MATERIAL EXAMINED. — MNHN : 2011-916, 2011-918, 2011-920, 2011-921, SPOT 10143. ZFMK : 69.207 , 69.206 . Morphological characters The species name rutilans used by Eisentraut (1968) for some specimens of Mt Oku is no longer valid and has been replaced by poensis ( Musser & Carleton 2005 ) . We collected five new specimens fitting well with the holotype of G. poensis described by Eisentraut (1965) from Bioko ( Table 8 ). The adult females examined (n = 3) all possessed a mammary formula of 0 + 2. Grammonys poensis is present all over the CVL mountains of Cameroon from Mt Oku to Mt Cameroon , as well as in Bioko ( Eisentraut 1973 ), Mt Kupe ( Denys et al. 2009 ) and Mamfé ( Sanderson 1940 ).
