics: molecular insights and morphology (Diptera: Dolichopodidae). Entomologica Fennica, 22(1):5-14.

Abstract

We focused on systematic aspects of some of the most common European Argyra species. Bayesian and Maximum Parsimony analyses were performed, using three mitochondrial markers (COI, 12S, and 16S) with ten Argyra species as the ingroup, and three other Diaphorinae as an outgroup. The topology of the trees derived from the two analyses was slightly different but not conflicting and allowed the identification of five species groups corroborated by morphological characters. The Argyra argyria species group and the Argyra atriceps species group encompass the majority of the species and can be regarded as Argyra sensu stricto. The Argyra diaphana species group is characterized by a pubescent scutellum, a characteristic of Lasiargyra. The Argyra elongata species group has previously always been regarded as Argyra s.s., but consistently clustered separately from this clade in our analyses. The Argyra vestita species group corresponds with Leucostola, and is characterized by a bare scape.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
