Abstract: Two new species of Leptogenys based on the worker caste are described under the names Leptogenys lattkei sp. nov. and Leptogenys transitionis sp. nov. The ergatogyne of Leptogenys transitionis also reported here is the first of its kind in Leptogenys, characterised by a highly enlarged gaster, three prominent ocelli and the absence of wing sclerites. The ergatogyne of L. transitionis is intermediate between that of L. ergatogyna, with well-developed wing-base sclerites and ocelli, and the more usual ergatoid condition characterised by degenerate ocelli.
