The population diversity of the Euro-Siberian species Meromyza nigriseta Fedoseeva, 1960 was analysed using morphometric and molecular genetic data obtained (CO1 mtDNA locus) based on 12 populations from the central part of its geographical range. The colour variations of the mid mesonotal stripes were insufficient for identification of inter-population diversity. The size of the anterior processes of postgonites (AP) and the unique sequence of the CO1 mtDNA gene can serve as markers of the population diversity. Seven haplotypes with genetic distance from 0.1 to 0.3% were identified. We recorded H1 haplotype in samples from all regions, except Tula (T), Brest (B) and Kaliningrad (Kl) populations. The load-graph in the plane of the principal components revealed a strong influence of the total (St) and main (Smap) part of AP. The Moscow (M) and Ural (Ur) populations of M. nigriseta differed most substantially from T and Kl populations by the projecting part of the area of AP (Spap), Smap and St. In addition, St of AP increased from Ur to the western population and Smap from U to Kl ones. Meromyza nigriseta originated in the grasslands and steppe ecosystems of Eastern Europe and then during the period from 44,000 to 130,000 years invaded new regions. [ABSTRACT FROM AUTHOR] |
