Nomenclature

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

  • dolomedes. Polyrhachis dolomedes Smith, F. 1863: 14 (w.q.) INDONESIA (Seram I.). Combination in P. (Myrmatopa): Donisthorpe, 1932c: 469. Senior synonym of amboinae: Kohout, 2012: 35.
  • gracilior. Polyrhachis (Myrmatopa) schang var. gracilior Karavaiev, 1927e: 11 (w.q.m.) INDONESIA (Ambon I.). [Junior primary homonym of gracilior Forel, above.] Replacement name: amboinae Santschi, 1928h: 139.
  • amboinae. Polyrhachis (Myrmatopa) schang var. amboinae Santschi, 1928h: 139. Replacement name for gracilior Karavaiev, 1927e: 11. [Junior primary homonym of gracilior Forel, 1893c: 25.] Junior synonym of dolomedes: Kohout, 2012: 35.

Polyrhachis dolomedes type material.

Note: Barry Bolton supplied Kohout (2012) with a copy of his unpublished ‘Catalogue of F. Smith type-material from UM, Oxford’ which contains the following notes on the syntype material of P. dolomedes: 'Syntypes 1 worker and 1 queen in UM, Oxford. One further syntype (worker) in BMNH. The UM Oxford specimens bear a Donisthorpe type-label and the BMNH specimen a ‘compared with type’ label of Donisthorpe. However, if the writing on the underside of the stage cards is consulted it becomes obvious that all three specimens were originally mounted together and that the card has been divided at a later date. The underside of the stage card of the BMNH specimen has ‘P. /’ (part of the ‘D’) and ‘Ceram’. The Oxford specimens have ‘Dolomedes’ (with part of the ‘D’ missing). The two cards fit together perfectly to read ‘P. Dolomedes. Ceram’' (Bolton unpublished data, cited by Kohout, 2012).

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

One worker syntype and one queen syntype in Oxford University Museum of Natural History (on a single piece of card); one worker syntype in The Natural History Museum. The Oxford University Museum of Natural History specimens have a Donisthorpe type-label and the The Natural History Museum specimen has a Donisthorpe “compared with type” label. However, when the writing on the underside of the stage cards is consulted, it becomes obvious that all three were originally mounted together and that the card has been divided at a later date.

The underside of the stage card of the The Natural History Museum specimen has, “P”, plus part of a letter “D,” and “Ceram.” The Oxford University Museum of Natural History card has “Dolomedes” (with part of the “D” missing). The two cards fit together perfectly to read, “P, Dolomedes. Ceram” (= Seram I.).

Polyrhachis schang gracilior type material.

  • Syntype workers, queens, males and ergatogynes from Ambon I., Indonesia, Leitimor, Hito (V. Karavaiev # 2501, 2503) (IZAS, Queensland Museum) (examined by Kohout, 2012).

The following notes on V.A. Karavaiev type specimens have been provided by Martynov & Radchenko (2016) based on material held in the Institute of Zoology, Ukrainian Academy of Science:

Type locality(-ies): “Amboina (Leitimor und Hito), 20.II.1913 (Nr. 2501, 2503), ww, geflüg. qq, 1 Königin, mm und 2 Ergatogynen”.

Original Karawajew label(-s): “Polyrhachis (Myrmatopa) / schang For. v. amboinae Sant. / (n. nom.). Amboina, Karavaev, / 2502, 2503, 2504”.

Material: SYNTYPES, 4 w, 2 q, 2 m (newly mounted, IN 314/6/1), 142 w, 10 q, 13 m (in alcohol, IN 314/BAMS1/Karaw7–10).

Notes. In his original description Karawajew (1927a) provided the collection numbers 2501 and 2503 for the type series of this taxon, while in the single vial with alcohol material in NMNH NASU there are original Karawajew labels with collection numbers 2502, 2503 and 2504. We investigated several tens of workers, queens and males from this vial and confirm their conspecificity. We may only suppose that Karawajew did not provide all the collection numbers when describing this taxon, and we consider all the material from NMNH NASU as syntypes.
