More Info


Distribution

Known only from the Flinders Ranges, South Australia, and the Bulloo Basin, Queensland. Inhabits spring-fed, rocky pools of freshwater streams that flow through steep-sided valleys or lowland creeks with muddy substrates.

Features

Dorsal fin VIII or IX, I, 9-12 (usually VIII, I, 11); Anal fin I, 9-13 (usually 11-12); Caudal fin (segmented rays) 15, (branched rays) 15; Pectoral fin 15-17 (usually 16); Pelvic fin I, 5; Transverse scales 13; longitudinal scale series 34-39; Predorsal scales 17-21; Gill rakers 2 + 8 = 10; Vertebrae 14-16 + 15-18 = 31-32.

Body elongate, laterally compressed, more strongly posteriorly; depth 3.7-5.1 in SL; caudal peduncle relatively elongate. Head bluntly rounded with gently arched snout and nape profile; length 2.8-3.2 in SL. Eye diameter 12.0-15.4 in SL. Lower jaw protruding, mouth oblique, reaching to anterior edge of pupil; jaws with villiform, posteriorly curved teeth, in dense bands, outer row enlarged; palate without teeth. Gill opening extending nearly to below rear margin of eye. Sensory pores absent on head, but well developed system of papillae arranged in multiserial bands. Sexual dimorphism generally inconspicuous.

Head and body covered with scales, except lips, snout tip, preorbital region, lower jaw, and chin; those on head, predorsal region, breast, uppermost part of back and bases of caudal and pectoral fins cycloid, remainder finely ctenoid; lateral line absent.

Two dorsal fins, first rounded and lower than second, with slender, flexible spines; second dorsal and anal fins similar and opposite. Pectoral fin rounded. Pelvic fins separate, pointed. Caudal fin rounded.

Size

To around 13 cm SL.

Colour

Brownish, cream to pale tan ventrally, upper surface of head with dark brown speckling; head with three reddish-brown diagonal stripes, and short, backward slanting, diagonal stripe from upper rear corner of eye; middle of body with scattered, moderate sized reddish-brown spots, concentrated mid-laterally; 8-9 faint broad, blue-grey bars or blotches across middle of side, interspersed with narrow tan bars; moderate sized, blackish spot at middle of caudal fin base. First dorsal fin dusky grey with yellowish outer margin and faint yellow stripe near base; second dorsal dusky grey to purplish brown with yellowish margin, 4-5 small red-brown spots at base and several smaller red-brown spots, mainly across middle of fin; anal fin yellowish brown with narrow white outer margin and whitish basal stripe punctuated with several small red-brown spots; caudal fin dusky grey to purplish brown with numerous, small red-brown spots; pelvic and pectoral fins tan to semi-translucent.

Feeding

Likely to feed on insect larvae and small crustaceans.

Biology

Oviparous, benthic spawners, spawning occurring at temperatures over 20ºC when females deposit between 200 and 800 adhesive eggs onto a hard substrate; males guard and fan eggs until hatching. Larvae hatch after around 7 days at approximately 5 mm TL.

Etymology

The specific name clivicola is Latin meaning ‘hill-dweller’ in reference to the Flinders Ranges habitat.
