“…A clear example in the Caribbean is the local extinction of Neivamyrmex army ants [16], which are blind, nomadic predators. Specialized niche loss in this region also applies to the extinction of the trap-jaw ants Acanthognathus [35] and subterranean predators such as Acanthostichus [36].…”

Background Ponerine ants are almost exclusively predatory and comprise many of the largest known ant species. Within this clade, the genus Neoponera is among the most conspicuous Neotropical predators. We describe the first fossil member of this lineage: a worker preserved in Miocene-age Dominican amber from Hispaniola. Results Neoponera vejestoria sp. nov. demonstrates a clear case of local extinction—there are no known extant Neoponera species in the Greater Antilles. The species is attributable to an extant and well-defined species group in the genus, which suggests the group is older than previously estimated. Through CT scan reconstruction and linear morphometrics, we reconstruct the morphospace of extant and fossil ants to evaluate the history and evolution of predatory taxa in this island system. Conclusions The fossil attests to a shift in insular ecological community structure since the Miocene. The largest predatory taxa have undergone extinction on the island, but their extant relatives persist throughout the Neotropics. Neoponera vejestoria sp. nov. is larger than all other predatory ant workers known from Hispaniola, extant or extinct. Our results empirically demonstrate the loss of a functional niche associated with body size, which is a trait long hypothesized to be related to extinction risk.

China is one of the largest countries in the world and offers an incredible diversity of ecosystems and species. Howeverthe distribution of many insect species in China is still poorly known. Here, through a bibliographical review, we synthe-size a species list of native and exotic ants (Hymenoptera: Formicidae) for 23 provinces of the People’s Republic of Chinaand eight surrounding regions. To date, no fewer than 939 valid named species and subspecies within 103 genera are listedfrom China. However, comparisons with other regions suggest that this list is still incomplete at both provincial and na-tional scales based on the diversity of surrounding regions and the number of undescribed species reported in the literature.Although the species list generated here is not and cannot be exhaustive, we hope that it will facilitate future discovery, revision and conservation of Chinese ants.

The ant genus Rhopalothrix is a rare inhabitant of wet forest leaf litter and soil. We propose a monophyletic R. isthmica clade that is restricted to the Neotropics, contains most of the species in the genus, and has its center of abundance and diversity in Central America. Thirteen species are recognized in the R. isthmica clade, of which eight are described as new and three are redescribed. A key to species in the R. isthmica clade is provided, and the following eight new species are described: R. andersoni Longino & Boudinot, sp. nov., R. apertor Longino & Boudinot, sp. nov., R. atitlanica Longino & Boudinot, sp. nov., R. megisthmica Longino & Boudinot, sp. nov., R. nubilosa Longino & Boudinot, sp. nov., R. subspatulata Longino & Boudinot, sp. nov., R. therion Longino & Boudinot, sp. nov., and R. triumphalis Longino & Boudinot, sp. nov.. Queens are newly associated with workers for three Central American species. New synonymy is proposed for Rhopalothrix plaumanni Brown & Kempf, 1960 = R. acutipilis Kempf, 1962, syn. nov.
