Two new species of acropomatid fishes, Malakichthys levis and M. mochizuki, are described on the basis of specimens collected from the waters around northern Australia. The two species are easily distinguishable from other species of Malakichthys by no paired spines
on the chin. Although the new species are very similar to each other, they are differentiated by the lamellar septum of first anal-fin pterygiophore (absent in M. levis, present in M. mochizuki), the counts of the gill rakers on the lower arm (20–22 in M. levis,
23–25 in M. mochizuki) and the transverse scale rows above the lateral line (6–7 in M. levis, 4–5 in M. mochizuki).
