MEASUREMENTS—Our specimens have carapace widths of 20 and 22 mm.
BIOLOGY.—Globopilumnus africanus is a shallow water species, generally found intertidally or subtidally; of 22 records for which depth is given in the recent literature, seven are from shore, 11 are from depths between shore and 12 m, and four are from depths greater than 12 m (15, 20–22, 30, and 35 m). Intertidally it appears to be part of the rocky shore fauna, where it lives among rocks or in algae; some specimens have been taken with bryozoans. Subtidally it has been taken on sandy mud, rocks, rocks and coral, rocks and sand, or on sand with calcareous algae, rocks and coral.
Ovigerous females have been collected in January and September (Capart, 1951; Guinot and Ribeiro, 1962; Ribeiro, 1964).
DISTRIBUTION.—Off West Africa, from Madeira, the Cape Verde Islands, Senegal, offshore islands of the Gulf of Guinea, and Angola, intertidal to 35 m, generally in shallower water. Monod (1956:230) commented on its apparent absence on the mainland between Senegal and Angola; he summarized earlier records and reported material from the Cape Verde Islands, Senegal, São Tomé, and Angola. Subsequent records in the literature include the following:

Color: “Rouge orangé avec des taches plus claires” (Capart, 1951:158).
MEASUREMENTS.—Our specimens have carapace widths of 12, 17 and 25 mm.
BIOLOGY.—Glyptoxanthus angolensis is a shallow shelf species, occurring sublittorally in depths between 4–5 m and 40 m, with one record of 35–55 m. Like the West African species of Paractaea, habitats on rough bottom are preferred. The Pillsbury specimens were collected in nodular calcareous algae off Annobon, and the material collected by the Calypso (Forest and Guinot, 1966) was found on the following types of bottom: calcareous algae, 4–5 m; calcareous algae, sand and coral, 7–10 m; rocks and calcareous algae, 20 m; and rocks and coral, 15–40 m. Longhurst (1958) found the species on shelly sand in 25 m off Sierra Leone.
Ovigerous females have been recorded in January and June (Monod, 1956; Forest and Guinot, 1966).
DISTRIBUTION.—West African coast, from scattered localities between Senegal and Angola, including Annobon and São Tomé islands in the Gulf of Guinea; sublittoral, from 4–5 m to 40 m (also 35–55m). Monod (1956) summarized earlier records and reported material from Senegal, Sierra Leone, Congo (Congo Français), and Annobon; records in the literature since 1956 include the following:
Sierra Leone: No specific locality, in 25 m (Longhurst, 1958).
Ghana: Off Accra, sublittorally; Tenkpobo (as Tenpobo), intertidal (Gauld, 1960).
São Tomé: Off Ponta Diogo Nunes, 4–5 m (Forest and Guinot, 1966).

Congo: Pointe Indienne (Rossignol, 1962).
Angola: No specific locality (Forest and Guinot, 1966).
