Yaninek; 27.9 km S Mombasa, Coastal Province, on Citrus sp., and on unknown plant, 28-XI-1989, J.S. Yaninek. Two females, Malawi: 11 km W Nkhata-Bay, Northern Province, on Mangifera indica, 18-V-2001, I.D. Zannou. Two females, Mozambique: Movia, Nacala-Velha, Nampula, on Anacardium occidentale, 4-V-2002, I.D. Zannou. Three females, Rwanda: 5 km N Ruhengeri, on Markhamia lutea, 8-XII -1989, J.S.

REMARKS—Most of the specimens collected are larger than the holotype of A. sundi; concurrently, they also have setae Z4, s4 and leg macrosetae distinctly longer; the largest differences refer to macrosetae of leg IV, which are, on average, ca. 40% longer. An analysis of the holotypes of A. sundi, Amblyseius parasundi Blommers, 1974 and Amblyseius solus Denmark & Matthysse, in Matthysse & Denmark (1981), showed that they are very similar, suggesting that those species could be synonyms. The first of those species was described from Democratic Republic of Congo and has been reported from several other countries in the African continent, as well as in Cape Verde and Madagascar. The second was described from Madagascar and has never been reported from other countries. The third was described from Nigeria and has never been reported later in the literature. According to Blommers (1974), A. parasundi differs from A. sundi by its shorter Z5 and shorter macrosetae on leg IV, and by being thelytokous. The holotype of A. sundi has j3, Z5, s4 and macrosetae of leg IV ca. 20% longer as well as macrosetae of leg III at least 30% longer than the holotype of A. solus. However, given the variation of the measurements of the specimens collected in this study, we feel that those differences could represent intra-specific variation, and thus, A. solus is not included in the key provided later in this paper.
The specimens from Burundi, Ghana, Ivory Coast, Malawi, Sierra Leone and Uganda are smaller than the others examined in this study, whereas those from Kenya, Malawi and Rwanda have the longest setae Z4, Z5 and s4.
WORLD DISTRIBUTION—Benin, Burundi, Cameroon, Cape Verde, Congo, Democratic Republic of Congo, Ghana, Ivory-Coast, Kenya, Madagascar, Malawi, Mozambique, Nigeria, Rwanda, Sierra Leon, Uganda and Zimbabwe.
