One of several Apristurus with the first dorsal fin half the area of the second or less. For other characters see diagnostic features and key to species.
Body slender, / tapering gradually to head. Snout long, very broad, and bell-shaped, preoral snout about 8 11% of total length; gill slits small, much less than eye length; gill septa without projecting medial lobes or pleats but deeply incised; eyes small, about 4% of total length; nostrils broad, their width about equal to internarial space; incurrent and excurrent apertures small and oval, anterior nasal flaps low and angular; mouth short, moderately large, and very broadly arched, with dental bands not expanded and with lower ones falling just behind uppers; mouth and labial furrows below eyes; labial folds not enlarged, with lowers diagonal to body axis. Interdorsal space about a third greater than first dorsal base, two-thirds of preorbital snout; first dorsal fin about half the area of second, base of first about three-fourths the length of second; origin of first dorsal slightly behind pelvic insertions; second dorsal insertion well in front of anal insertion; pectoral fins rather small, anterior margins about 12% of total length; inner margins long, nearly length of pectoral bases; interspace between pectoral and pelvic bases short, slightly less than preorbital length and about 10% of total length; pelvic fins low and angular; anal fin moderately long, low and angular, slightly more than 4 times as long as high, its base about equal to prebranchial space and 18% of total length; caudal fin elongated and fairly broad, without a crest of enlarged denticles on dorsal caudal margin. Lateral trunk denticles of body with crowns fairly flat and close-set, surface fairly smooth and not with a feltlike or fuzzy texture. Colour dark brown without conspicuous white margins on fins. Adult size unknown.
Known only from the type locality (Sipadan Island, vicinity of Sibuko Bay, southern Sulawesi (Celebes).
Habitat and Biology:
A rare, deepwater catshark, known only from the holotype.
Over 29.7 cm maximum.
Interest to Fisheries:
The above account and illustration is based on the writer's examination of the holotype. Springer (1979) noted that this species may be a synonym of A. platyrhynchus, but hesitated to synonymize it; A. verweyi is provisionally retained here.
