Remarks. Viets (1916) assigned specimens from Cameroon to E. spinifer (Koenike,
1893), a species described initially based on the female sex only. However, Encentridophorus females show few species-specific characters, and therefore I agree with Bader (1981) that the assignment of Viets (1916) is questionable. Bader (1981) described his specimens from Cameroon as E. vietsi Bader, 1981 , and postulated that the specimens of Viets might belong to this species. My male from the Gambia has the posterior idiosoma margin with 4+1 (in the holotype 5+1) pairs of stout setae, but is otherwise similar to E. vietsi . In my opinion the male from the Gambia and the specimens from Viets (1916) belong all to E. vietsi . The number of stout setae at the posterior idiosoma margin is, therefore, 4–6 pairs of setae + a separated seta on each side. Bader (1981) was the opinion that the specimens reported by Walter 1939) from Chad do not belong to E. vietsi , but belong possibly to a new species. Bader based this opinion on the measurements of leg segments and the number of swimming setae. I disagree with Bader, and I don′t see any marked differences between the specimens from Chad and Cameroon. Distribution. West Africa, previously reported from Cameroon ( Viets 1916 ; Bader 1981),
Chad ( Walter 1939), the Gambia, Ghana (this study).
