Habitat/Ecology. This species is associated mainly with both mature and young secondary forests, including native-dominated, abandoned plantation, and waste woodland forests, often fragments in urban or semi-urban settings. Sometimes the ants have been found on low vegetation and foliage in urban parklands. The species is considered arboreal and individuals are often found on tree trunks or branches, or foliage in general. Nests have been found under bark of living trees or large fallen logs.

Remarks. Platythyrea parallela is known to exhibit broad (body) size variation among both sympatric and allopatric populations. Other variable traits include shape and size of propodeal angles, shape of the petiolar node (specifically that of the posterodorsal margin), and body sculpture.At the point of writing, all size and morphological variants observed from local material have thus been treated as conspecific, pending future more refined analyses to distinguish between different species of this potential species complex.
