Recent study has found a relationship between this species and an Asian filmy-fern species, Crepidomanes schmidtianum. Both share the same chloroplast genome. The relationship is uncertain.
In 2011, Atsushi Ebihara and Alan S. Weakley transferred Trichomanes intricatum to Crepidomanes intricatum based on the chloroplast molecular sequence data.
