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

Remarks — Measurements of the specimens collected are similar to those reported by Ueckermann et al. (2007) for specimens from sub-Saharan Africa, including the holotype; the length of the macroseta of basitarsus IV of the specimens collected is close to the lower extreme of the range given by those authors. The length of the calyx of the spermatheca is similar to that of the holotype and to the average given by Ueckermann et al (2007) for other specimens.

Specimens collected — More than 220 specimens, on Centaurea perrottetii DC. , Chrosophora senegalensis Vis. , Urena lobata L. and Waltheria indica L., at KBD, between 2005 and 2010; 25 females, on U. lobata and W. indica , at Malika, between 2006 and 2009.

World distribution — This species has been reported almost only from sub- Saharan Africa; the exception refers to a single report from the Island of La RØunion, in the Indian Ocean ( Quilici et al., 2000).
