Abstract: A revision of the endemic New Caledonian tiger beetle genus Caledonica Chaudoir, 1860 is presented based on the examination of more than 600 specimens including the relevant type material. Neotype is designated for Distipsidera mediolineata Lucas, 1862 and Distipsidera Mniszechii Thomson, 1856 as the original type material is lost. Oxycheila arrogans Montrouzier, 1860 is recognized as an unavailable name because it was proposed in synonymy and is replaced by Caledonica tuberculata Fauvel, 1882, stat. restit. The following new synonymy is proposed: Oxycheila affinis Montrouzier, 1860 = Caledonica affinis var. lerati Fleutiaux, 1911, syn. nov. Caledonica luiggiorum sp. nov. and C. rivalieriana sp. nov. are described as new to science. Males of two species, C. longicollis Fauvel, 1903 and C. rubicondosa Deuve, 2006, are described for the first time. Redescriptions of all species are given. A dichotomous key to species and subspecies is provided, and a brief history of the taxonomy and nomenclature of this genus is also given. Biology and distribution of most species and behaviour of adults in their biotopes, based on the authorʼs own field research and observations during his three surveys in New Caledonia are presented. Each species is described in detail; its habitus and diagnostic characters are illustrated in colour photographs.
