The genus Rocalia TAKEUCHI is transferred from the subfamily Heterarthrinae to the Selandriinae because of such unique biological characters as the piercing-type of oviposition and the host-plant association with ferns. A new tribe Rocaliini is erected for this single genus based on derivative morphological characters, viz. the large posttergite, the deeply incised propodeum, the absence of prepectus and the tridentate mandible, on the peculiar larval feeding habit restricted to the spores of ferns, and on the specialized karyotypes consisting of many telocentric chromosomes. A second species, R. japonica n. sp., is described from Japan.
