Mag. Nat. Hist., ser. 7, 19: 381 . Type Locality: NE Dem. Rep. Congo , Orientale , Angu, Uele River. Vernacular Names: Eastern Rainforest Grammomys . Synonyms: Grammomys centralis (Dollman 1914) . Distribution: Probably most of the E Congo Basin in S Central African Republic , Dem. Rep. Congo , forest patches in W Uganda ( Delany, 1975 , as rutilans ), and possibly Republic of Congo ; limits unresolved. Discussion: Phylogenetically closely related to G. poensis but differs in its smaller skull and shorter molar rows. The karyotype 2n = 50 described by Matthey (1963) for a specimen captured in Republic of Congo probably refers to G. kuru and contrasts with the 2n = 36 reported from the Côte d’Ivoire (see account of G. poensis ). The taxon kuru has been treated as a synonym of G. rutilans (D. H. S. Davis, 1965; Musser and Carleton, 1993 ) or sometimes listed as a species (e.g., Ellerman, 1941 ), but with provisions ( Hatt, 1940 b ; Hutterer and Dieterlen, 1984 ; Thomas, 1915 ); our study of the holotype revealed it is a very young adult. Measurements of the molar rows are like those in samples from E Dem. Rep. Congo and unlike samples of the larger G. poensis (see discussion in Hatt, 1940 b ).
