Viehmeyer 1916: 141 - Malay Peninsula: beneath the bark of a branch of a dead tree; Le Pelley 1943: 79 - Philippines and Java: trophobiosis with Planococcus lilacinus (Cockerell) (Pseudococciclae); Manmohini Devi et al. 1987: 104 - India: trophobiosis with the aphids, Greenidea formosana heeri Raychaudhuri and Aphis gossypii Glover. Dill 2002 - often in trophobiotic associations with different pseudococcids, aphids (e. g. Pseudoregma sp.) and membracids [e.g. Ebhul varius (Walker)]; polygynous, nest in hollow, dead tree branch.

Identification

Dill (2002) - Morphologically near Dolichoderus thoracicus except for posterior margin of ascending dorsal face of propodeum more sharply edged and, in profile, distinctly overhanging the concavely curved declivity. Regarding this character, the affinis workers somewhat resemble those of Dolichoderus pilinomas of the Dolichoderus cuspidatus group. However, the propodeum of the latter rises distinctly higher.
