Description
Worker
Mandibles smooth; anterior border of clypeus with median denticle; flat median area of clypeus limited by carinae (better seen at 80x); 3-segmented antenna! club; 10-12 ocular facets at eye largest diameter; occipital margin not raised; dorsal profile of promesonotum continuous, promesonotum suture impressed laterally; meso sternum and metasternum without acrotergites; dorsal face and declivity of propodeum meeting in a gentle angle; declivity with 3-4 concentric rugosities over the foramen; petiole with an teroventral denticle; petiolar node, in frontal view, acuminate; postpetiole ventral process globose.
Pilosity: 6 long erect hairs (more than .2mm) at pronotum, 4-6 at the apex of petiole and post petiole, 15-16 at the gaster segments and anterior face of fore coxae. Small subdecumbent hairs (circa .lmm) uniformly distributed over the body surface. Color: uniform bright light-yellow.
Queen
Clypeal carinae only at the posterior region of clypeus; ocelli equally developed; parapsidal sutures impressed on mesonotum; scutum and scutellum with 2 parallel rows of long hairs; ventral process of postpetiole acuminate.
Type Material
3 Km SW Bucay, prov. Guayas, Ecuador (02°10'S, 79° 06'W). Holotype (worker) and 2 paratypes (workers) at Museum of Comparative Zoology, Harvard Univ.; 1 paratype (worker) at British Museum of Natural History; 2 paratypes (queen and workers) at Museu de Zoologia da USP.
Etymology
Caete means forest in Tupi.
