Abstract: Indo-Pacific members of the speciose and morphologically confusing group of Camponotus ants that resemble C. maculatus (Fabricius, 1782) have recently been the subject of a molecular phylogeny, and that analysis is used here as guidance to update the taxonomy of the Micronesian species. It is now known that Micronesian and some Melanesian specimens previously identified as C. chloroticus Emery, 1897 are not closely related to Polynesian, Fijian, and Melanesian specimens identified by the same name, and that the form on Palau presently identified as C. irritans kubaryi Mayr, 1876 is not closely related to C. irritans (Smith, F., 1857). We therefore examined the morphologies of 185 specimens previously assembled for molecular analysis, plus five C. chloroticus and two C. kubaryi syntypes. Principal component analyses were conducted to understand shape differences and match modern specimens to types. The syntypes of C. chloroticus, which are from Tonga and southeastern New Guinea, matched the species that is today represented by collections from Polynesia, Fiji, and Melanesia. Thus, specimens mostly from Micronesia and formerly identified as C. chloroticus are here described as Camponotus micronesicus sp.n. In addition, C. kubaryi stat. rev. is returned to species status, and Camponotus tol sp.n., a new species from the Micronesian island of Chuuk, is described.
