Các tia vây lưng cứng (tổng cộng) : 0. A brown-spotted legskate with smooth skin and a short slender tail less than body length; snout angular with tiny filament; pectoral disc with rounded corners; no large thorns on denticles except for alar spines on adult males (Ref. 5578). Legskates have pelvic fins separated into a mobile leg-like front lobe, and a rear lobe that may be fused to the tail base (Ref. 5578). Mottled brown and white with scattered ocelli dorsally; uniform pale ventrally (Ref. 6510). Papillae and rostral filament dark brown (Ref. 6510).
Possibly the smallest southern African skate (Ref. 5578). Found on the upper slope (Ref. 5578).
