The 2009 Singapore Flora Checklist listed 10 species of ferns in this family. All of them are in the genus Diplazium. In 2010, a new species (Athyrium accedens) in this family was discovered by Joseph Lai. In the same blog, he indicated that we have now 11 species of Athyrium in Singapore. It seems to imply that the genus Diplazium has been changed to Athyrium. However, information in the Plant List website did not seem to indicate so. Hence, I have kept to Diplazium for the other 2 species in my website.
