Specimen Labels

Chapman (1963): Workers and wingless females were taken from forays of Myrmicaria on the Cuernos de Negros at 1,500 to 4,000 feet altitude for many years. It was not until September 12, 1948, that I found a colony. It was in a dead frond of a tree fern. The fern trunk was partly surrounded by a mound nest of Myrmicaria. I took workers from the foray of this species began to look for the Polyrhachis nest again and found it in the fern frond. Both workers and females closely resemble Myrmicaria in color very closely. This is, the only nest I ever found.


A member of the Polyrhachis parabiotica species group.

The body colour is orange-red on Negros while it is red on Luzon.
