In contrast to the specialized diets expected for most species of Leptogenys, L. pujoli and Leptogenys famelica are, probably, generalist predators, according to field observations (Cavalcanti & Lattke, 2024).

Photo Gallery

  • Cavalcanti & Lattke (2024), Figure 2. Leptogenys pujoli, holotype, DZUP – DZUP549564: (A) body in lateral view; (B) head in full-face view; (C) petiole in dorsal view; (D) mesosoma in lateral view; (E) mesosoma in dorsal view.

Identification

Elongate and mostly punctate head, with longitudinal sulcus between frontal lobes not surpassing posterior edge of compound eyes; protuberant compound eyes; mesosoma without broad metanotal groove, pronotum smooth and shining, rest of mesosoma transversally striate; elongate triangular petiolar node with straight anterodorsal margin from peduncle to summit in lateral view.

Leptogenys pujoli is smaller than Leptogenys famelica, one of the largest species of the genus. Leptogenys pujoli can be distinguished by the longitudinal sulcus not surpassing ocular posterior margin in full-face view, the absence of mesometanotal suture in dorsal view, and the petiolar node with anterodorsal margin mostly straight anterior to spiracle in lateral view, while in L. famelica the longitudinal sulcus surpasses ocular posterior margin, and the petiolar node presents an abrupt angle between the peduncle and the spiracle position.
