Other common names: Caspian Shrew
Taxonomy. Crocidura russula caspica Thomas, 1907 View in CoL ,
Iran, “ South coast of Caspian Sea [Iran]. Ad. - 25 m.”
Evidence retrieved from the karyotype composition, mtDNA and nDNA sequences classify C. caspica in the C. suaveolens group. It was previously thought to be a subspecies of C. gueldenstaedtii , but studies of mtDNA and nDNA structures showed that C. caspica is far closer to C. suaveolens . Monotypic.
Distribution. Lankaran Lowland and Talysh Mts (SE Azerbaijan and NW Iran). View Figure
Descriptive notes. Head-body 67-83 mm,tail 40-51 mm; weight 9-8-14 g (immatures 7-3-9-5 g; pregnant females may weigh up to 17-5 g). The Caspian White-toothed Shrew is large and heavily built. Tail is relatively long, usually exceeding 60% of head-body length. Pelage is virtually unicolor: the back varies from brown to dark brown, the belly is somewhat lighter. Tail is unicolor, the same color as the back. Chromosomal complement is 2n = 40, FN = 50, with four pairs of metaand submetacentric autosomes, 15 pairs of acrocentric autosomes. X-chromosomeis large metacentric, Y-small acrocentric.

The Caspian White-toothed Shrew inhabits mountain slopes covered with humid forest, where oak ( Quercus , Fagaceae ), alder ( Alnus , Betulaceae ), iron tree ( Parrotia persica, Hamamelidaceae ), maple ( Acer , Sapindaceae ), and linden ( Tilia , Malvaceae ) prevail.
