Abstract Scales and dermal bone fragments of a new palaeoniscoid have been found in shallow water marine limestones (Lochkovian; pesavis conodont zone) from the Trundle beds of central New South Wales; Australia. The flank scales are rhombic; with a weakly developed antero-dorsal process. The surface ornament comprises discrete; smooth; dentine ridges and triangular dentine patches; the latter are concentrated along the anterior edge of the scale. A thin ganoine layer is sometimes present. The inner surface of anterior flank scales bears a well-developed keel parallel to the anterior edge of the scale. There is no peg or socket. The new scales have more primitive characters than all palaeoniscoids except Naxilepis.
