Nothing is known about the biology of Megalomyrmex myops.

Identification

Brandão (1990) - At the original description Santschi (1925) stated that the propodeal declivity bears fine longitudinal stria. This may refer to the faint lateral carinae, as the center of the declivity is totally smooth. Santschi noticed (1936) the variation in number of denticles at the mandibles blades in non-type specimens. Apart this observation and the presence of small faint denticles at the clypeus anterior border in specimens from S. Paulo localities, all specimens are identical in terms of the diagnosis stated above.

Description

Worker

Brandão (1990) - Smooth mandibles with dental formula 3+ (3-5); median area of clypeus with longitudinal rugosities and anterior border round with median denticle; 6-7 ocular facets at compound eyes largest diameter; frontal suture not impressed; occipital margin not raised; promesonotal suture not impressed dorsally: dorsal face and declivity of propodeum meeting in gentle angles, declivity with faint lateral carina but no concentric rugosities; epipetiolar carina incomplete dorsally: ventral face of petiole with longitudinal flange including the anterior denticle: postpetiolar node globose; ventral face of postpetiole without process.

Pilosity: long erect hairs (ca. .15mm) at body dorsum, smaller subdecumbent hairs at antennae, mandibles, legs and ventral face of gaster.

Color: bright deep-yellow with darker gaster in some specimens.

Type Material

Rio Negro, Parana. Brasil. (26°06'S, 49°48'W). Lectotype designation: Lectotype at Naturhistorisches Museum, Basel: 1 paralectotype (not examined) at the same collection.
