Description

Mastomys sp.

REMARKS

There is a high morphological variability in the old collections from Nimba. However, most of the non-typed specimens fit well with M. natalensis as shown on the DFA on skull measurements (Fig. 10). The specimens found within houses in Ziela, Foromota and Glabouyouma villages are generally young individuals and look smaller than specimens found in open sites and probably fit with M. natalensis which is more commensal in forested zones of Guinea than M. erythroleucus (Denys et al. 2009; Lalis et al. 2012). Coe (1975) collected eight specimens he attributed to M. erythroleucus at 500 m altitude, seven were found in cassava and rice farms and one in secondary forest. Gautun et al. (1986) collected two specimens attributed to M. erythroleucus on Zougepo plateau. Misonne & Verschuren (1976) listed 18 specimens attributed to M. cf. erythroleucus from Gbapa, Yekepa and Nimba base in cultivated fields, secondary bushes and savannas, and abandoned villages.
