Cladistic analysis of the trilobite subgenus Acanthopyge (Lobopyge) has not been previously attempted, apart from an inferred phylogeny of the Lichida by Thomas and Holloway (1988, Philos. Trans. R. Soc. London B Biol. Sci. 321, 179–262). Results of two separate analyses with variable taxonomic sampling show a possible cosmopolitan affinity for Australian Devonian species of A. (Lobopyge) and corroborate the placement of A. (Lobopyge) rohri in A. (Lobopyge). Benelopyge is a junior subjective synonym of A. (Lobopyge).
