Type material. Lectotype (present study).

Material examined. Lectotype, adult female ( NHM 1924.5.30.20), Cap Blanc, Mauritania, Africa, coll. Dr. Th. Monod, May 30, 1920. MNHN–Ta96212 (2 slides).

Diagnosis (adult female and male). Rostrum rounded. Pleotelson tapering posteriorly to rounded tip with the posterior margin with row of simple setae and lacking two long terminal plumose setae. Antennule first peduncle article lacking ventral spiniform setae; accessory flagellum of two articles. Male cheliped fixed finger cutting edge with large rounded tooth. Cheliped and pereopod 1 exopodite with three plumose setae. Pereopod 1 propodus with nine–10 ventral spiniform setae. Pereopods 2 and 3 propodus with very stout pectinate spiniform seta subdistally on inner surface; dactylus with digitiform lobe bearing more than five aesthetascs. Pereopod 5 propodus with short terminal bipinnate setae. Pereopod 6 propodus with several long simple setae on outer surface. Female pereopod 6 dactylus with several subterminal setae. Uropod basal article approximately 2.7 times as long as broad, with several simple setae on the outer margin and short spiniform seta on the inner distal corner.

Type Locality. Mauritania, NW Africa, Eastern Atlantic , littoral (Fig. 1, number 19) .

Geographic distribution. Known from type locality only.

Remarks. Unfortunately the type material that is mounted on slides is in very bad condition. The following features could be distinguished: 1) inner flagellum of antennule with 2 articles, 2) first peduncle article of antennule densely setose, 3) pereopod 1 exopodite with three plumose setae, and 4) pereopod 1 propodus with nine–10 ventral spiniform setae. All that was left of the cotype (= syntype) to examine was the body (carapace missing), one pereopod 3, one pereopod 5, and one pereopod 6 ( Fig. 52 ). Unfortunately Monod (1923) did not illustrate pereonites 5–6 or pereopods 4–5 but the cotype we examined is very similar to his original description (i.e, 10 ventral spiniform setae on pereopod 1 propodus, etc.). The cotype was designated as the lectotype.
