Mus (Nannomys) callewaerti Thomas 1925

Mus (Nannomys) callewaerti Thomas 1925 , Ann. Mag. Nat. Hist., ser. 9, 15: 668.

Type Locality: S Dem. Rep. Congo, Kasaï-Occidental, Kananga (= Luluabourg), 610 m.

Vernacular Names: Callewaert's Mouse.

Distribution: Recorded only from NE and C Angola ( Crawford-Cabral, 1998), S and W Dem. Rep. Congo; limits unknown.

Conservation: IUCN – Lower Risk (lc).

Discussion: Subgenus Nannomys . Thomas described this species as a member of the genus Hylenomys , which is now united with Mus ( Hill and Carter, 1941; Misonne, 1965 a) as a synonym of Nannomys . It is the largest-bodied of any of the African Mus (F. Petter and Matthey, 1975) , has ivory incisors and very large auditory bullae, and in external features resembles M. triton , which misled Hatt (1940 a) into treating callewaerti as a subspecies of triton . Misonne (1965 a) summarized distributional and other information.
