چکیده

Calomyscidae is a monotypic family of muroid rodents with nine valid allopatric species distributed in southwestern Asia of which seven species have been so far recognized from Iran. The only species which was reported from the Zagros Mountains in western and southern Iran was Calomyscus bailwardi but recent studies have revealed in addition to C. bailwardi, four other divergent lineages occur in the Zagros Mountains. One of them was recently described as a new species (C. behzadi) but the taxonomic position of the other lineages remains unclear. Here we did extensive sampling in southern Iran (2017-2018), during which 99 Calomyscus specimens were collected. Based on an intergated approach using karyotypic, molecular as well morphological data, we describe Calomyscus kermanensis sp. nov. as a new endemic species from southern Iran including Kohgiluyeh and Boyer-Ahmad, Fars, Kerman, Yazd and Hormozgan provinces. The new species constituted a new lineage in a phylogenetic tree with high intraspecific genetic divergence. Three different karyotypes were found for this new lineage. The multivariate and univariate statistical analyses of craniodental measurements also separated C. kermanensis sp. nov. from other examined Calomyscus species with the highest maximum cranial height being the most distinctive of its cranio-mandibular features. This new taxon is introduced from regions previously known as the distribution area of C. bailwardi.
