Short description

Dorsal soft rays (total): 7 - 9; Anal soft rays: 7 - 11; Vertebrae: 47 - 51. Distinguished from all other congeners in New Zealand in having only 4-6 pelvic fin rays and only 11-14 principal caudal rays (Galaxias pullus has 14 principal caudal rays, but has 7 pelvic fin rays, and is much more stoutly built; Galaxias cobitinis has only 5 pelvic fin rays, usually has 15 principal caudal fin rays, and has a distinctly protruding lower jaw). This species has distinctly rounded snout when viewed from both dorsal and lateral perspective (Ref. 75601).

Collected mainly from small gravelly riffles in small streams. This fish appears to be cryptic (Ref. 75601).
