Key to Australian Genera of Dorylinae

AntWiki: The Ants --- Online

This key to Australian genera of the subfamily Dorylinae is based on Borowiec (2016) [1]


  • Last visible abdominal tergite, the pygidium, not armed with numerous modified setae, at most with only one or two pairs of thick setae or cuticular projections (Figures A, B). Propodeal lobes short or absent. Propodeal spiracles positioned high above mid-height of the propodeum or, more rarely, placed low => Aenictus
  • Pygidium armed with numerous specialized setae that are peg-like or spiniform, much thicker than surrounding fine hairs (Fig. C); setae more than four in number, often more numerous. If pygidium small or with few specialized setae, then propodeal lobes conspicuous. Propodeal spiracles almost always positioned relatively low, in lateral view placed at least as close to ventral margin as to dorsal surface of the sclerite => 2

  • At least anterior dorsolateral portions of abdominal segment II (petiole) marginate (Figure B) and often entire length of petiolar tergite with pronounced margins (Figure A). Hind coxa usually with posterior flange drawn into a vertical, opaque or semi-translucent lamella (Figure D). Metatibial gland pore plate usually in a depression or invagination of the cuticle, appearing as a slit (Figure F) or, more rarely, a circular opening (Figure G) or inconspicuous => Lioponera
  • No segment of body conspicuously dorsolaterally marginate although lateral crest immediately above abdominal segment II (petiolar) spiracle may be present (Figure C). If abdominal segment II appearing marginate, hind coxae without posterior vertical lamella (Figure E). Metatibial gland pore plate not in a depression, either an oval whitish patch (Figure H), or not discernable (Figure I) => 3

  • Gaster with the junctions between the last four segments distinct constrictions so that in profile their upper surfaces form a series of convexities. In lateral view promesopleural suture either completely or partially fused, never a curved cut in the cuticular surface approaching dorsolateral margins of promesonotum (Figs. A, B) => Zasphinctus
  • Gaster with the junctions between the last four segments smooth so that in profile their upper surfaces form a smooth outline. In lateral view promesopleural suture present as a deep cut in the cuticle, often curved below the dorsolateral margins of mesosoma and often with short pubescence lining the inside of the suture (Figs. C, D) => Ooceraea
