The samples from Pčinja and Trebinje possessed divergent haplotypes that corresponded to east (HI) and west (HV) genetic clusters, respectively. Geometric morphometrics was found to be a suitable method to distinguish divergent genetic clusters, arguing for the reassessment of a subspecific ranking within the currently recognized eastern Hermann’s subspecies, <em>T. h. boettgeri.</em></p><p><a href="https://doi.org/10.2298/ABS190604043D">https://doi.org/10.2298/ABS190604043D</a></p><p><strong>Received:</strong> June 4, 2019; <strong>Revised:</strong> July 5, 2019; <strong>Accepted:</strong> July 15, 2019; <strong>Published online:</strong> July 25, 2019</p><p><strong>How to cite this article:</strong> Đurakić MR, Milankov VR.
