The type of D. austrophilippina has a less tapering apical lamina than the other type, and paler hairs on lower surface of rachis. In 1975 I included D. urdanetensis Copel. also as a synonym of the present species, but it lacks very small basal reduced pinnae. Apart from size, there is little to distinguish this from S. lobatus.
