Diagnosis – Eye placed slightly anterad of cephalic mid-length, length occupying close to one-third of lateral cephalic margin – Scape not reaching posterior cephalic margin when pulled posteriorly – Funicular segments broader than long – Malar carina absent – Mandible triangular, relatively short and robust – Mandible lacking lateral sulcus – Mandibular apex in dorsal view blunt – Teeth along masticatory margin short and of similar size – Lateral hypostomal process (tooth) with tip directed ventrally, not anteriorly or anterolaterally – Humeral carina absent – Propodeal spiracle slit-shaped, almost vertical – Metapleural gland opening facing laterally, dorsally partially covered by low lobe, posteriorly bound by flange with convex lip – Petiole sessile with blunt anterolateral projection – Helcium with narrow transverse rugulose strip between pretergite and constriction at anteroventral face of tergite III – Prora protrudes anteriorly as brief, anteriorly projecting, bluntly pointed lobe with convex ventral face bordered by lip along lateral margin – Cinctus strongly marked – Stridulitrum absent – Epipygium and hypopygium lacking spine-like setae or stout hairs – Epipygium convex in cross-section, not posteromedially flattened – Meso- and metatibial apex each with two spurs, one long and pectinate, one short and simple – Meso- and metatibial apices lacking spine-like setae – Tarsal setae (except on probasitarsus) elongate and of flexuous appearance, particularly on penultimate tarsomere – Claws simple with small arolium – Head, mesosoma, and petiole with longitudinal, parallel, uniform costulae. Etymology The genus name is derived from the Brazilian name for black-water flooded forests in the Amazon region, Igapó . The suffix “- ponera ” is derived from the Greek word “poneros” for “wretched”, “wicked”, “useless”. It is commonly used in generic epithets of the subfamily Ponerinae . It is a non-Latinized neologism and thus invariant.
