Taxonomic Notes
Because the conditions of Article 23.9.1 of ICZN (4th edition, 1999) do not appear to have been satisfied, the previously overlooked nominata Smith, F. 1871a: 323, the first proposed replacement name for the junior homonym simillima Smith, F. 1860b: 105, takes priority over churchilli, majuscula, poultoni, and testacea (B.Bolton note, 17.v.2016).

Worker
Shattuck (2008) - for the synonomized P. majuscula: (n=5) CI 78–81; HL 0.61–0.69; HW 0.50–0.56; ML 0.74–0.79; PetL 0.18–0.20; PetW 0.25–0.29; PI 138–155; SI 61–66; SL 0.32–0.34; T1W 0.36–0.43.

Anterolateral corners of head, near mandibular insertions, generally rounded and lacking a tooth but occasionally with a very small, obscure tooth on each side. Dorsal mesosomal sculpturing reduced to minor irregularities consisting of fine punctuations. Lateral mesosomal sculpturing weakly developed on pronotum and anterior and ventral region of mesopleuron, dorsal region of mesopleuron and majority of propodeum smooth. Fenestra present within subpetiolar process. Colour pale yellow, queens sometimes yellow-brown.

Type Material


Ponera simillima

In the original description Smith states that the type-specimens are workers, but only queens of this taxon are present in his collection. It is assumed here that he miswrote the caste in the description, though this can not be proved; the four queens of the species are regarded here as the syntypes, though perhaps incorrectly.

One dealate queen syntype in. Labelled “Dor. 20” (= Dory I., New Guinea).

Three dealate queen syntypes in. Labelled “Dor.” One specimen has a Donisthorpe type-label and a det. label “P. poultoni,” Donisthorpe’s replacement name for the preoccupied simillima. One of the others has a Donisthorpe det. label from 1931, “simillima.”
