Venter ( Fig. 9 View FIGURE 9 E)—Ventrianal shield subtriangular, with transverse striae anteriorly to Jv2; 120 long, 148 wide at the anterior corners, 4 pairs of lyrifissures (2 anterior to Jv1, 1 lateral and posterior to Jv1 and 1 lateral and posterior to Zv2); preanal pores elliptical, posterior and almost on line behind Jv2.

Spermatodactyl—L-shaped; shaft 17 long.

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 Z4 ca. 1.2 times as long as s4, Z4 ca. 75%, Z5 ca. 30%, s4 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.
