MALE. Not encountered in this study.
Specimens examined. Burundi: Murongwe, on unknown plant, 25-V-1990, J.S. Yaninek. Kenya: 13 km W Kwale, Coastal Province, on Terminalia catappa (Combretaceae), 29-XI- 1989, J.S. Yaninek; 13 km N Sigya, Nyanza Province, on unknown plant, 2-XII-1989, J.S. Yaninek. Mozambique: Mitilili, Zambezia Province, on Cajanus cajan (Fabaceae), 25-IV-2001, B. Agboton. Rwanda: ISAR Station, Rubosa, Butare, on Solanum sp. (Solanaceae), 6-XII-1989, J.S. Yaninek. Hong Kong: (paratype) on Urena lobata (Malvaceae), 23-VIII-1960, E. Swirski.
Remarks. There is a controversy in relation to the status of several species of Paraphytoseius (Chant & McMurtry, 2003b). Denmark et al. (1999) and Matthysse & Denmark (1981) considered P. horrifer to be a junior synonym of P. orientalis (= multidentatus), but Chant & McMurtry (2003b) preferred to consider them different species until the respective type specimens are compared side by side. Our examination of the holotype of P. horrifer and of a paratype of P. multidentatus at different times indicates that the major differences between them are that the former has longer (ca. 20%) Z4, Z5 and s4, and lacks: a distinctly short, thick, spatulate seta on genu I; macrosetae on leg III; and a short, thick, blunt or knobbed seta on both genu and tibia IV. The specimens of P. horrifer collected in the present study have a short blunt seta on basitarsus IV and sometimes on femur IV (both apparently absent in the holotype of P. horrifer).
