PULVERIS (DIPTERA: SYRPHIDAE): DELIMITATING CRYPTIC HOVERFLY SPECIES USING THE GEOMETRIC MORPHOMETRIC METHOD 2019-09-03T13:29:44+02:00 Maja Arok Jelena Ačanski Tamara Tot Snežana Radenković Ante Vujić <p>A landmark-based geometric morphometric method was employed to delimitate two morphologically closely-related species of the hoverfly <em>Merodon natans</em> species group based on wing parameters. The studied species, <em>Merodon natans</em> and <em>M. pulveris</em>, were successfully determined using this method. Analyses revealed a significant difference in wing size and shape between individuals of the two species, thereby proving that these are two distinct species, even though, morphologically very similar. Discriminant and cluster analyses also uncovered a subtle difference in wing shape between <em>M. pulveris</em> populations, indicating intraspecific differentiation with potential conservation implications. The results of the morphological study were supplemented with known distribution data of the investigated species.</p> 2019-09-03T13:28:45+02:00 ##submission.copyrightStatement##
