Diagnosis

With a unique morphometric profile. Minor worker: the most distinctive character is the postpetiole, which is much longer than wide in dorsal view and flask-shaped. The postpetiole shape combined with large size and foveolate face should distinguish it from all other species. Major worker: head subrectangular versus with sides more convex and posterior margin more cordate (bulliceps, galba, gigasHNS, hirsutaHNS, huacana); vertex lobes foveolate overlain by reticulate rugulae versus with arcing subparallel rugae ( arciferaHNS, rheaHNS) or relatively smooth and shining (astur, auropilosaHNS, bergiHNS, geraesensisHNS, huacana, oxyopsHNS, trageriHNS); base of scape terete versus flattened ( claviscapaHNS); propodeal spines long versus short (tigris, trageriHNS); first gastral tergite shallowly foveolate anteriorly, grading to smooth and shining posteriorly, versus more uniformly foveolate, opaque ( voraxHNS).

Biology

This species occurs in lowland to mid-elevation wet forest. Minor workers have been collected at baits. One major worker has been collected, at a bait along with minor workers.

Etymology

The name is in reference to the elongate, flask-shaped postpetiole.
