Eocuma lanata LeLoeuff & Intes, 1972: 27 , fig. 4

Material examined. 1 male, 5.5 mm; 1 ovigerous female, 4.6 mm; 1 female 9.6 mm (St. 1: dredge sampling; 7°14.090´S, 12°41.010´E)

Remarks. A single record of this species was used for description of one adult female and one preadult male (both 7 mm in total length) (LeLoeuff & Intes, 1972). This species is very similar to E. ferox and E. dimorphum in having one pair of lateral horns. However, the basis of pereopod 1 of E. lanatum is slightly shorter than carpus and propodus together, whereas it is about 1.5 times longer in both other species. Contrary to the hairless body of E. ferox and E. dimorphum , the carapace of E. lanatum is covered with a napped coat (LeLoeuff & Intes, 1972). Our material comprises one ovigerous female and one adult male about 5.5 mm in length which match the original description in most parts. The adult individuals are much smaller, but the paired horns, the serration of the exopod of uropod and the aspect ratio of articles of pereopod 1 attribute the individuals to that species. Our material contains a third individual, a female of 9.6 mm length. The carapace carries a very strong pair of lateral horns, nearly reaching the tip of the pseudorostrum ( Fig. 16 ). The serration of the exopod of uropod is weakly formed. The carpus of pereopod 1 is equal in length to merus, the propodus is 1.5 times longer than carpus and the dactylus one third of the propodus ( Fig. 16 ).

Distribution. West Africa Ivory Coast, Angola; 41– 250 m.
