Таксономический статус комплекса видов, относящихся к длиннопалому раку, до настоящего времени является предметом дискуссий. Вид характеризуется широкой морфологической изменчивостью, однако специальных работ по оценке этой изменчивости относительно немного. В данном исследовании на основе многомерного канонического дискриминантного анализа проведено сравнение 7 популяций раков из водоемов бассейнов Черного и Балтийского морей Западного Полесья. С помощью морфометрического анализа популяций выявлены отличия между ними, особенно по таким параметрам, как абдомен и карапакс. Полученные результаты свидетельствуют о необходимости проведения молекулярно-генетического изучения длиннопалого рака в Беларуси и сопредельных стран.

Taxonomical status of the narrow-clawed crayfish species complex is remained as unclear and it is still the subject of discussion. Despite many ambiguities, uniform data related to morphological diversity are scare. Therefore, the main aim was to compare populations from the same type of waterbody and different drainage (Baltic and Black Sea) from the Polesye region with multivariate statistics in order to morphological diversity verification. The result indicates that variability of studied populations is expressed especially in abdomen and cephalothorax parameters which is comparable to other works on morphometry of the European freshwater crayfish species. Some studies showed differences on morphology have been also confirmed at the genetic level. The information obtained in this study indicates that genetic analyses are necessary for understanding the diversity of this species.
