The species Dina lineata (Müller, 1774) inhabits freshwater habitats of western Palearctic
from Great Britain to Iran. Predaceous leeches from the suborder Erpobdelliformes show a
degree of morphological variability which leads to description of several subspecies. Boris
Sket described three subspecies of D. lineata on the Balkan Peninsula (D. l. dinarica, D. l.
lacustris, D. l. montana) and suspected presence of nominotypical subspecies D. lineata
lineata, which was confirmed by recent studies. On the Balkan Peninsula, predominantly on
the Dinaric Alps, several new species in the genus Dina were recently described (D.
minuoculata, D. prokletiaka, D. sketi). These species show preference to same habitats as
Balkan subspecies of D. lineata and relatively small morphological differences.
Phylogenetical relations between subspecies of D. lineata are not clear. Contemporary
molecular- genetic analyses enable clarification of these relations. The aim of this study is to
determine the phylogenetic and phylogeographic relations between subspecies of D. lineata
as well as their relations with other species in the genus Dina. The study incorporates large
area from the Sava River in the northwest to Macedonia in the southeast. Three subspecies of
D. lineata were recorded during the field work. D. l. dinarica was the most frequent, D. l.
lineata was recorded on few localities in Serbia and D. l. montana was collected on the
Komovi mountain (Montenegro). Analyses of phylogenetic relations were conducted on the
sequences of mitochondrial DNA that code for cytochrome oxydase I (COI). The results show
that D. l. dinarica could be treated as separate species D. dinarica. This taxon shows
significant phylogeographical variability. Analyses have shown grouping of haplotypes based
on geographical origin of populations. Haplotypes from Serbia were grouped in one group,
those from Bosnia and Herzegovina in to second and third group was comprised of haplotypes
from Montenegro. Great genetic variability may indicate potential hidden speciation within D.
dinarica species.
