Longino, J. T., 2007:
Azteca jelskii Emery 1893:338. Syntype workers: French Guiana , Cayenne ( Jelski ) [ MCSN ] (examined).
Azteca tonduzi var. columbica Forel 1912:51. Syntype workers: Colombia , Ouriheka [=Orihueca] near Rio Frio ( Forel ) [ MHNG ] (examined). NEW SYNONYMY
Range. Northern South America to Peru, Bolivia.
Biology. The types of columbica were collected on a live tree that also contained a nest of Dolichoderus decollatus (Forel 1912). Doug Yu's Manu collection was from a carton nest on Inga stipulacea . In Venezuela I collected a nest in a dead vine stem, and a polygynous nest with many dealate queens in a dead Cecropia branch.
Comments. Azteca jelskii is a South American version of A tonduzi . The only difference is that the scape and tibiae of A jelskii lack erect setae. The scape and tibiae of A tonduzi have an inconspicuous but distinct series of short erect setae. There is variation in queen head size in South America. A queen from Venezuela is smaller than queens of A tonduzi (HLA 1.01mm versus 1.10-1.16mm, respectively); two queens, one from Peru and one from Bolivia are similar in size to A. tonduzi queens (HLA 1.16-1.17mm).
