Ischyropsalidoidea, comprising the families Ceratolasmatidae, Ischyropsalididae and Sabaconidae, has been investigated in detail. It is not clear whether Ceratolasmatidae and Sabaconidae are each monophyletic, as the ceratolasmatid Hesperonemastoma groups with the sabaconid Taracus in molecular analyses. All other families are grouped under Troguloidea. Laniatores There is not yet a proposed phylogeny for the whole group of Laniatores, although some families have been researched in this regard. The Laniatores are divided into two infraorders, the "Insidiatores" Loman, 1900 and the Grassatores Kury, 2002. However, Insidiatores is probably paraphyletic. It consists of the two superfamilies Travunioidea and Triaenonychoidea, with the latter closer to the Grassatores. Alternatively, the Pentanychidae, which reside in Travunioidea, could be the sister group to all other Laniatores. The Grassatores are traditionally divided into the Samooidea, Assamioidea, Gonyleptoidea, Phalangodoidea and Zalmoxoidea. Several of these groups are not monophyletic. Molecular analyses relying on nuclear ribosomal genes support monophyly of Gonyleptidae, Cosmetidae (both Gonyleptoidea), Stygnopsidae (currently Assamioidea) and Phalangodidae. The Phalangodidae and Oncopodidae may not form a monophyletic group, thus rendering the Phalangodoidea obsolete. The families of the obsolete Assamioidea have been moved to other groups: Assamiidae and Stygnopsidae are now Gonyleptoidea, Epedanidae reside within their own superfamily Epedanoidea, and the "Pyramidopidae" are possibly related to Phalangodidae.
