The higher classification of the ant subfamily Leptanillinae (Hymenoptera: Formicidae)

Abstract. Until now the ant subfamily Leptanillinae has been closely linked with the army ant subfamilies Dorylinae and Ecitoninae, but on relatively tenuous evidence. The current phylogenetic study strongly indicates that this view is incorrect and that the leptanillines really constitute the sister-group of subfamily Ponerinae, and are at a consider- ably greater taxonomic distance from the Army Ant subfamilies. Three tribes are now recognized within the Leptanillinae (Leptanillini; Anomalornyrmini, new tribe; and Apomyrmini, transferred here from Ponerinae: Arnblyoponini), containing a total of eight genera with fewer than fifty species in all. The subfamily and its component tribes are diagnosed and discussed here, and a key to genera provided. New taxa described include Anomalomyrma Taylor gen.n., type-species A. taylori Bolton sp.n. and Protanilla Taylor gen.n., type-species P. rafflesi Taylor sp.n.
