Fig. 10: Distribution of two lamina types of Tatera valida. D = First lamina open posteriorly U = First lamina open anteriorly zania and Zambia. Verheyen & Verschuren (1966) who studied T. valida in the Garamba National Park, Zaire considered it to be a rodent typical of upland grassland savanna, while Delany (1975), in his work on the rodents of Uganda wrote that it favoured "'savanna particularly grassland' and that it "penetrated forests along the edges of tracks". T. valida is known to prefer well drained sandy soils, for according to Vesey-FitzGerald (1966) it is common in the sandy alluvium along rivers and in old gardens and woodlands where the soil had been loosened by cultivation. It is also known to colonise fallow land where the original forest and woodland have been cleared, (Kingdon, 1974). In Ethiopia, it was found in the Didessa and Abbai riverine valleys that extend into the Ethiopian plateau. According to Morris, Largen & Yalden (1975) T. valida was present in these valleys along with other typical savan- na taxa, such as Mus, Thryonomys and Lemniscomys striatus. Tatera valida, although known to feed on insects, including ants and orthopterans (Delany 1964) is primarily a grass eater during the rains whilst at other times it feeds on the underground parts of grasses and sedges (Vesey-FitzGerald, 1966). It lives in small groups in elaborately constructed burrow systems containing several tunnels, a terminal chamber and a nest. The system may have depth of up to 62 cm and cover an area approximately 2.7 x 1.4 m, (Delany, 1964). Females have three to four foetuses. Delany noted that in Uganda they were found to breed from May to July and September to December and that the testes were about 20 mm long at matura- tion..
