Specimens examined. Ghana: 10 km E Obuasi, Ashanti Region, on unknown plant, 10-XI-1989, J.S. Yaninek; 1 km W River Pora, Beposo, Central Region, on unknown plant, 12-XI-1989, J.S. Yaninek; Atimpoku, Adomi Bridge, Eastern Region, on unknown plant, 13-XI-1989, G.J. de Moraes; 23 km N Otumi, Chromolaena odorata , 28-III-1990, J. Gyemenah. Kenya: 27.9 km S Mombasa, Coastal Province on Zea mays , 28- XI-1989; J.S. Yaninek; 17 km N Lunga Lunga, Coastal Province on Physalis angula , 28-XI-1989, J.S. Yaninek. Mozambique: 5.5 km SE Mitili, Zambezia Province, on Tridax procumbens , 25-IV-01, B. Agboton. Sierra-Leone: Njala University, on Lantana camara , 12-XII-1991, J.S. Yaninek. USA: Holotype female from Winter Haven, Florida, on Canna sp .. South Africa: Tzaneen, Limpopo Province, from Vernonia stipulacea , 19-II-1965, M.K.P. Smith Meyer (holotype and paratype of P. peltatus ); Machadodorp, Mpumalanga Province, from Pennisetum clandestinum , 17-I-1977, E.A. Ueckermann; Zimbabwe: Triangle, from Cynodon dactylon , 03-XI-1969, M.K.P. Smith Meyer.

Remarks. Proprioseiopsis peltatus was synonymized with P. ovatus by Tseng (1983). The measurements of specimens from South Africa and other sub-Saharan African countries examined in this study are intermediate to those given by Moraes & McMurtry (1983) for the holotypes of Proprioseiopsis cannaensis ( Muma, 1962) and P. ovatus . The spermathecae of the specimens considered in this study also seem intermediate to those shown by Moraes & McMurtry (1983) for the holotypes of those species. It seems that P. ovatus could also be a senior synonym of P. cannaensis as admitted by Muma & Denmark (1969).

World distribution. Brazil, Costa Rica, Cuba, Ecuador, Egypt, Ghana, Hawaii, Honduras, Kenya, Philippines, Puerto Rico, Sierra Leone, South Africa, Taiwan, USA and Zimbabwe.
