SAM_H3038 (5 fragments): Easternmargin, 17 kmfrom St. Lucia Estuary/ 16 kmoff Mfolozi Estuary, 28°21'53.99"S, 32°34'36.00"E;  775-825 m. SAM_H3039 (10 fragments): Easternmargin, 36 kmoff Port Shepstone/ 49 kmoff Mtentu Estuary, 30°43'11.99"S, 30°48'47.99"E;   900 m. SAM_H3040 (1 fragments): Southernmargin, 36 kmfrom Port Shepstone/ 29 kmoff Mhlabatshane Estuary, 30°43' 11.99" S, 30°48'47.99"E;   780 m.  Description. Corallum colonial, with delicate distal branches. Colonies usually bushy but distal branches uniplanar, with sympodially arranged corallites. Corallites circular, reaching ≤ 3.0 mm in CD, with slightly serrated calicular margin. Costae thin and prominent near calicular edge, usually corresponding to higher cycle septa. Coenosteum finely granular, longitudinally striated. Corallum light beige to white. Septa thin and hexamerally arranged in three complete cycles according to the formula: S1> S2> S3 (24 septa). S1 highly exsert, extending towards columella deep in fossa with dentate and sometimes laciniate axial margin. S2 less exsert, half the width of S1, and have dentate axial edges. S3 rudimentary and discontinuous. Fossa deep, containing a poorly developed papillose columella.  Distribution. Regional: Southern and Eastern margins of South Africa, off Still Bay ( Boshoff 1981) extending towards St Lucia; 780-900 m. Elsewhere: Cosmopolitan, apart from Antarctica ( Alcock 1898; von Marenzeller 1904a ; Gardiner and Waugh 1938; Zibrowius 1980; Cairns 1979, 1982, 1984; Cairns and Keller 1993 ; Cairns 2004a); 15-1950 m.  Remarks.   Madrepora oculatais one of the most well-studied framework building azooxanthellate coral species, and has been reported worldwide (apart from Antarctica). The first record from South Africa was identified as  Lophelia exigua Pourtales, 1871 ( Boshoff 1981) (ORI_DIIIf1), but two localities were listed, making it unclear where the sample was collected. Nonetheless, both of the stations fall within the southern margin of South Africa. One of the examined specimens (SAM_H3038) is attached to hexactinellid sponge spicules 2021-01-01 2021-12-31 2021-01-01 St. Lucia Mfolozi Estuary 800 -28.364998 Locality 1 32.576664 Estuary 1 2021-01-01 2021-12-31 2021-01-01 Saint Lucia Mtentu Estuary 900 -30.719997 Eastern 1 30.81333 Port Shepstone 900 2021-01-01 2021-12-31 2021-01-01 Saint Lucia Mhlabatshane Estuary 780 -30.719997 Southern 1 30.81333 Port Shepstone 780
