Dolichoderus patens

Rohe 1991 polydomous; multi-chambered carton nests on the undersurface of leaves, trophobiotic partners kept inside and outs ide these nest-pavilions; alarm communication by drumming of gaster against the substrate.

Identification
Dill (2002) - A member of the Dolichoderus sulcaticeps species group. Typically, D. patens is yellow to reddish-brown and shining, though more matt and less shining than Dolichoderus sulcaticeps. Head and alitrunk are, in addition to the fine sculpturing that is very finely reticulate to shagreened, irregularly wrinkled with scattered shallow pits; the sides of the propodeum are coarsely areolate-rugose. The gaster is sparsely to densely pubescent. D. patens patens, patens pubiventris, Dolichoderus siggii, and Dolichoderus crawleyi form a complex of species that are difficult to separate clearly. Regarding the surface sculpturing, there are clinal transitions to siggii as well as to crawleyi. Aside from the body size, crawleyi can mainly be distinguished from patens pubiventris by its coloration, and from siggii by the lesser heights of the petiolus scale. It seems to be possible that a more thorough examination will lead to the synonymization of both species with patens.
