This study represents the first species-level taxonomic revision of the genus. Eight species are recognized of which six

are described as new. The new species are E. echinata, E. maschwitzi, E. thrix, E. variegata, E. wittei, and E. zeta.

Euprenolepis antespectans is synonymized with E. procera. Three species are excluded from the genus and transferred to

Paratrechina as new combinations: P. helleri, P. steeli, and P. stigmatica. A morphologically based definition and

diagnosis for the genus and an identification key to the worker caste are provided.10aEuprenolepis10aFormicidae10aFormicinae1 aLa Polla, J., S. uhttps://singaporeants.myspecies.info/node/82702443nas a2200265 4500008004100000245009100041210006900132260000900201300001400210490000700224520167600231653001701907653001501924653001501939653001501954653002101969653001701990653001502007653002802022653001702050100002102067700001802088700002102106856005002127 2010 eng d00aPhylogeny and taxonomy of the Prenolepis genus-group of ants (Hymenoptera: Formicidae)0 aPhylogeny and taxonomy of the Prenolepis genusgroup of ants Hyme c2010 a118 - 1310 v353 aWe investigated the phylogeny and taxonomy of the Prenolepis genus group, a clade of ants we define within the subfamily Formicinae comprising the genera Euprenolepis, Nylanderia, gen. rev., Paraparatrechina, gen. rev. & stat. nov., Paratrechina, Prenolepis and Pseudolasius. We inferred a phylogeny of the Prenolepis genus-group using DNA sequence data from five genes (CAD, EF1αF1, EF1αF2, wingless and COI) sampled from 50 taxa. Based on the results of this phylogeny the taxonomy of the Prenolepis genus-group was re-examined. Paratrechina (broad sense) species segregated into three distinct, robust clades. Paratrechina longicornis represents a distinct lineage, a result consistent with morphological evidence; because this is the type species for the genus, Paratrechina is redefined as a monotypic genus. Two formerly synonymized subgenera, Nylanderia and Paraparatrechina, are raised to generic status in order to provide names for the other two clades. The majority of taxa formerly placed in Paratrechina, 133 species and subspecies, are transferred to Nylanderia, and 28 species and subspecies are transferred to Paraparatrechina. In addition, two species are transferred from Pseudolasius to Paraparatrechina and one species of Pseudolasius is transferred to Nylanderia. A morphological diagnosis for the worker caste of all six genera is provided, with a discussion of the morphological characters used to define each genus. Two genera, Prenolepis and Pseudolasius, were not recovered as monophyletic by the molecular data, and the implications of this result are discussed. A worker-based key to the genera of the Prenolepis genus-group is provided.10aEuprenolepis10aFormicidae10aFormicinae10aNylanderia10aParaparatrechina10aParatrechina10aPrenolepis10aPrenolepis genera-group10aPseudolasius1 aLa Polla, J., S.1 aBrady, S., G.1 aShattuck, S., O. uhttps://singaporeants.myspecies.info/node/828
