TYPE LOCALITY: " Cameroon River, West Africa" [ Cameroon ] . DISTRIBUTION: Cameroon , Congo , Equatorial Guinea , Gabon , Kenya , Niger , Tanzania , Zaire . SYNONYMS: microdon Allen, 1919 . COMMENTS: Placed in Xenogale by Allen (1919b), and followed by Rosevear (1974) and Ansell (1978) . This taxon, and ichneumon , which is generally recognized as its sister taxon ( Allen, 1919b ; Rosevear, 1974 ; Hayman, in Sanderson, 1940 ), can be distinguished principally by proportional differences of the interorbital region ( Rosevear, 1974 ). Hayman (in Sanderson, 1940 ), Wenzel and Haltenorth (1972) , and Coetzee (1977b) did not feel these differences were sufficient to warrant generic distinction, as did Allen (1919b) , and Rosevear (1974) . Recognition of Xenogale would make Herpestes paraphyletic.
