Note the large Ml with biserial cusps and a lon- gitudinal valley, separating the labial t3, t6, t9 from the lingual "tO", t2, t5, and t8. A "14" is lingually attached to t5; the cusp pattern on M2 is still visible but heavily worn; M3 very small, as typical for the genus. Habitat. In Ethiopia the species is "nearly always asso- ciated with long grass and bushes" (Yalden et al. 1976; Rupp 1980). NE Congo, Garamba NP: dry savannah, but found there in moist habitats around swamps etc. (Ver- ~ HEYEN & Verschuren 1966). Congo (Kivu Highland): moist savannah, but only in relative diy grassy habitat mixed with bush vegetation, possibly due to competition with two other species of Dendromus (Dieterlen 1971). N Kivu: «biotope caractéristique, végétation élevée, broussailleuse, que Ton trouve sur les bords des marais nombreux qui occupent les fonds de toutes les vallées» (Misonne 1963). E Africa: "D. has adapted to cultivation quite readily ..." (Kingdon 1974). South- ern Africa: grassland associated with rank vegetation, es- pecially stands of high coarse grasses such as Hyparrhe- nia sp. at 1-2 m height (De Graaf (1981; Skinner & Smithers 1990). Nest. "This is the species to which the only positive tree- dwelling records are attached, but the habitats of the dif- ferent forms and apparently of the same form in different locations, are variable" (Rosevear 1969, on D. mysta- calis). For East Africa Kingdon (1974) noted, ".. it
