The name is used here as 'the pale one' in reference to the light coloured fore and hind feet and tail tip, as well as the dorsal pelage which is paler than in most other species of Microgale. Comparisons with other species. Microgale fotsifotsy differs from other species of Microgale in a number of external and craniodental features. The combination of light body coloration and conspicuously pale coloured feet and tail tip, and the large, pale ears are unique to this species (see Figs 1 and 2). The early stages of the eruption sequence apparently differs from that ascribed toM. cowani andM. pusilla Major, 1896b by MacPhee (1987) and toM. soricoides Jenkins, 1993. In the sequence common to the three latter species, 13 and i3 erupt in the first stage, followed in sequence by P2, p2, p4, and 11 and i 1 at the end of the second stage. In the specimens available of M. fotsifotsy, the sequence progresses from i3 to 13, to II to il, to p2 then P2, so that, unusually the first upper and lower permanent incisors replace the deciduous teeth before any of the permanent premolars have erupted.
