Genetic diversity of Philaenus spumarius and P. tesselatus (Hemiptera, Aphrophoridae): implications for evolution and taxonomy
The meadow spittlebugs Philaenus spumarius and P. tesselatus are closely related taxa with uncertain taxonomic position in the light of previous morphological, ecological, cytological and molecular research and it is possible that additional taxa exist.
Molecular phylogeny of the Mediterranean species of Philaenus (Hemiptera: Auchenorrhyncha: Aphrophoridae) using mitochondrial and nuclear DNA sequences
The phylogenies of all eight European species of Philaenus were estimated from cytochrome oxidase subunit I, cytochrome B and internal transcribed spacer 2 (ITS2) fragments of DNA using phylogenetic
Cytotaxonomy and karyology of the tribe Otiorhynchini (Coleoptera: Curculionidae)
The karyological findings support the taxonomical revision of Otiorhynchini based on mor- phological characters.
C-bands on chromosomes of 32 beetle species (Coleoptera: Elateridae, Cantharidae, Oedemeridae, Cerambycidae, Anthicidae, Chrysomelidae, Attelabidae and Curculionidae).
C-banding patterns of 32 beetle species from the families Elateridae, Cantharidae, Oedemeridae, Cerambycidae, Anthicidae, Chrysomelidae, Attelabidae and Curculionidae confirmed that most of the beetle species possess a small amount of heterochromatin and C-positive segments are weakly visible in pachytene stages and weakly or imperceptible in mitotic and meiotic metaphases.
Occurrence of Wolbachia in central European weevils: correlations with host systematics, ecology, and biology
The results suggest horizontal transmission of Wolbachia strains between species and recombination events between different strains, which might have been influenced by common ancestry among the studied weevils.
Cytogenetic differences between Peritelus familiaris and Centricnemus leucogrammus (Coleoptera: Curculionidae: Entiminae: Peritelini)
Results indicate the usefulness of cytoge- netic methods in taxonomic evaluations and show significant differences in karyotype structure of Centricnemus leucogrammus and Peritelus familiaris.
New data on the cytology of parthenogenetic weevils (Coleoptera, Curculionidae)
The C-banding method showed that only two species possess a large amount of heterochromatin visible as a band around the centromere during mitotic metaphase, which supports the hypothesis that the evolution of apomictic parthenogenesis in weevils has proceeded through a stage of automixis.
Mediterranean Species of the Spittlebug Genus Philaenus: Modes of Chromosome Evolution
The most plausible scenario of chromosomal rearrangements accompanying phylogenetic differentiation in Philaenus is advanced and the first reported case of an evolutionarily fixed multiple sex chromosome system in Auchenorrhyncha is reported.
Karyotype analysis of three weevil species from the Genera Brachysomus (Boheman, 1845) and Strophosoma Billberg, 1820 (Coleoptera, Curculionidae).
The karyotype structures of the two bisexual and one parthenogenetic species are described for the first time and Geographic parthenogenesis in Brachysomus hirtus is briefly discussed.
