Kohout (2006) - A member of the Polyrhachis cryptoceroides species group. Similar to Polyrhachis thailandica. Both have a laterally marginate mesosoma and a weakly indicated metanotal groove. They differ in the general sculpturation of the body that, in P. jerdonii, is very finely reticulate-punctate, while it is distinctly more coarsely sculptured in P. thailandica.
