Description

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”.
