Dalton's Praomys

discussion

Discussion: Reviewed by Rosevear (1969) and Van der Straeten and Verheyen (1978 b). Although its geographic range allopatrically complements the distribution of Myomyscus brockmani, P. daltoni is not conspecific with that E African species, a conclusion based on our study of specimens and analyses of morphological (Lecompte et al., 2001 a) and molecular (Lecompte et al., 2002 b) data. DNA / DNA hybridization results clustered daltoni with species of Praomys (Chevret et al., 1994) as did phylogenetic analyses of morphometric traits (Van der Straeten, 1979), complete mtDNA cytochrome b sequences (Lecompte et al., 2002 b), and nuclear IRBP gene data (E. Lecompte, in litt., 2002); however, partial 16 S rRNA mitochondrial sequences pointed to daltoni as sister group to species of Stenocephalemys. Van der Straeten (in litt., 1994) regarded derooi and daltoni to be closely related to Praomys tullbergi. Chromosomal morphology documented for samples from Côte d’Ivoire (Matthey, 1964), Senegal (Granjon et al., 1992), and NE Mali (Dobigny et al., 2001 a, b; Volobouev et al., 2002 b); 2 n = 36, FNa = 34 for all samples. The taxon tuareg was described as a subspecies of Grammomys macmillani, bu

COMMENT: Subgenus Myomyscus; see Misonne, 1974, Part 6: 27. Includes Myomys ingoldbyi; see Van der Straeten and Verheyen, 1978, Z. Saugetierk., 45: 31 - 41, who placed daltoni in subgenus Myomys. May include butleri (EVS).
