Barnard, 1926
Diagnosis:
Anterior margin of carapace between frontal horns straight, with single pair of strong submedian spines, no median spine present; rest of margin as well as inner margin of horns unarmed or with two very small spinules.
Epistome with tubercles on the anterior margin; anterolateral corners with a single tubercle.
Type:
Type locality: Off Mozambique, "25° S., 33°10'E., 406 metres, mud". This position cited by Barnard (1926) is definitely incorrect, as it would be on dry land; it is possible that a number of minutes has to be added to 25° S. Holotype male in SAM, no. A 10684 (in alcohol; condition good).
Geographical Distribution:
The species has been reported from East Africa (Mozambique and Somalia).
Habitat and Biology:
Found in deep water (406 m), but also in 59-61 m depth. Reported from a muddy substrate.
Size:
Total body length 9.5 cm. Carapace length 3 cm.
Interest to Fisheries:
So far none. Very little is known of this species of which only very few specimens have been found.
Remarks:
Specimens reported under the name P. mossambicus from India and the Philippines have here, provisionally, been assigned to P. waguensis. The status of these two species, however, needs further investigation.
