Polyrhachis compressicornis

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

Distribution based on Regional Taxon Lists
Indo-Australian Region: Indonesia, Sulawesi.

Nomenclature

 *  compressicornis. Polyrhachis compressicornis Smith, F. 1860a: 69 (w.q.) INDONESIA (Sulawesi). Combination in P. (Myrma): Emery, 1925b: 200.

Type Material
Kohout (2008) - Syntype worker, queen. INDONESIA, SULAWESI, Makassar (A.R. Wallace), (examined).

One worker syntype and one dealate queen syntype in. 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 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.
