Chestnut sac-winged bat : ウィキペディア英語版 | Chestnut sac-winged bat
The chestnut sac-winged bat, or Wagner's sac-winged bat (''Cormura brevirostris'') is a species of sac-winged bat native to South and Central America. It is the only species within its genus. ==Description== The chestnut sac-winged bat is a relatively small member of its family, with adults measuring in length, and weighing . Soft dense fur covers the body, and the inner parts of the wings, reaching as far as the mid-humerus and mid-femur on both the upper and lower surfaces. The fur is brown-black or red-brown in colour, being darker above, and paler on the underside of the animal. The wings are black, with the membranes extending as far as the ankles. The tail projects from the middle of the membrane between the legs, but does not extend beyond it, and so is not visible in silhouette. The tail measures about in length, although only of the tip is visible above the membrane. Males of the species have sacs in the centre of the membranes on the forward surfaces of the arms, which reach from the edge of the membrane almost to the elbow. This distinguishes it from all other sac-winged bats, in which the sac is usually much closer to the body.〔
