Gesomyrmex luzonensus ^HNS (Wheeler).

Dimorphomyrmex luzonensis Wheeler ^HNS, 1916, Proceedings of the New England Zoological Club, 6:16-18. fig. 4, [[queen]].

Gesomyrmex luzonensis var. chapmani Wheeler ^HNS, 1930, Psyche, 37:35-40, fig. 1, all castes. (New synonymy.)

Female types compare very well, except that in G. chapmani ^HNS very slight fading is apparent but insignificant as a point of differentiation.
