Remarks. Specimens belong to Iphinoe africana constituted about 30 % of the collected material. The differentiation from the very similar species Iphinoe brevipes Hansen, 1895 and Iphinoe stebbingi Jones, 1956 was discussed in this africana – brevipes – stebbingi group (Jones, 1956, Day 1978; Mühlenhardt-Siegel, 1996). We observed considerable variations in our individuals associated with growth and sexual dimorphism for several features. Concretely, the lengths of the different articles of pereopod 1 and pereopod 2 and numbers of teeth on telsonic somite. The ratio of carapace length to carapace height ranged from 2.25 to 2.75, the basis of pereopod 1 could be longer than the rest of the limb and the basis of pereopod 2 could be nearly as long as broad (Fig. 17). According to Day (1978) the distribution of I. brevipes is limited from North to 5°S and I. stebbingi is found in South Africa.
Distribution. South West Africa from Angola to Cape Point (South Africa), 0–130 m
