Bharti, 2001

The type material was collected from a soil nest.


Bharti (2001) - P. terraceensis is somewhat allied to Pheidole malinsii; but can be easily separated as; propodeum transversely rugose and punctate in P. terraceensis; but smooth and shining in malinsii; petiole without spine on appendage in P. terraceensis; with spine in malinsii: gaster finely punctate all over in R. terraceensis; longitudinally striate only on basal half in malinsii,· head punctured, reticulate in minor of P. terraceensis; but smooth in malinsii: scape extending beyond the top of head by more than half of its length in P. terraccensis (minor): but by one fourth in malinsii.
