. Within a framework for historical analysis of Eneopterinae biogeography the New Caledonian endemic cricket genus Agnotecous Saussure, 1878 is revised: the eight already known species are diagnosed and six new species described, A. azurensis Desutter‐Grandcolas sp.n. , A. chopardi Desutter‐Grandcolas sp.n. , A. clarus Desutter‐Grandcolas sp.n. , A. doensis Desutter‐Grandcolas sp.n. , A. meridionalis Desutter‐Grandcolas sp.n. and A. occidentalis Desutter‐Grandcolas sp.n. Four species groups are characterized by male genitalic structures. Identification keys are provided for both males and females. A cladistic analysis was performed using fifty‐eight morphological characters. The two resultant topologies, which differ only in topology of three apical species, support the monophyly of Agnotecous and that of the four species groups. Preliminary hypotheses of Eneopterinae historical biogeography are derived from phylogenetic and distributional data.
