Specimens examined. Kenya: 1 female, Sondu, Nyanza Province, on Ficus sycomorus , 3-XII-1989, J.S. Yaninek. South Africa: Holotype female, Limpopo Province, Mlambane, Kruger National Park, on F. sycomorus , 4-X-1953, M.K.P. Smith Meyer; 4 females, Mpumalanga Province, 15 km from Swaziland border to Amanxale, on F. sycomorus , 5-II-1985, E.A. Ueckermann. 1 male, Kwazulu/ Natal Province, Pongola River near Golela, on F. sycomorus , 19-VIII-1980, E.A. Ueckermann.

Remarks. The single specimen collected from Kenya has JV5 slightly serrate and macrosetae only on genu and tarsus of leg IV; specimens from South Africa have JV5 smooth, and have in addition to the macrosetae on genu and tibia of leg IV, a knobbed seta (slightly shorter than the macroseta) on each of those segments.

World distribution. Kenya, Lesotho and South Africa.
