Abstract.The myrmicine ant genusLophomyrmexis fully revised and transferred from tribe Pheidologetonini to Pheidolini (tribal transfer: Pheidolini, senior synonym of Lophomyrmecini syn.n.). Ten species are recognized, which are placed into two species groups. Thequadrispinosusgroup, characterized by the presence of pronotal teeth or spines, includesbirmanus, kalisp.n.,opacicepsstat.n. (=javanasyn.n.),quadrispinosus(=taprobanaesyn.n.) andtaivanaestat.n. Thebedotigroup, in which the pronotum is dorsolateraly marginate, includesambiguussp.n.,bedoti, longicomissp.n.,lucidusstat.n. andstrialulussp.n. A key to the worker caste is presented and descriptions of known sexual forms are given.
