Megalomyrmex glaesarius Kempf, 1970

This species was known only from the type specimens from Llama, Cajamarca, Peru and from one sample collected 94 Km southwest of Cuencas, Nieves, Napo, Peru. I recently studied the first Colombian sample: two workers ( IHVL) collected by F. Escobar at 1000 m in Tajadas, Barbacoa, Nariño, Colombia in May 1, 1994. These workers have the gaster with the same color as the rest of the body, while other samples of this species have the gaster decidely darker, almost shiny black, including the males from lago Agrio (see Brandão, 1990), not included in M. glaesarius for biogeographic reasons. However, in all other characters, the Colombian sample agrees with the diagnosis for M. glaesarius , extending further north the known distribution of this species. Nothing is known on the biology of M. glaesarius .
