| description | Background. The systematic position of the earthworm Dendrodrilus rubidus (Bimastos rubidus) has
been changed many times due to differences in its anatomy and external morphology, which were revealed in
individuals that at first glance belonged to the same species. Deviations from existing diagnoses also made taxonomic
determination difficult. The research goal is to conduct comparative morphometric and molecular genetic
analyses of D. rubidus (B. rubidus) individuals from different regions of Russia and Belarus to identify accurate diagnostic
features. Materials and methods. For the study, we collected four samples of adult individuals of D. rubidus
(B. rubidus), depending on geographical location. The worms were collected in the territories of Russia (European
part, Western Siberia, North-Western Caucasus) and Belarus. Morphometric analysis was carried out
according to the main qualitative and quantitative anatomical and morphological features. The variability of the
mitochondrial cytochrome oxidase I (cox 1) gene used in molecular taxonomy was evaluated using molecular-genetic
analysis. Further the data obtained from the two analyses were compared. Results and conclusions. Previously, it was
believed that only two subspecies of D. rubidus (tenuis and subrubicundus) were present in the studied territories,
which are currently considered to be species forms. During the study, we found three forms of this species: tenuis,
rubidus and subrubicundus. The revealed anatomical and morphological differences make it possible to determine
the species forms of adult individuals of D. rubidus, taking into account possible deviations from generally accepted
diagnoses. There were no significant molecular-genetic differences between the different species forms. |
