Abstract

Porodica vodenih kornjaša Elmidae je općenito jako slabo istražena. Kod vrsta Elmis aenea (Müller, 1806) i E. rioloides (Kuwert, 1890) sakupljenih na rijeci Cetini uočene su morfološke razlike u građi pronotuma i muškog spolnog aparata kako unutar populacija tako i u odnosu na jedinke istih vrsta u središnjem dijelu Europe. Glavni cilj ovog istraživanja je analizirati može li se uočena morfološka razlika potvrditi i na razini mtDNA. Filogenetske analize ukazale su na odvajanje jedinki vrste E. rioloides s rijeke Cetina od tipičnih predstavnika srednjoeuropske faune podupirući dosadašnju pretpostavku da je vrsta E. rioloides kompleks vrsta. Na molekularnoj razini nisu pronađene značajne genetičke razlike između populacija analiziranih vrsta s obzirom na promatrane morfološke značajke i/ili lokalitet na rijeci Cetini. Do razdvajanja između grupa vrste E. rioloides iz Srednje Europe i s područja Cetine došlo je u geološkom razdoblju pleistocena što je u skladu s pretpostavkom o važnosti pleistocenskih refugija u specijacijskim procesima na području Balkana.

Abstract (english)

Water beetles of the familiy Elmidae (Coleoptera) are generally very poorly studied. Elmis aenea (Müller, 1806) and E. rioloides (Kuwert, 1890) species wich were collected from the Cetina River showed morphological differences in the structure of the pronotum and the male reproductive system both within the population and in relation to individuals of the same species in Central Europe. The main aim of this study was to analyze whether the observed morphological differences can be confirmed at the level of mtDNA. Phylogenetic analysis indicated the separation of specimens of E. rioloides from the Cetina River from typical representatives of Central European fauna, supporting the hypothesis that E. rioloides is a complex species. No significant genetic differences between populations of analyzed species with respect to the observed morphological features and / or location on the Cetina River were observed. Separation between the groups of E. rioloides from Central Europe and the Cetina River occurred in the Pleistocene which is consistent with the observation of the importance of Pleistocene refugia in speciation processes in the Balkans.
