The genusXanthogrammaSchiner, 1861 (Diptera: Syrphidae) in southeastern Europe, with descriptions of two new species

Abstract

Examination of 122 specimens ofXanthogrammaSchiner, 1861 (Diptera: Syrphidae) from varied localities in Europe (+Turkey) resulted in the description of two new species (X. aeginaeRicarte, Nedeljković, and Vujićnew speciesandX. pilosumNedeljković, Ricarte, and Vujićnew species), as well as new data on six other species. Most of the examined material originated from the Balkan Peninsula and Greek islands. New species concepts were supported by morphological and molecular evidence. Relationships among the eight studied species were analysed and discussed based on the data of nuclear (ITS2) and mitochondrial (COI) genes sequences. An identification key to the European species ofXanthogrammais provided. Lectotypes are designated forDoros decoratumZetterstedt, 1843,Lasiophthicus novusRondani, 1857,Syrphus laetusFabricius, 1794,Syrphus ornatusMeigen, 1822, andXanthogramma nobilitatumFrey, 1946.

Life on an island: the phylogenetic placement ofLoveridgeanaand AfrotropicalSphaerophoria(Diptera: Syrphidae) inferred from molecular characters

“…In our study, although we used longer COI sequences than the standardized DNA barcode, the uncorrected pairwise distances (p-dist) between some studied Sphaerophoria species was zero [e.g., between S. assymetrica Knutson, 1942 andS. taeniata (Meigen, 1822) Schiner, 1860 (Haarto & Ståhls, 2014), Merodon Meigen, 1803 (Mengual, Ståhls, Vujić & Marcos-García, 2006;Ståhls et al, 2009), Xanthogramma Schiner, 1860 (Nedeljković et al, 2018), and in some Afrotropical species and genera (Jordaens et al, 2015). The nuclear 28S rRNA gene behaves similar to COI for Sphaerophoria and the nuclear 18S rRNA gene is too conservative to distinguish among closely-related species of Sphaerophoria (Supplement 3; both rRNA genes with gaps in the alignment).…”

Checklist of hover flies (Diptera, Syrphidae) of the Republic of Georgia

“…Remarks. As shown by Nedeljković et al (2018: fig. 40), X. dives, X. stackelbergi and X. pedissequum share some COI haplotypes and the separation of these taxa using barcoding is not straightforward.…”

Integrative taxonomy confirms two new West-Palaearctic species allied with Chrysotoxum vernale Loew, 1841 (Diptera: Syrphidae)

“…Protocols for DNA extraction, PCR amplification and sequencing of 3'COI and ITS2 regions are described in Nedeljković et al (2018b). The newly-produced DNA sequences were edited for base-calling errors using BioEdit version 7.2.5.…”
