<p>U radu je izvršen integrativno-taksonomski pristup analize kompleksa vrsta <em>Merodon</em> <em>avidus </em>(Diptera: Syrphidae), na geografski i vemenski obimnom materijalu. U okviru genetičke karakterizacije kriptičnih vrsta navedenog kompleksa, bazirane na 3' i 5'<br />fragmentima mitohondrijalnog COI gena, određeni su parametri genetičke varijabilnosti i utvrđeni jedinstveni i deljeni haplotipovi u okviru i između pretpostavljenih vrsta. Rezultati genetičke varijabilnosti COI DNK sekvenci pokazali su da jedinke sa ostrva Krf i Evia i poluostrva Peloponez, preliminarno identifikovane kao M. moenium, predstavljaju novu, endemsku vrstu proučavanog<br />kompleksa. Dijagnostički enzimski lokusi pokazali su da M. avidus i M. moenium predstavljaju sestrinske vrste, koje su se, u okviru kompleksa vrsta <em> M. avidus, </em>poslednje razdvojile. Zaključeno je da se kompleks vrsta M. avidus sastoji od 5 vrsta: <em>M. avidus, M. moenium, M. megavidus, M. ibericus i M. aff. moenium</em>. U nastavku, oslanjajući se na moderne tehnike veštačke inteligencije, izvršeno je modelovanje distribucije vrsta i poređenje sličnosti utvrđenih ekoloških niša. U poslednjem segmentu istraživanja, prednosti veštačke inteligencije iskorišćene su u modelovanju sistema za determinaciju jedinki sestrinskih vrsta u uzorku, na osnovu adekvatne varijable.Ovo istraživanje doprinelo je karakterizaciji biodiverziteta osolikih muva, rasvetljavanju taksonomskog statusa vrsta i kreiranju smernica za definisanje budućih konzervacionih programa zaštite biodiverziteta vrsta <em>Merodon avidus </em>kompleksa.</p> / <p>During this research, an integrative-taxonomic analysis of M. avidus species complex was performed. The study was based on geographically and temporally extensive material. Genetic characterisation of cryptic species, based on 5’ and 3’ regions of COI gene, defined parameters of genetic variability. Shared and unique haplotypes between and within of cryptic species were detected. The results of genetic variability analysis based on COI gene showed that specimens from the islands Corfu, Evia and half-island Peloponnese, which were preliminarily identified as M. moenium, represent a new, endemic species of the selected complex. Diagnostic enzyme loci showed that M. avidus and M. moenium represent sibling species, which were the last one who separated within M. avidus complex. According to current information, it was concluded that M. avidus complex consists of 5 species: M. avidus, M. moenium, M. megavidus, M. ibericus and M. aff. moenium. In the next chapter, relying on modern techniques of artificial intelligence, the species distribution modelling and the comparison of ecological niches were performed. In the last part of the research, the advantages of artificial intelligence were used in order to model a system that was able to determinate one of two sibling species, based on appropriate predictor. This research has generally contributed to a characterization of hoverfly diversity and helped resolving a taxonomic status of species in one of the most challenging groups in Syrphidae family. Genetic differentiation data represent directions for defining future conservation strategies for biodiversity protection of defined cryptic species of Merodon avidus complex</p>
