A revised generic description is provided for workers and gynes; males remain unknown. Morphological patterns combined with geographical data led to the recognition of 16 species, of which 10 are here described as new: L. amazonicus sp. n., L. fernandezi sp. n., L. grandis Fernández & Baena, L. haskinsi Smith, L. lattkei sp. n., L. longinodus Fernández & Baena, L. longinoi sp. n., L. mackayi sp. n., L. nordestinus sp. n., L. pilosus Weber, L. laticeps sp. n., L. platynodus sp. n., L. plaumanni Borgmeier, L. regularis sp. n., L. scrobiculatus Wheeler, and L. victori sp. n. The gynes of L. grandis, L. haskinsi, and L. pilosus are described for the first time. Illustrated identification keys for workers, distribution maps, and high resolution illustrations are supplied for all species. Some Lachnomyrmex species are relatively common in the leaf-litter of submontane wet forests in Central and South America; others remain known by very few individuals. The relatively small and apparently monogynic Lachnomyrmex colonies inhabit small nests in the ground, among rotten leaves and inside fallen logs. Workers generally forage alone on the ground or within the leaf litter, but have been recorded also on tree trunks, and apparently do not recruit nestmates.

Alex <br/> <br/>Abstract: Species inventories are essential for documenting global diversity and generating necessary material for taxonomic study and conservation planning. However, for inventories to be immediately relevant, the taxonomic process must reduce the time to describe and identify specimens. To address these concerns for the inventory of arthropods across the Malagasy region, we present here a collaborative approach to taxonomy where collectors, morphologists and DNA barcoders using cytochrome c oxidase 1 (CO1) participate collectively in a team-driven taxonomic process. We evaluate the role of DNA barcoding as a tool to accelerate species identification and description. This revision is primarily based on arthropod surveys throughout the Malagasy region from 1992 to 2006. The revision is based on morphological and CO1 DNA barcode analysis of 500 individuals. In the region, five species of Anochetus (A. boltoni sp. nov., A. goodmani sp. nov., A. grandidieri, and A. madagascarensis from Madagascar, and A. pattersoni sp. nov. from Seychelles) and three species of Odontomachus (O. coquereli, O. troglodytes and O. simillimus) are recognized. DNA barcoding (using cytochrome c oxidase 1 (CO1)) facilitated caste association and type designation, and highlighted population structure associated with reproductive strategy, biogeographic and evolutionary patterns for future exploration. This study provides an example of collaborative taxonomy, where morphology is combined with DNA barcoding. We demonstrate that CO1 DNA barcoding is a practical tool that allows formalized alpha-taxonomy at a speed, detail, precision, and scale unattainable by employing morphology alone. <br/> <br/>Description: This is an experimental paper to demonstrate the possibilities of mark-up, and is the first of this kind in PLOS One Wed, 28 May 2008 12:15:04 GMT http://hdl.handle.net/10199/8 Title: A new species of Discothyrea Roger from Mauritius and a New species of Proceratium Roger from Madagascar (Hymenoptera: Formicidae). <br/> <br/>Authors: Fisher, Brian <br/> <br/>Abstract: The worker of Discothyrea berlita sp. nov. from Mauritius is described. This is the first record of the genus from Mauritius. D. berlita is known from a single locality, Le Pouce, a small sanctuary of native ants on an island overrun with invasive ant species. Proceratium avium is recollected at Le Pouce and is the senior synonym of Proceratium avioide de Andrade (syn. nov.). The practice of manually removing alien plants from native forest plots in Mauritius is not advised for the Le Pouce forest patch because this practice facilitates the establishment of invasive ants, which elim- inate native ants. Proceratium google sp. nov. is described from Madagascar.
