dc.description.abstractAphidius colemani kompleks vrsta je definisan kao grupa vrsta sa pantropsko-suptropskim rasprostranjenjem koja se odlikuje malim brojem brazdi, karakterističnog položaja, na anterolateralnom regionu petiolusa. Predstavlja jednu od 10 grupa vrsta (kompleksa) sa nerešenim taksonomskim statusom u okviru roda Aphidius. Morfološka i genetička karakterizacija Aphidius colemani kompleksa izvršena je primenom morfometrije i analize sekvenci barkoding regiona gena za subjedinicu jedan citohrom oksidaze (COI). Morfometrijskim analizama obuhvaćeno je 250 jedinki A. colemani kompleksa sа prostorа 23 države sa četiri kontinenta. Analizom varijabilnosti morfoloških karaktera pokazano je postojanje značajnih razlika u pogledu njihove informativnosti u pogledu razdavjanja različitih grupa ovog kompleksa. UtvrĎeno je koji su morfološki karakteri dovoljno informativni za razlikovanje taksona unutar ovog kompleksa parazitskih osa. Molekularne analize su obuhvatile 54 jedinke iz 8 država. Analizom sekvenci COI gena i rekonstrukcijom filogenetskih odnosa utvrĎeno je postojanje skrivenog taksona unutar A. colemani kompleksa. Kombinacijom rmorfometrijskih i molekularnih metoda utvrĎeno je da u okviru Aphidius colemani kompleksa vrsta postoje najmanje tri taksona: Aphidius colemani, Aphidius transcaspicus i Aphidius cf. colemani 1 (novi takson). UtvrĎeno je da novotkirvena vrsta naseljava Aziju (Iran) i Južnu Ameriku (Čile). Pokazano je da ne postoji jasna veza izmeĎu genetičke diferencijacije parazitoida ovog kompleksa i njihovih afidnih domaćina, kao ni izmeĎu genetičke diferencijacije i geografskog porekla.sr
dc.description.abstractAphidius colemani species complex has been defined as a group of species with pantropical – subtropical distribution which is characterized by low number of grooves (costulae) with specific position on the anterolateral region of the petiole. This group is one of the 10 groups of species (complexes) with unsolved taxonomical status among the genus Aphidius. Morphological and genetic characterization of the Aphidius colemani complex was done by using morphometrics and DNA sequence analysis of the barcoding gene for Cytochrome oxidase I (COI). In total 250 specimens of A. colemani complex from 23 deferent countries on four continents were encompassed with morphometric analysis. By analyzing variability of morphological characters, statistically significant differences were noted in the sense of their informativity in separation of deferent groups of the complex. Molecular analysis was performed on 54 specimens from eight deferent countries. By analyzing sequences of COI gene and the reconstruction of phylogenetic relations, one hidden taxon was detected among the A. colemani complex. Combination morphometric and molecular methods has shown the existence of at least three distinct taxa: Aphidius colemani, Aphidius transcaspicus and Aphidius cf. colemani 1 (new taxon). This new species can be found in Asia (Iran) and South America (Chile). It has been shown that there are no clear connections between genetic differentiation of the parasitoids from this complex and their aphid hosts, as well as between genetic differentiation and geographic distribution.en
