abstract

Variability of 36 cranial characters of Spalax microphthalmus was analyzed on the sample of its Eastern Ukrainian population. Selection of characters was carried out on the basis of analysis of all set of morphological peculiarities, which are considered as diagnostic characters of this species from all other species of Spalacidae, known in the fauna of Eastern Europe (5 species of Spalax and 1 species of Nannospalax). On the basis of character variation analysis, further attention was concentrated on 9 ones, that can by described as qualitative characters, that differ S. microphthalmus from all other Eastern European Spalax. For each species of Spalax, main morphotypes were established and portion of their appearance in S. microphthalmus was estimated. It was shown, that in the analyzed sample of this species there are 10 morphotypes of 6 characters, that are characteristic for other species of Spalax. The largest number of coincidences in characters, that are commonly considered as diagnostic for S. microphthalmus, was established in comparisons with group Spalax arenarius + S. giganteus.
