Heteroponera ecarinata

Identification
Characterized in the H. ecarinata species complex by relatively heavy sculpturation, dark blackish-brown color, with dark reddish-brown legs and antennae, and distinguished from the somewhat similar Heteroponera pendergrasti by differences in sculpturation (particularly of the frons and second gastral tergite), coloration and structure of petiolar node. Fore-coxae, propodeal declivity and posterior surface of node superficially microsculptured; propodeal declivity laterally distinctly, but not strongly, sculpturally bordered: the posterolateral edges in profile more-or-less regular and even, not serrate as a result of minutely extended cuticular points along the sculptural border. Most specimens apart from the Bellenden Ker series have the petiolar summit weakly pointed posterodorsally, and some appear not to be fully colored, possibly sub-callow. The gaster in these is lighter brown than the remaining body (and also the mesosoma in two cases). The propodeal declivity is unsculptured in most specimens, but microsculptured in several.
