Abstract / Introduction / Summary:
We examined the distribution and morphological variation of the Eothenomys smithii population in Kagoshima Prefecture. Females had longer average total length, head-body length, tail length, hind foot length, and ear length than males. In the skull measurements, the CBL, LUD, LUM, ZW, MDL, and LLM were longer in females than in males. Lengths of tails and hind feet were long at lower latitudes in the Kyushu district. Skull sizes and molar row lengths from Inaodake and Hoyoshidake were larger than those from Shibisan and Takakumayama in both sexes. These results were supported by principal component analysis of 14 skull characters. Each group of the four captured areas at an altitude of more than 850 m may be an isolated population.
