Abstract
Glossina spp. were collected in south-western Ethiopia and were found to have a continuous distribution from the Sobat River Basin to the southern Rift Valley lakes of Chamo and Abaya. Their limits to the north and east of this range was not determined. Along the Omo River, Glossina inhabit a continuous band from 20 km above Lake Rudolf to at least as far as Abelti, 167 km south-west of Addis Ababa. The species collected were G. pallidipes Aust., G. fuscipes Newst., G. morsitans submorsitans Newst. and G. Iongipennis Corti. The ratio and numbers of G. pallidipes and G. fuscipes suggest a relationship between the latter and the number of hippopotamus along the Omo River. Both G. pallidipes and G. Iongipennis were caught biting at night.
