Southern Mexico (type locality) to Costa Rica. Costa Rica: Cordillera de Talamanca to Cordillera de Tilarán at mid-elevation.
Face densely foveolate-granular, matte; dorsum of postpetiole foveate-granular like petiolar dorsum; first gastral tergite shagreened with microreticulum, not smooth and shining; in face view posterolateral margins of head with strong triangular projections.
This species is a montane specialist, occurring in cloud forest habitats. It is common in the Monteverde area, from 1300m on the Pacific side, across the divide, and down to 900m on the Atlantic side. I also have records from Fila Cruces near San Vito, and the 1500m site (Finca Murillo) on the Barva transect. Raiding columns are normally seen during the day, and it may be a primarily diurnal forager.
