Sody’s Yellow Bat is similar to the Lesser Asiatic Yellow Bat (S. kuhlii ). Western form has smaller average skull characteristics than eastern form, but external measurements are generally larger. Dorsal pelage is dark brown; venter is paler straw yellow. Bare skin is olive-brown. Muzzle is broad and blunt, with swollen glands on both sides and simple nostrils.
