A taxonomic revision of the genus Aneorhachis Kleine 1923 (Coleoptera: Brentidae) and a phylogenetic analysis of species belonging to this genus are carried out. The genus Ipsopisthius Kabakov 2001 is synonymised with Aneorhachis, and two new combinations are proposed: Aneorhachis hirta (Kabakov 2001), n. comb. and A. incerta (Kleine 1935), n. comb. Higonius nitens Goossens 2008 is synonymized with A. incerta. One new species is described from New Guinea, A. papuana n. sp. All the species are redescribed and type-specimens are illustrated; an identification key is proposed. A maximum parsimony analysis is provided on the base of 23 characters from adult morphology. This analysis confi rms the monophyly of the genus and seems to show that Aneorhachis originated on continental Asia and then spread out eastward to colonize Pacific islands.
