DNA barcoding and morphology reveal European and western Asian Arctiavillica (Linnaeus, 1758) as a complex of species (Lepidoptera, Erebidae, Arctiinae).

Currently, the genus Arctia Schrank, 1802 includes approximately 16 species in the Palaearctic region, depending on the taxonomic interpretation. Here, populations of the Arctiavillica (Linnaeus, 1758) morphospecies complex were studied from Europe to the Middle East (Turkey, northern Iran) by molecular methods. Morphological treatment has traditionally revealed the presence of five nominal taxa: A.villica (Linnaeus, 1758), A.angelica (Boisduval, 1829), A.konewkaii (Freyer, 1831), A.marchandi de Freina, 1983, and A.confluens Romanoff, 1884. The molecular approach tests whether they represent well-delimited species. Subsequently, this study corroborates the suitability of the mitochondrial cytochrome c oxidase subunit 1 (COI) marker sequence for species delimitation. In total, 55 barcodes of the Arctiavillica complex were compared, and two molecular species delimitation algorithms were applied to reveal the potential Molecular Operational Taxonomic Units (MOTUs), namely the distance-based Barcode Index Number (BIN) System, and the hierarchical clustering algorithm based on a pairwise genetic distances approach using the Assemble Species by Automatic Partitioning (ASAP). The applied ASAP distance-based species delimitation method for the analysed dataset revealed an interspecific threshold of 2.0-3.5% K2P distance as suitable for species identification purposes of the Iberian A.angelica and the Sicilian A.konewkaii and less than 2% for the three taxa of the A.villica clade: A.villica, A.confluens, and A.marchandi. This study contributes to a better understanding of the taxonomy of the genus Arctia and challenges future revision of this genus in Turkey, the Caucasus, Transcaucasia as well as northern Iran using standard molecular markers.

Local abundance patterns of noctuid moths in olive orchards: life-history traits, distribution type and habitat interactions.

Local species abundance is related to range size, habitat characteristics, distribution type, body size, and life-history variables. In general, habitat generalists and polyphagous species are more abundant in broad geographical areas. Underlying this, local abundance may be explained from the interactions between life-history traits, chorological pattern, and the local habitat characteristics. The relationship within taxa between life-history traits, distribution area, habitat characteristics, and local abundance of the noctuid moth (Lepidoptera: Noctuidae) assemblage in an olive orchard, one of the most important agro-ecosystems in the Mediterranean basin, was analyzed. A total of 66 species were detected over three years of year-round weekly samplings using the light-trap method. The life-history traits examined and the distribution type were found to be related to the habitat-species association, but none of the biological strategies defined from the association to the different habitats were linked with abundance. In contrast to general patterns, dispersal ability and number of generations per year explained differences in abundance. The relationships were positive, with opportunistic taxa that have high mobility and several generations being locally more abundant. In addition, when the effect of migrant species was removed, the distribution type explained abundance differences, with Mediterranean taxa (whose baricenter is closer to the studied area) being more abundant.

Bryophila perloides Guenée, 1852 (Lepidoptera: Noctuidae: Bryophilinae), an overlooked member of the European Noctuidae fauna, with upgrading of Bryopsis Boursin, 1970 to generic level (Taxonomic studies on the western Palaearctic Bryophilinae, No. 1).

The generic level segregation of the formerly unified taxa Nyctobrya Boursin, 1957 and Bryopsis Boursin, 1970 is discussed; the second one is reinstated as a genus, on the basis of apomorphic features in the male genitalia (Bryopsis stat. rev.). The large genus Bryophila Treitschke, 1825 is briefly characterized, in order to assess the specific identity of the formerly misinterpreted Bryophila perloides Guenée, 1852, the only European member of its species-group. So far as is known, B. perloides (stat. rev.) inhabits the southernmost, pericoastal area of Andalusia (Spain), and is known to date from five specimens. It is, thus, to be included in the Iberian and European checklists of Noctuidae. All other described species of the perloides species-group are North African. They are reviewed and their types checked; the adults, as well as their genitalia, are illustrated. Genitalia of all holotypes/syntypes are studied. Also, lectotypes are designated for B. perloides, B. squamosa Schwingenschuss, 1936 and B. barbaria Schawerda, 1934.
