Abstract [eng] Partial sequences of COI and EF-1α of nine aphid species of the family Adelgidae and partial sequences of 16S rRNA of their endosymbiotic bacteria were used to reveal co-evolutionary relationships between endosymbiotic bacteria and their aphid hosts in Lithuania. In addition to currently recognized taxa of gamma- and beta-proteobacterial endosymbionts (“Candidatus Vallotia”, “Candidatus Profftia”, “Candidatus Annandia”, “Candidatus Hartigia”, “Candidatus Ecksteinia”, “Candidatus Steffania” and “Candidatus Gillettellia”) of Adelgidae, new gamma-proteobacterial (Sodalis-allied) endosymbionts were detected in Adelges (Aphrastasia) pectinatae and Pineus cembrae. Cophylogenetic analyses based on aphid partial COI and EF-1α sequences and 16S rRNA gene fragment of their endosymbiotic bacteriae showed reliable cophylogenetic events confirming the importance of host aphid species relatedness in structuring symbiont communities of adelgid aphid species. Molecular aphid species delimitation analyses based on Bayesian phylogenies of aphid COI and EF-1α and bacterial 16S rRNA fragments indicate adelgid species complexes Adelges (Adelges) laricis - Adelges (Adelges) tardus, Adelges (Gilleteella) cooleyi - Adelges (Gilleteella) coweni, Adelges (Dreyfusia) nordmannianae - Adelges (Dreyfusia) piceae, Adelges (Sacchiphantes) abietis - Adelges (Sacchiphantes) viridis and Pineus pini - Pineus orientalis representing single species each.
