Etymology: Akheilos: Named for the Greek mythological sea daemon Akheilos, who was a handsome boy until turned into a shark by the goddess Aphrodite as punishment for boasting that he was more beautiful than she (no deep meaning or special relevance to the shark, simply a “cool name” that “just seemed to click”; William T. White, pers. comm.) (See ETYFish); suwartanai: In honor of Atjep Suwartana, first director of the Research and Development Center of Oceanology, Indonesian Institute of Sciences in Ambon (where the second author works) (See ETYFish).

This moderately small scyliorhinid catshark is distinguished by the following set of characters: a moderately long precaudal tail region (tail much longer than trunk); dorsal fins are of similar size and shape; snout short and narrowly parabolic; eyes are large and narrowly oval (length 5.0 times in head length), broad suborbital grooves; nostrils are oblique with triangular anterior nasal flaps not reaching to mouth and distinct but low posterior nasal flaps; mouth is broadly rounded, its width 1.2 times preoral length; upper and lower labial furrows are well developed, uppers not reaching midpoint between mouth corner and posterior margin of nostril; jaws with ~60 upper and ~53 lower tooth rows, teeth are mostly multicuspid, posterolaterals not strongly differentiated from anterolaterals; caudal fin ventral lobe is low but distinct; claspers long and slender, glans elongate, long and low envelope present, cover rhipidion small without an anterior fold or tab, pseudosiphon small and slit-like; with supraorbital crests on cranium; precaudal vertebral centra 96, total centra ~137. Colouration: pale brown with numerous rusty brown spots, small brown spots forming two indistinct saddles on dorsal surface of predorsal body, broken ocellus-like marking on side behind pectoral fins and under each dorsal fin (Ref. 120897).
Depth of occurrence unknown. Stomach contained several anterior sections of a small snake eel (Ophichthidae) (Ref. 120897).
