Description.

Corallum variable in shape, ranging from conical to subcylindrical, sometimes scolecoid, but always attached to substrate by a robust pedicel (PD:GCD = 0.3-0.6) that expands into a thin encrusting base. Calice circular to slightly elliptical (GCD:LCD = 1.0-1.1), with a slightly serrate calicular margin. Theca thick and uniformly hispid. Costae absent. Lower epitheca well developed, covering synapticulotheca, covered in granules. Corallum white.

Septa hexamerally arranged in four complete cycles according to the formula: S1 > S2 > S4 > S3 (48 septa). S1 most exsert. S2 slightly less exsert than S1, and being ¾ the width of S1. Both S1 and S2 bearing straight to slightly sinuous axial margins. Higher cycle septa (S3-4) becoming progressively less exsert and smaller. S3 is ½ the width and less sinuous than S2. S4 rudimentary, and bear the least sinuous but slightly dentate axial margins. Septal faces granular. Fossa deep, containing a rudimentary columella.

Distribution.

Regional: Southern to eastern margin of South Africa, extending from off Gansbaai towards Kosi-Kumpungwini (Sifungwe) Estuary (8 km south of Ponta Do Ouro: Mozambique); 50-775 m. Elsewhere: Only known from South Africa.

Remarks.

Pourtalopsammia togata   appears to be endemic to South Africa, and records presented herein extend its distribution further south towards Gansbaai. Furthermore, the genus is monotypic and closely resembles Trochopsammia   Pourtalès, 1878 but differs in having a hispid theca ( Cairns and Keller 1993; Cairns 2001).
