Nomenclature

 *  iheringi. Megalomyrmex iheringi Forel, 1911c: 304 (w.) BRAZIL. Borgmeier, 1930: 33 (q.). See also: Brandão, 1990: 424.

Worker
Brandão (1990) - Mandibles smooth; clypeus not carinate, with anterior margin round, not denticulate; frontal suture not impressed: club with 3 segments; occipital margin raised but not visible in frontal view; dorsal pronotal profile continuous: promesonotal suture impressed dorsally; mesosternum and metasternum without ventral processes: dorsal face and declivity of propodeum meeting laterally in an obtuse angle, dorsal face faintly impressed medially; declivity without rugosities: ventral face of petiole with anterior denticle; postpetiole without ventral process.

Pilosity: small suberect hairs (ca .1 mm) uniformly covering antennae, head capsule, mandibles, legs, anterior face of petiole and postpetiole nodes and gaster. Long hairs (ca. .2mm) at thorax dorsum and apex of petiole and postpetiole nodes.

Color: uniformly bright reddish-brown.

Borgmeier (1930) pointed out some inaccuracies in Forel's original description, especially as to the raised margin of vertex. Furthermore, I observed in all studied workers an anterior denticle on the ventral face of the petiole, contrary to Forel's statements.
