dc.description.abstractChromosomal inversions are important drivers of genome evolution. The Eurasian malaria vector <i>Anopheles</i> <i>messeae</i> has five polymorphic inversions. A cryptic species, <i>An. daciae</i>, has been discriminated from <i>An. messeae</i> based on five fixed nucleotide substitutions in the internal transcribed spacer 2 (ITS2) of ribosomal DNA. However, the inversion polymorphism in <i>An. daciae</i> and the genome divergence between these species remain unexplored. In this study, we sequenced the ITS2 region and analyzed the inversion frequencies of 289 <i>Anopheles</i> larvae specimens collected from three locations in the Moscow region. Five individual genomes for each of the two species were sequenced. We determined that <i>An. messeae</i> and <i>An. daciae</i> differ from each other by the frequency of polymorphic inversions. Inversion X1 was fixed in <i>An. messeae</i> but polymorphic in <i>An. daciae</i> populations. The genome sequence comparison demonstrated genome-wide divergence between the species, especially pronounced on the inversion-rich X chromosome (mean Fst = 0.331). The frequency of polymorphic autosomal inversions was higher in <i>An. messeae</i> than in <i>An. daciae.</i> We conclude that the X chromosome inversions play an important role in the genomic differentiation between the species. Our study determined that <i>An. messeae</i> and <i>An. daciae</i> are closely related species with incomplete reproductive isolation.en
