Etymology: Cephaloscyllium: cephalus, from kephale (Gr.), head, referring to its very broad and depressed head; skylion, Greek for dogfish or small shark (See ETYFish)stevensi: In honor of John Stevens (b. 1947), whose 1994 work (with Peter Last) on Australian sharks was the “foundation for research that led to the descriptions of 37 new chondrichthyan fishes, including 11 species of Cephaloscyllium” (See ETYFish).
Eponymy: Dr John Donald Stevens (d: 1947) is a biologist and ichthyologist who was a Senior Principal Research Scientist with CSIRO Marine and Atmospheric Research, originally in Sydney (1979–1984) and subsequently in Hobart, Tasmania, Australia (1984–2011). [...] (Ref. 128868), visit book page.

Similar to its congeners, this species is most easily distinguished by its color pattern: gray-brown above, whitish ventrally, mottled with brown and whitish spots of variable size over head and body, including ventrally; 6 large dark brown saddle blotches dorsally on head and body and 3 on caudal fin; first four dorsal dark blotches connecting or leading obliquely to other dark blotches below; small white spots most distinct within or at edges of dark brown blotches (Ref. 86282).
