Costa Rica: mid-elevation Atlantic slope and Cordillera de Tilaran.
This species inhabits montane moist to wet forest. Project ALAS collected it at the 1070m site on the Barva Transect in Braulio Carrillo National Park. It was collected in Malaise traps, flight intercept traps, Winkler samples of forest floor leaf litter, and as foragers hand collected in the refuge clearing. One collection is also known from Monteverde. Longino collected it in the lower Bajo del Tigre forest, a moist forest area just below the continental divide on the upper Pacific slope. A nest was found beneath a stone.
The elongate head of the major is a very distinctive feature of this species, relative to variegata and other similar species. It keys to aciculata in Wilson (2003) but the scapes are shorter and it is generally smaller.

Collected most commonly using these methods or in the following microhabitats: 3 times search, 15 times flight intercept trap, 5 times Mini Winkler, 1 times baiting, 1 times Malaise
