Description of Dryocosmus destefanii new species (Hymenoptera: Cynipidae: Cynipini) from Quercus suber L. in Italy
2018
A new species, Dryocosmus destefanii Cerasa & Melika n. sp. associated with a Cerris section oak, Quercus suber L., is described from Italy. Description, diagnosis, host associations and biology for the new species and an illustrated identification key to the Western Palaearctic Dryocosmus species are given. The description is supported by morphological and molecular data.

Revision of the genusXyalaspisHartig, 1843 (Hymenoptera: Figitidae: Anacharitinae) in the Western Palaearctic
2015
ABSTRACT A revision of Xyalaspis Hartig, 1843 (Hymenoptera: Anacharitinae) in the Western Palaearctic region is given. Xyalaspis spinigera Reinhard, 1860 and Xyalaspis subulifera (Thomson, 1862) are synonymized with Xyalaspis laevigata Hartig, 1843 and Xyalaspis rugosa Hartig, 1843 respectively, and their distribution areas are extended. A new species Xyalaspis pseudolaevigata n. sp. is described from France. One species previously assigned to the genus Xyalaspis, X. laevis (Hedicke, 1914), is transferred to Aegilips Haliday, 1835. Diagnostic characters are illustrated and data about biology, distribution and morphological variability of the studied species are presented and discussed. A ke…

2014
The first comprehensive revision of the Western Palaearctic species of the genus Dinotrema Foerster, 1862 is provided. 174 species of this genus are redescribed and illustrated.

Parapatric diversification after post-glacial range expansion in the gall flyUrophora cardui(Tephritidae)
2010
Aim Primary and secondary genetic clines in post-glacial colonized regions have different implications for biogeographic distributions and the origin of species. Primary clines arise in situ after colonization as adaptive responses to environmental gradients, while secondary clines are caused by contact between vicariant lineages. Here we analyse primary versus secondary origin of a genetic cline in the tephritid fly Urophora cardui in Jutland, Denmark, in a post-glacial landscape. Location Western Palaearctic. Methods Phylogeographic and demographic analyses of U. cardui based on mitochondrial DNA (mtDNA) genealogies, hierarchical genetic variance tests based on allozymes and distributi…
