Recent phylogenetic analyses of Eumolpinae of the south Pacific suggest that Dematochroma is
paraphyletic: the type species, the Lord Howe endemic D. picea, is placed in a clade including New Caledonian endemic genera Taophila and Tricholapita, which is sister to another clade including other New Caledonian Eumolpinae genera, the New Caledonian species of Dematochroma as well as the New Zealand endemic Atrichatus. Because of these findings, Gómez-Zurita and Pàmies-Harder (2022) preferred to transfer the New Caledonian species of Dematochroma to other genera.[7] For instance, the genus Thasycles Chapuis, 1874, which was for a long time treated as a synonym of Dematochroma, was reinstated as a valid genus,[7] and a new genus Dematotrichus was established for Dematochroma pilosa and closely related species.[8]
