Megalomyrmex weyrauchi

Known only from the type series, nothing is known about the biology of .

Identification
Brandão (1990) - The petiolar shape of M. weyrauchi, in side or front views, clearly separate this species from all other known Megalomyrmex of the Modestus group.

Distribution based on Regional Taxon Lists
Neotropical Region: Brazil, Peru.

Worker
Brandão (1990) - Mandibles smooth with 5-6 teeth; anterior border of clypeus with a median denticle; frontal suture impressed; 3-segmented club; pronotum not tuberculate; promesonotal suture not impressed on thorax dorsum; mesosternum and metasternum without ventral teeth; declivity smooth: anterior slope of petiole straight; ventral face of petiole with anterior denticle; postpetiole without ventral process.

Pilosity: hairs (ca. .lmm) uniformly distributed over the entire body surface, more profuse on the mandibles, head vertex, escape, petiole dorsum, postpetiole, legs and gaster apex.

Color: brown, amost black, opaque.

Type Material
Brandão (1990) - Llama, northern Peru, 2350m, possibly Llama, Cajamarca, Peru (06° 31'S, 79° 08'W). Holotype and 27 paratypes Museu de Zoologia da USP: 5 paratypes Museum of Comparative Zoology, Harvard University. At the MCZ collection I found 5 more specimens, clearly labelled as paratypes by Kempf himself. To the Tucuman specimens I added a label saying “not in the original description, Brandao, 1985”.
