Formicidae, Hymenoptera, Insecta, Arthropoda, Animalia
Bolivia, Colombia, Costa Rica, Panama (Brown 1958, Lattke 1995). Costa Rica: potentially throughout.
Promesonotal suture very faintly impressed, not breaking sculpture; scapes surpass margin of vertex when laid back; mandibles distinctly triangular, basal margin flat; propodeum with small peg-like teeth; anterior pronotum covered by a broad band of transversely arching costulae; posterior lobe of subpetiolar process well developed, square-cut to acute, and subequal in size to anterior tooth.
This species is rare or has habits that make it difficult to observe. I have seen the following collections:
Alajuela: Casa Eladio, Rio Penas Blancas, 10¡19'N, 84¡43'W, 800m (J. Longino), montane wet forest, nest in dead wood.
Guanacaste: Estacion Pitilla, Guanacaste Cons. Area, 10¡59'N, 85¡26'W, 700m (J. Longino), montane wet forest, collected from two different Winkler samples of sifted leaf litter from forest floor. One of the specimens a dealate queen.
Heredia: La Selva Biological Station, 10¡26'N, 84¡1'W, 50m (ALAS), alate queen in malaise trap.
Puntarenas: 6km SW Monteverde, 10¡16'N, 84¡50'W, 900m (J. Longino). Small, isolated patch of moist forest in ravine, surrounded by degraded pastures. Understory disturbed by cattle. Collected in Winkler sample of sifted leaf litter.
Puntarenas: Wilson Botanical Garden, 4km S San Vito, 8¡47'N, 82¡58'W, 1200m (J. Longino), montane wet forest, collected in Winkler sample of sifted leaf litter from forest floor.
