  abstract = {{T}he grasshopper genus {C}aledonula, endemic to {N}ew {C}aledonia, was studied to understand the evolution of species distributions in relation to climate and soil types. {B}ased on a comprehensive sampling of 80 locations throughout the island, the genus was represented by five species, four of which are new to science, of which three are described here. {A}ll the species have limited distributions in {N}ew {C}aledonia. {B}ioclimatic niche modelling shows that all the species were found in association with a wet climate and reduced seasonality, explaining their restriction to the southern half of the island. {T}he results suggest that the genus was ancestrally constrained by seasonality. {A} molecular phylogeny was reconstructed using two mitochondrial and two nuclear markers. {T}he partially resolved tree showed monophyly of the species found on metalliferous soils, and molecular dating indicated a rather recent origin for the genus. {A}daptation to metalliferous soils is suggested by both morphological changes and radiation on these soils. {T}he genus {C}aledonula is therefore a good model to understand the origin of microendemism in the context of recent and mixed influences of climate and soil type.},
