Description

A bat found in Teine, Sapporo, Hokkaido (43°07′N, 141°11′E) on 9 November 2007 was identified as Hypsugo alaschanicus (Bobrinskii, 1926) from morphological data. This is the fourth capture in Sapporo, and the eighth in Japan. The skull of this specimen was compared with those of other five specimens of H. alaschanicus previously recorded in Japan. The occasional absence of anterior upper premolars, which was previously pointed out, was confirmed. In comparison with Eptesicus nilssonii, the direction of the upper canine cusp and the ratio of the height of the lower canine to that of the posterior premolar were newly found useful as additional morphological characters to identify both species.<br>
