A temperate Australian species known only from northern Tasmania, between Duck River (145°08'E) and Greens Beach (146°45'E); benthic, inhabiting sandy or muddy bottomed estuaries and the lower reaches of freshwater streams.

Features

D VI-VIII; 13-16; A 12-14; C (segmented rays) 17, (branched rays) 12-14; P 17-19; V I, 5; Vert 12 + 17-19; GR 1-2 + 6-8 = 8-10.
Body slender, depth 9.7-10.6 in SL Head short, length 3.9-4.2 in SL. Anterior nostril at end of short tube, about midway between upper margin of upper lip and eye, about 2 nostril diameters above upper lip; posterior nostril with raised rim, immediately before anterior margin of eye. Eye about equal to snout in adult. Mouth small and oblique; reaching to below middle of eye in male and below anterior quarter of eye in female; upper margin of upper jaw in line with middle of eye; teeth in upper jaw conical, those in outer row close-set; few smaller teeth anteriorly in second row; lower jaw teeth similar to upper jaw teeth, but with outer row teeth more wide-set; tongue tip truncate to slightly emarginate. Gill opening restricted to pectoral base. Head pores absent.
Body partly scaled; small patch of vertically elongate scales behind pectoral base on sides of belly, lateral line absent; longitudinal count 6-10, and isolated patch of few scales on caudal peduncle, sometimes extending forward in narrow wedge to under end of second dorsal fin, longitudinal count 3-14; rest of body including pectoral base, prepelvic area and belly naked; scales mostly ctenoid; longitudinal scales 10-24.
Two dorsal fins; first dorsal fin short-based with low rounded margin; all dorsal and anal fin rays usually segmented. Pectoral fin with rounded margin, reaching to point below middle of first dorsal fin. Pelvic fins fused to form large cup-shaped disc reaching to below end of first dorsal fin, well short of anus.

Size

To around 3.5 cm SL.

Colour

Transparent to pale brown, with row of about 9 small fawn markings along lateral midline, many vertically elongate; other fawn markings dorsally; thin black vertical bar from ventral margin of eye to posterior end of jaws; diffuse black spot behind posterior margin of eye and similar diffuse black mark on dorsoposterior margin of operculum. Fins mostly opaque; dorsal fins usually with black spots forming oblique lines, caudal fin sometimes with wavy vertical grey bars.

Likely to be oviparous, benthic spawners.
