Legs—Sharp-tipped macrosetae: Sge I 36, Sge II 33, Sge III 41, Sti III 36, Sge IV 86, Sti IV 73 and St IV 64.

SPECIMENS EXAMINED—One female, Benin: Cotonou, Départment du Littoral, on Terminalia catappa  , 3 -XI- 1989, G.J. Moraes. Two females and 1 male, Ghana: University of Cape Coast, Cape Coast, Central Region, on Mangifera indica  , 12 -XI- 1989, J.S. Yaninek. Four females, Kenya: 6.5 km S Likoni, Coastal Province, on unknown plant, 22 -XI- 1989, C.W. Kariuki; 6.5 km S Mombasa, Costal Province, on Cocos nucifera  , 28 -XI- 1989, J.S. Yaninek; 50 km S Mombasa, Costal Province, on Plumeria rubra  , 28 -XI- 1989, J.S. Yaninek. Two females, Sierra Leone: Lansar, on Luffa aegyptiaca  , 16 -XII- 1991, J.S. Yaninek.

REMARKS— Amblyseius neolargoensis  Van Der Merwe, 1965 is very similar to A. largoensis  , but it differs by having Z 4 ca. 1.2 times as long as s 4, Z 4 ca. 75 %, Z 5 ca. 30 %, s 4 ca. 45 %, Sge IV ca. 45 %, Sti IV ca. 25 % and St IV ca. 25 % longer than in A. largoensis  .

Phytoseiid taxonomists do not agree on the synonymy of those two species. Chant et al. (1978) and Muma et al. (1970) reported that A. largoensis  is a senior synonym of A. neolargoensis  , while Amitai & Swirski (1981), McMurtry & Moraes (1984) and Schicha (1981) reported that they are two different species. Based on the differences mentioned above we also considered them as different species in this study.
