A 16-month field study of the nocturnal prosimianGalago crassicaudatus umbrosus in the Northern Transvaal, South Africa, revealed extensive homerange overlaps between adults of both sexes, age-graded male tolerance, and a high rate of direct affiliative contact between individuals of most age-sex classes. These results contrast with the general characterization of nocturnal lorisid sociality given by Charles-Dominique (1978). Nocturnal prosimians’ dispersion while foraging supports the predation model of group cohesion in diurnal primates. The problem of group size and cohesion should be divorced from that of social networks and social complexity. There may be benefits to social interactions which transcend group living. The more subtle differences in nocturnal prosimian sociality need to be reconsidered in the light of current sociobiological and socioecological theory.
