Graphiurus lorraineus Dollman, 1910

Graphiurus lorraineus Dollman, 1910: 285 .

REMARKS

In the MNHN we found five specimens attributed to G. spurelli murinus that fit well with our new specimens from the Guinean and Liberian sides of the mount. In the NMK collection specimens attributed to Graphiurus sp. (NMK 514, 515, 561) were attributed to G. lorraineus by one of us (AM). This small glirid is uniformly grey-brown and displays a relatively long and hairy tail. Its hindfeet are small. The tail color matches the dorsal pelage and reaches 72 to 80% of HB length in the newly collected specimens but this character appears highly variable. The belly is grey-white. There is no facial mask and no post-auricular patchs. The hindfoot is white. The external standard measurements are given in Table 11 and fit within the species variability. The skull is small with a poorly marked CIO, a short and broad rostrum and a relatively square braincase. The nasal is not straight and it curves downwards onto the side of the snout. There is no fronto-parietal crest. In ventral view the incisive foramina are short. The molars are small and the palate ends just after M3/. The tympanic bullae are elongated with traces of septae and are inflated in their middle. The incisors are orange and orthodont. The mandible is low. Skull measurements are provided in Table 12 and fit well with the old Lamotte collection values for Nimba, Seredou and Côte d’Ivoire. Like all Graphiurinae there are four small cheek teeth with laminated lophs and squarish morphology with no further diagnostic features and they are not figured here.
