Identification
Bharti (2001) - The species P. duneraensis is somewhat allied to Pheidole malinsii and Pheidole terraceensis; but can be easily separated from both. From P. malinsii as; propodeum smooth and shining in malinsii; densely punctured in P. duneraensis; petiole appendage with a spine in malinsii; without spine in duneraensis; gaster longitudinally striate in basal half in malinsii; but densely punctured in basal half and finely punctured in rest of it in duneraensis. P. duneraensis can also be separated from P. terraceensis as; clypeal incision ending into acute teeth in terraceensis; blunt teeth in duneraensis; propodeal spines long in terraceensis; short in duneraensis; alitrunk rugulose along with fine punctures in terraceensis; but densely punctured without rugae in duneraensis. Both species differ remarkably in measurement indices, discussed in text, apart from other differences.
