10. Striped Dwarf Hamster Cricetulus barabensis French: Hamster de Chine / German: Daurischer Zwerghamster / Spanish: Hamster enano rayado Taxonomy. Mus barabensis Pallas, 1773, Kasmalinskii Bor, banks of Ob River, W Siberia, Russia. Cricetulus barabensis is in the barabensis species group. In the past, there was confusion about taxonomy of griseus and pseudogriseus, which were eitherlisted as species on their own right or subspecies of barabensis. Both griseus (2n = 22) and pseudogriseus (2n = 24) differ in karyotypes from barabensis (2n = 20), but all chromosomal forms intebreed successfully. Up to six subspecies have been recognized, but actual number is not established with certainty. Subspecific differentiation needs to be clarified pending further studies. Treated here as monotypic. Distribution. NE Kazakhstan, Russia (W Siberia from Irtysh River E through Transbaikalia to Ussuri region in Russian Far East), Mongolia, N, NE & C China, and extreme NW & NE Korean Peninsula. Descriptive notes. Head-body 72-124 mm, tail 15-33 mm, ear 14-18 mm, hindfoot 13-19 mm; weight 20-60 g. Dorsal pelage of the Striped Dwarf Hamster is light graybrown to reddish, with mid-dorsalstripe that is prominent or obscured. Ventral pelage is gray, and hairs have gray bases and white tips. Ears are blackish and white framed. Tail is ¢.30% of head-body length;it is dark above and lighter below. Skull has proportionally long rostrum and nasal bones and moderately large braincase. Interoribial region is broad and without supraorbital ridges. Snout is short. Auditory bullae are large. Molars are low-crowned, with cusps arranged in two parallel series. Chromosomal complement has 2n = 20-24 and FN = 38. Habitat. Arid areas such as steppe, forest steppe, and semi-deserts; frequently found in river valleys, close to other water sources, in croplands, and sometimes in houses. Food and Feeding. The Striped Dwarf Hamster eats grains, legumes, leaves, and insects. Food is transported in pouches that can carry 3—4 g (exceptionally up to ...
