Polyrhachis compressicornis appears to be a very rare species that was absent from all recent Sulawesian collections examined. The types in OXUM and a single worker in BMNH are the only specimens I have seen. (Kohout 2008)
Identification
A member of the Polyrhachis relucens species group in the subgenus Myrma

Nomenclature
The following information is derived from Barry Bolton's Online Catalogue of the Ants of the World.
- compressicornis. Polyrhachis compressicornis Smith, F. 1860a: 69 (w.q.) INDONESIA (Sulawesi). Combination in P. (Myrma): Emery, 1925b: 200.
Unless otherwise noted the text for the remainder of this section is reported from the publication that includes the original description.
Description
Type Material
Kohout (2008) - Syntype worker, queen. INDONESIA, SULAWESI, Makassar (A.R. Wallace), Oxford University Museum of Natural History (examined).
The following notes on F. Smith type specimens have been provided by Barry Bolton (details):
One worker syntype and one dealate queen syntype in Oxford University Museum of Natural History. Labelled “Mak.” (= Makassar, Sulawesi), the worker with a Donisthorpe type-label.
Smith did not give a type-locality in the original description of this species. The only specimens in Oxford University Museum of Natural History that met the original description of this species were these two from Makassar, the worker of which was already regarded as a type by Donisthorpe. I can find no reason to doubt his designation.
