Polyrhachis jerdonii ForelHNS, 1892 (Figs. 2, 6, 10)

Polyrhachis jerdonii ForelHNS, 1892: 17 (footnote). Syntype workers. Type locality: Sri Lanka (Yerbury), MHNG (examined). Polyrhachis jerdoniiHNS: Forel 1893: 17. Description of queen.

Dimensions of syntypes: TL c. 4.94 - 5.29; HL 1.25 - 1.31; HW 1.26 - 1.37; CI 101 - 104; SL 1.22 - 1.25; SI 91 - 97; PW 1.18 - 1.31; MTL 1.31 - 1.40 (3 workers measured).

Additional material examined: Sri Lanka: (as Ceylon), 92 - 128 (no further data) ([[worker]]); (as Ceylon) (no furter data) (leg. G. B. King) ([[worker]], [[queen]]).

Dimensions: TL c. 5.09; HL 1.28; HW 1.29; CI 101; SL 1.22; SI 94; PW 1.22; MTL 1.34 (1 worker measured).

Remarks: Polyrhachis jerdoniiHNS is known only from a few isolated collections from Sri Lanka. It is most similar to P. thailandicaHNS sp. n. , described below. Both have a laterally marginate mesosoma and a weakly indicated meta-notal groove. They differ in the general sculpturation of the body that, in P. jerdoniiHNS, is very finely reticulate-punctate, while it is distinctly more coarsely sculptured in P. thailandicaHNS sp. n.
