A new species of Meligethes (Coleoptera: Nitidulidae: Meligethinae) of the M. lugubris complex from Sardinia*

چکیده
A combined morphological and bionomical analysis was performed to clarify the position of a problematic species of the Meligethes lugubris group from Sardinia and Corsica (Coleoptera, Nitidulidae, Meligethinae). This species-group is represented by a dozen anthophagous species associated with Lamiaceae, and distributed from North Africa to Japan. The analysis was mainly focused on the specific distinction and formal description of a new species, M. foddaii Audisio, De Biase & Trizzino sp. nov., from Sardinia and Corsica. The species is morphologically scarcely distinguishable from the allopatric M. lugubris Sturm and M. gagathinus Erichson (both widespread in southern Europe). An identification key to Euro-Mediterranean members of the M. lugubris complex is provided. Combined morphological, ecological, phenological, and preliminary molecular data are presented to support the distinction of the new species. The palaeogeographical scenario explaining the likely Plio-Pleistocene differentiation of the three species, which are all associated with the related Lamiaceae genera Mentha and Thymus, is also briefly discussed.

The pollen-beetle Jelinekigethes dichromus n. sp. from northern South Africa is described. The new species is closely related to the other known species of this genus, J. danielssoni (Audisio 1995) from southwestern South Africa. The taxonomic position of Jelinekigethes is discussed in the context of presumably related African and Oriental meligethine genera. Larval host plants of both species ...
متن کاملMolecular taxonomic analysis of the plant associations of adult pollen beetles (Nitidulidae: Meligethinae), and the population structure of Brassicogethes aeneus.
Pollen beetles (Nitidulidae: Meligethinae) are among the most abundant flower-visiting insects in Europe. While some species damage millions of hectares of crops annually, the biology of many species is little known. We assessed the utility of a 797 base pair fragment of the cytochrome oxidase 1 gene to resolve molecular operational taxonomic units (MOTUs) in 750 adult pollen beetles sampled fr...
