Remarks. Length of most of the dorsal setae, of the macroseta on tarsus IV and of the calyx of the spermatheca of the specimens examined varied greatly within and between countries. The specimens from Sierra- Leone are smaller than those from other countries; the smallest specimen from that country, collected in Moyamba, Gbangbama, has in general the shortest dorsal setae.

World distribution. Benin, Cameroon, Democratic Republic of Congo, Ghana, Nigeria and Sierra- Leone.
