Identification

Kohout (2008) - There are two members of the subgenus Hedomyrma present in Sulawesi:

  • Distinctly bicoloured; head and tarsi black with mesosoma, petiole and femora light reddish-brown; gaster and tibiae distinctly darker . . . . . Polyrhachis fervens

Distribution

The distribution of P. fervens extends from eastern Indonesia (Halmahera, Seram and Ambon Is) to New Guinea and south to Cape York Peninsula, Queensland. It is known from lowland rainforests at Bamaga near the tip of Cape York Peninsula and at Iron Range.

Distribution based on Regional Taxon Lists

Nomenclature

The following information is derived from Barry Bolton's New General Catalogue, a catalogue of the world's ants.

  • fervens. Polyrhachis fervens Smith, F. 1860b: 101, pl. 1, fig. 26 (w.) INDONESIA (Ambon I.). Combination in P. (Dolichorhachis): Emery, 1925b: 189; in P. (Hedomyrma): Dorow, 1995: 27; Bolton, 1995b: 348. Senior synonym of indocilis, kershawi, valerus: Kohout, 1988c: 434.
  • valerus. Polyrhachis valerus Smith, F. 1861b: 40, pl. 1, fig. 10 (w.) INDONESIA (Sulawesi). Combination in P. (Hedomyrma): Emery, 1925b: 190. Junior synonym of fervens: Kohout, 1988c: 434.
  • bicolor. Polyrhachis (Hedomyrma) bicolor Karavaiev, 1927e: 21, fig. 11 (w.) INDONESIA (Ambon I.). [Junior primary homonym of bicolor Smith, above.] Replacement name: indocilis Santschi, 1928h: 139.
  • indocilis. Polyrhachis (Hedomyrma) indocilis Santschi, 1928h: 139. Replacement name for bicolor Karavaiev, 1927e: 21. [Junior primary homonym of bicolor Smith, F. 1858b: 65.] Junior synonym of fervens: Kohout, 1988c: 434.
  • kershawi. Polyrhachis (Hedomyrma) kershawi Clark, 1930c: 12, fig. 1 (w.) AUSTRALIA. Junior synonym of fervens: Kohout, 1988a: 434.

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) - Holotype worker. INDONESIA, Ambon I. (A. R. Wallace), Oxford University Museum of Natural History(examined).

  • Polyrhachis fervens: Syntype, worker(s), Amboyna, Indonesia.
  • Polyrhachis (Hedomyrma) kershawi Clark, 1930: Syntype, worker(s), Claudie River, Queensland, Australia, Australian Museum.
  • Polyrhachis (Hedomyrma) kershawi Clark, 1930: Syntype, worker(s), Claudie River, Queensland, Australia, Museum Victoria, Melbourne.

Kohout (1988) - Prof. Radchenko of the Zoological Institute, Kiev, informs me that the unique holotype of Karawajew's homonym P. bicolor cannot be found in the Karawajew collection, and is presumed lost. However, the original description and illustration are sufficient to establish its synonymy beyond reasonable doubt.

The following notes on F. Smith type specimens have been provided by Barry Bolton (details):

Polyrhachis fervens

Holotype worker in Oxford University Museum of Natural History. Labelled “Amb.” (= Ambon I.) and with a Donisthorpe type-label.

Polyrhachis valerus

The specimen in Oxford University Museum of Natural History labelled as type by Donisthorpe matches the rather poor description well, but the data label upon it reads “Men.” (= Manado, Sulawesi). The type-loclaity recorded by Smith is “Celebes, Tondano.”
