Taxonomy

This species is extremely variable and many forms, especially from Crimea, were treated as separate species before a revision using methods of molecular taxonomy was carried out.^[3]

Distribution

This species occurs in southern and eastern Ukraine and in the adjacent regions of Russia. Most numerous and diverse populations are in the Crimean Mountains. All reports of H. filimargo outside those regions were referring to various other species of Geomitridae.^[3]
