Tullberg's Praomys

discussion

REMARKS The holotype was described in 1892 under the name Mus burtoni by Thomas from Ankober [= Ankobra] River, Wasa, Ashantee, Gold Coast region and in 1894 was renamed to Mus tullbergi because the name burtoni was preoccupied by another species (Thomas 1892, 1894). Heim de Balsac & Lamotte (1958) described two morphs of Praomys that they attributed to P. jacksoni and P. morio. A large form with a long hindfoot that could fit with P. rostratus and a smaller one that could represent P. tullbergi. Coe (1975) recorded 94 specimens attributed to P. tullbergi and Misonne & Verschuren (1976) also recovered more than 100 specimens from the Liberian side of Mount Nimba indicating that they represent a single homogeneous series and named them as P. tullbergi. Gautun et al. (1986) indicated that both species coexist on the Guinean side of Mount Nimba. The Cyt b barcoding has allowed us to attribute old collection specimens to P. tullbergi which confirms previous works. P. tullbergi is very similar in external morphology to P. rostratus in having also a rufous-brown dorsal pelage, a white belly and a tail length longer than HB one (mean: 121,8 %; range: 105 - 136 %) (Table 7).

Discussion: Reviewed by Rosevear (1969), Van der Straeten and Verheyen (1981), and more recent reports cited in the above species accounts. Morphologically closely related to P. misonnei, P. morio, and P. rostratus. Grubb et al. (1998) reviewed populations in the Gambia, Sierra Leone, and Ghana. Ecological information recorded for population on Accra Plains of S Ghana by Decher and Bahian (1999). A karyotype of 2 n = 34 (all acrocentric autosomes) was recorded by Granjon et al. (1992) from Senegal, which is similar to karyotypes obtained from samples collected in Côte d’Ivoire and Central African Republic (Matthey, 1958). Additional comments on Senegal distribution given by Duplantier and Granjon (1992). Barnett et al. (1996) documented its occurrence on the Kounounkan Massif in SW Guinea. See account of P. rostratus.
