  abstract = {{I}slands are bounded areas where high endemism is explained either by allopatric speciation through the fragmentation of the limited amount of space available, or by sympatric speciation and accumulation of daughter species. {M}ost empirical evidence point out the dominant action of allopatric speciation. {W}e evaluate this general view by looking at a case study where sympatric speciation is suspected. {W}e analyse the mode, tempo and geography of speciation in {A}gnotecous, a cricket genus endemic to {N}ew {C}aledonia showing a generalized pattern of sympatry between species making sympatric speciation plausible. {W}e obtained five mitochondrial and five nuclear markers (6.8 kb) from 37 taxa corresponding to 17 of the 21 known extant species of {A}gnotecous, and including several localities per species, and we conducted phylogenetic and dating analyses. {O}ur results suggest that the diversification of {A}gnotecous occurred mostly through allopatric speciation in the last 10 {M}yr. {H}ighly microendemic species are the most recent ones (<2 {M}yr) and current sympatry is due to secondary range expansion after allopatric speciation. {S}pecies distribution should then be viewed as a highly dynamic process and extreme microendemism only as a temporary situation. {W}e discuss these results considering the influence of climatic changes combined with intricate soil diversity and mountain topography. {A} complex interplay between these factors could have permitted repeated speciation events and range expansion.},
