Remarks — Measurements of the specimens collected fit well those given in the original description of the species. Moraes et al. (2001) reported a wide variation in setal lengths of specimens identified as E. nyalensis from sub-Saharan Africa. The calyx of the spermatheca of the specimens collected is very similar to the illustration of Moraes et al. (2001).

Specimens collected — 2 females, on Urena lobata , at University Cheikh Anta Diop, in August 2006; 2 females on Anacardium occidentalis L., 5 females and 1 male on Ficus sycomorus L., at KBD, in February 2009.

World distribution — This species has been reported from Asia, northern and sub-Saharan Africa.
