Natural History
The type specimens of this species are from Apaicn, Volcan Iraz. Borgmeier (1955) examined a second collection by Schmidt from San Jos.
I know this species from one collection. I found a column of workers beneath a stone at the edge of a gravel road. The habitat was an open pasture area that had been recently burned. The locality was the San Luis Valley, on the Pacific slope just below Monteverde, at 1050m elevation. The collection was made in the middle of a hot day. The smallest workers of this species were remarkably tiny, about the size of small Diplorhoptrum Solenopsis.
