Global models of species diversity rarely focus on insects and none attempt to address unknown, undescribed diversity. We assembled a database representing about 13,000 records for ant generic distribution from over 350 regions that cover much of the globe. Based on two models of diversity and endemicity, we identified regions where our knowledge of ant diversity is most limited, regions we have called “hotspots of discovery.” A priori, such regions might be expected to be remote and untouched. Instead, we found that the hotspots of discovery are also the regions in which biodiversity is the most threatened by habitat destruction. Our results not only highlight the immediate need for conservation of the remaining natural habitats in these regions, but also the extent to which, by focusing on wellknown groups such as vertebrates, we may fail to conserve the far greater diversity of the smaller species yet to be found.10aants10aglobal models1 aGuénard, B.1 aWeiser, M., D.1 aR., Dunn, R.  uhttps://singaporeants.myspecies.info/node/87801782nas a2200229   4500008004100000245018000041210006900221260000900290300001200299490000900311520102600320653001501346653001701361653002601378653001401404100001601418700001701434700001701451700001701468700001701485856005001502       2010                        eng d00aOn the evolution of the species complex Pachycondyla chinensis (Hymenoptera: Formicidae: Ponerinae), including the origin of its invasive form and description of a new species0 aevolution of the species complex Pachycondyla chinensis Hymenopt  c2010  a39 - 500 v26853 aAnts are one of the most successful and widespread organisms in the world. Although ants of the genus Pachycondyla(Hymenoptera: Formicidae: Ponerinae) are predominantly tropical in distribution, Pachycondyla chinensis (Emery) is especially abundant in temperate zones in Asia. Recently, P. chinensis has also become an abundant invasive ant species in the United States. However, it was well-known that the Pachycondyla chinensis species complex remained unresolved. Our molecular and morphological results allow us to distinguish two species in the species complex: the species P. chinensis and the new cryptic species P. nakasujii sp. nov., and these two species are widely and sympatrically distributed and abundant in temperate forests in Japan. Moreover, phylogenetic analysis showed that P. chinensis has been introduced into the United States from Japan. In conclusion, our finding of the new species P. nakasujii suggests that much remains undiscovered even in biologically fascinating and well-studied organisms.10aFormicidae10aPachycondyla10aPachycondyla chinesis10aPonerinae1 aYashiro, T.1 aMatsuura, K.1 aGuénard, B.1 aTerayama, M.1 aDunn, R., R.  uhttps://singaporeants.myspecies.info/node/869
