27 spp. are at present known from the Durmitor range. 23 of these are here recorded from a sphagnum peat bog, 2 lakes and 2 streams (alt. 750-1495 m), and commented upon in terms of the “Representative Spectrum of Odonata Species” (RSO) of E. SCHMIDT (1985, Odonatologica 14: 127-133). The bulk (44.5%) of the Durmitor fauna consists of 12 Euro-Siberian spp. that are common, or moderately common in the sites examined.
