New species of the New Caledonian endemic genus Agnotecous (Orthoptera, Grylloidea, Eneopterinae, Lebinthini)

Abstract

To analyze the pattern of endemism of Eneopterinae crickets (Orthoptera, Grylloidea, Eneopteridae) in New Caledonia, available data sets have been completed by intensive field work and by the study of museum collections. Five new species of Agnotecous Saussure, 1878 (A. humboldti Robillard, n. sp., A. nekando Robillard, n. sp., A. minoris Robillard, n. sp., A. petchekara Desutter-Grandcolas, n. sp., A. pinsula Robillard, n. sp.) and one new subspecies (A. brachypterus pocquensis Desutter-Grandcolas, n. ssp.) are described here from Grande Terre and Île des Pins. These new data (1) enhance the richness of Agnotecous in New Caledonia, with a total of 20 known species for the genus; (2) complete the distributional data about species sympatry; (3) further document the distribution of the genus in the archipelago; and (4) confirm the acoustic properties of Agnotecous calling songs.
