Abstract

Whether one or two species in the genus Maccullochella should be recognized has been argued for many years. This study, based upon the examination of 210 specimens ranging in size from 31-1235 mm SL reveals that the recognition of two species is warranted. Examination of the type material indicated that the correct name for the Murray cod should be M. peeli (Mitchell, 1838) and the trout cod should be referred to as M. macquariensis (C & V, 1829). This latter species is distinct by virtue of its overhanging upper jaw, straight head slope, longer snout, three pyloric caeca, 14P/21C vertebral regime, grey color, and speckled pattern as opposed to peeli which has equal jaws, a concave head slope, shorter snout, three or four pyloric caeca, 15P/20C vertebral count, green color and mottled pattern. Slight immunoelectrophoretic differences were also detected.
