Labellum 15–20 mm long when flattened out, tube erect, about as long as lamina, auricles wide and opening downwards obscured by labellum lamina; lamina acutely recurved, expanded into trumpet-shaped orifice, crimson-streaked along veins with reddish bristles in front of boss, margins coarsely toothed and directed forwards or spreading; central boss reddish, inconspicuous, convex (not channelled); callus entire.

HSF, WaP. Scattered in near-coastal areas of Victoria west from Wilsons Promontory where found in swamps and watercourses dominated by Leptospermum lanigerum.

This is the last species of Corybas to flower in Victoria.

Can be distinguished from C. diemenicus by the labellum auricles which are obscured by the lamina, the later flowering period and unique habitat.
