Revisions of the and species groups of the genus Meigen, 1803 (Diptera, Syrphidae).

This study focuses on the lineage within the genus , exploring morphological, genetic, and distributional aspects of two related assemblies within this lineage: the and species groups. An integrative taxonomic approach was followed to ensure comprehensive species identification and validation, using adult morphology, wing geometric morphometrics, and genetic analysis of the mtDNA COI gene. In the group, seven species were identified, including three new species: Vujić, Radenković & Likov, , Vujić, Radenković & Likov, , and Vujić, Radenković & Likov, In the group, our revision revealed a new species, Vujić, Radenković & Likov, , and the revalidation of Gil Collado, 1929, Macquart, 1842 is redescribed.

The Extraordinary Diversity of Complex (Diptera: Syrphidae)-Adding New Areas, New Species and a New Molecular Marker.

In this paper, the (Diptera, Syrphidae) species complex was revised, whereupon we discovered and described four new species for science: Vujić, Radenković et Likov sp. nov., Vujić, Kočiš Tubić et Ačanski sp.

The Genus Heterogynis Rambur, 1866 (Heterogynidae, Lepidoptera): Congruence of Molecular, Morphological and Morphometric Evidence Reveal New Species in Serbia.

The Heterogynidae are a small family of moths consisting of a single genus and sixteen described species distributed in the Mediterranean region. A species new to science, sp. nov.

Characterization of preimaginal developmental stages of two cryptic South African species of the Merodon planifacies complex (Diptera: Syrphidae: Eristalinae: Merodontini), with differentiation through morphometry analysis.

Merodon capi Vujić et Radenković, 2020 and Merodon roni Radenković et Vujić, 2020 are two cryptic species belonging to the Merodon planifacies Bezzi, 1915 species complex that have recently been described, with the differences between them being revealed by molecular and geometric morphometry studies of adult specimens. In the present study, the preimaginal morphology of both species is described and displayed, with the material used corresponding to samples taken from bulbs of Merwilla plumbea (Lindl.) Speta plants at two locations in KwaZulu-Natal province (South Africa).

Review of the Merodon albifasciatus Macquart species complex (Diptera: Syrphidae): the nomenclatural type located and its provenance discussed.

The Palaearctic Merodon geniculatus species group (Diptera, Syrphidae: Merodontini) currently comprises six Western Mediterranean species and four species with Eastern Mediterranean distribution. One of this group species, Merodon albifasciatus Macquart, 1842, is the only Merodon species listed from the Oriental Region. We discovered the lost holotype, which fit morphologically with European Merodon females of the M.

Molecular and Morphological Inference of Three Cryptic Species within the Merodon aureus Species Group (Diptera: Syrphidae).

The Merodon aureus species group (Diptera: Syrphidae: Eristalinae) comprises a number of different sub-groups and species complexes. In this study we focus on resolving the taxonomic status of the entity previously identified as M. cinereus B, here identified as M.

Phylogeographic patterns of Merodon hoverflies in the Eastern Mediterranean region: revealing connections and barriers.

We investigated the phylogeographic patterns of Merodon species (Diptera, Syrphidae) in the Eastern Mediterranean. Ten species were sampled on five different islands and mainland sites as a minimum. All samples were screened for their mtDNA COI barcode haplotype diversity, and for some samples, we additionally generated genomic fingerprints.

Revision of the species of the Merodon nanus group (Diptera: Syrphidae) including three new species.

The nanus group of the genus Merodon Meigen (Diptera, Syrphidae) is revised, yielding an illustrated key, a discussion of taxonomic characters and morphological diagnosis for the five species of this group. Three new cryptic species are described, Merodon kopensis Vujić et Hayat sp. n.
