Canis lupus hattai—an extinct species from the Japanese island of Hokkaido
Canis lupus hodophilax—an extinct species from the other Japanese islands
Canis lupus lupus—the common wolf of Europe and forested Russia
Canis lupus pallipes—a small wolf from India and the Middle East
Other authorities might have added Canis lupus arabs, a small, light-colored wolf from southern Arabia, which Sokolov and Rossolimo regarded as a synonym of pallipes; Canis lupus lupaster, in Egypt, which many authorities regard as a subspecies of Canis aureus, the golden jackal; and Canis lupus communis, from the Ural Mountains of Russia and Siberia.
Nowak suggested combining campestris, chanco, and desertorum with lupus. His analysis would also recognize pallipes, cubanensis, albus, communis, and hattai. He did not analyze arabs, lupaster, or hodophilax.
