Craniometric analysis of mouse-like hamsters of the genus Calomyscus (Critecidae)

摘要

The multivariate discriminant analysis of data on size-corrected cranial measurements in 195 specimens of the genus Calomyscus from Turkmenia, northern Iran and Azerbaidjan suggests grouping of 29 samples into five clusters. Three of these clusters correspond to the chromosome forms previously described from Turkmenia. The other two are C. urartensis from Azerbaidjan an C. bailwardi grandis from the central Elburz mountains. Specimens from Chorassan (presumably C. elburzensis) appear to be similar to Calomyscus sp. with 2n = 44 occuring in the eastern and central Kopetdag. Discriminant functions for the forms recognized in Turkmenia are given.
