- Аннотация: We have studied variability of 31 cranial characters in three morphological species of lesser (midteranean) mole rats (Rodentia, Spalacidae, Nannospalax Palmer, 1903: N. ehrenbergi, N. nehringi, N. leucodon). The results of nonparametric multivariate morphometric analyses (multidimensional scaling, cluster analyses) correspond with the taxonomic system by Topachevskii (1969). The significant morphological difference between N. ehrenbergi and pair «N. nehringi - N. leucodon», and also between N. nehringi and N. leucodon is confirmed. N. ehrenbergi is close to N. nehringi than to N. leucodon in the multidimensional morphological space. Geographical variability is discovered at N. nehringi and N. leucodon. These geographical forms correspond the subspecies (N. l. leucodon, N. l. monticola, N. n. nehringi, N. n. cilicicus) described before. The highest differences have been found in: maximal and basal length of skull, length of palate and facial part, mastoid width, zygomatic width, rostrum width, width of base of skull between fossae glenoidea, length of tooth rows and some others. The sexual dimorphism in N. leucodon and N. ehrenbergi is weakly marked, but in N. n. nehringi it is discovered in practically all parts of the skull. Differences in such dimorphism are found between geographical forms. Pattern of variability in genera Nannospalax is not stable. There are quick decrease of number of varying measures, decrease both Shannon’s entropy and dimensionality of morphological space from the top to the low hierarchical levels («exhausting of morphological diversity»).
