Fig. 2 E, F

West African records. Amphioholis bananensis : Koehler 1911: 14; Longhurst 1958: 100; Tommasi 1967: 534; Madsen 1970: 205. Amphiopholis clypeata: Koehler 1914: 19 ; A. M. Clark 1955: 38; Longhurst 1958: 100.

Material examined. St. BE17: grab sampling, 17°18.946´S, 11°43.389´E; 15 specimens, 2–5 mm. Depth: 26 m. This species only occurred at this station.

Diagnosis. The oral papillae are arranged in a continuous series with the distal one being at least twice as broad as the other ones. A few specimens bear an extra oral papilla in some jaw angles, distally to the broad papilla at the adoral plate. Oral shields are distinctly longer than broad. Disc scales are fine and primary plates are evident. There are two scales at each tentacle pore.

Distribution. Northern West Africa: Ivory Coast and southwards, southern West Africa: Angola (17°S, previously known only as far south as 8°S) and northwards, at littoral depths.
