An endemic Australian genus with six species, all found only along the southern coast. Body shallow (11-18% SL), very elongate, gradually tapering to shallow caudal peduncle; small head (17-23% SL), eye and mouth (upper jaw 32-40% HL), gape nearly horizontal; scales tiny, not overlapping; lateral line pores not associated with scales, originating above opercle, followed by series of pit‑like depressions; dorsal and anal fins continuous with very elongate bases and uniform heights, both broadly joined by membrane to caudal fin, dorsal origin above opercular edge; caudal fin rounded to pointed; pectoral and pelvic fins much longer than eye diameter (Hoese et al. 2008).
