Measurements of 2 adult females collected are: dorsal shield 300 – 304 long and 163 – 170 wide; j1 35 – 38, j3 83 – 85, j4 and j5 3 – 5, j6 5 – 6, J5 3 – 5, z2 8 – 10, z4 8 – 10, z5 3 – 5, Z1 7 – 9, Z4 73 – 75, Z5 95 – 100, s4 118 – 125, r3 43 – 45, R1 30 – 32; distances between st1 – st3 68 – 70, st2 – st2 68 – 69 and st5 – st5 85 – 88; ventrianal shield 113 – 115 long, 68 – 70 wide at level of ZV2, 65 wide at anus level; Sge II 13 – 15, Sge IV 28 – 30, Sti IV 32 – 38, St (basitarsus) IV 43 – 45, St (telotarsus) 33 – 35.

Chaetotaxy — genu II 2, 2/0-2/0, 1; genu III 1, 2/1-2/0, 1.

Remarks — Measurements of the specimens collected are similar to those given by Moraes et al. (2007) for specimens from sub-Saharan Africa, including the holotype. The presence of a macroseta on genu II and not on genu III, observed in the specimens collected and in the specimens examined by Moraes et al. (2007) is not common for other phytoseiid mites. Usually, the presence of a macroseta on a given leg implies its presence on subsequent legs.

Specimens collected — 28 females and 9 males on Centaurea perrotettii DC. , Chrosophora senegalensis Vis. and Urena lobata L, at KBD, in November 2009.

World distribution — This species has been reported almost only from sub-Saharan Africa; the exception refers to a single report from India ( Gupta, 1981).
