New species from the family hydroptilidae in croatian fauna collected in the krka national park with particular notice to biodiversity and dna barcoding

Abstract

In this study we present: two species of caddisflies new for Croatian fauna from the family Hydroptilidae (Hydroptila simulans Mosley, Orthotrichia costalis Curtis), first DNA barcoding of caddisfly species in the Krka National Park and a discussion about recorded caddisfly fauna in the Krka NP from this study. From a faunistic point of view several species are interesting: Hydropsysche mostarensis Klapálek, Hydroptila simulans Mosely, Hydroptila forfcipata Eaton, Orthotrichia costalis Curtis and Tinodes pallidulus McLachlan. For the species Oecetis notata Rambur we have recorded interesting taxonomical remarks. Furthermore, within this study we used DNA barcoding which showed to be a very good and useful method for identification of very small and morphologically similar species from the family Hydroptilidae, or females from the family Psychomyiidae.
