Specimen Labels

Surprisingly, this ant is known from one series of five workers collected in the old established Perth suburb of Mosman Park, and (after completion of this study) a single worker from Rottnest Island, Western Australia.


Heterick (2001) - A member of the bicorne group. The taxon closely resembles Chelaner rufoniger, which also occurs in the Perth region, and may simply represent aberrant individuals (e.g. nanitic or callow minor workers) of this fairly common species. All individuals of C. pubescens, however, lack stout erect or suberect setae on the alitrunk, and are much paler than any C. rufoniger minor worker I have seen.

Heterick (2009) - Workers are very similar to minor workers within polymorphic populations of Chelaner rufoniger.

Holotype. HML; 1.39; HL 0.53; HW 0.48; Cel 91; SL 0.36; SI 74; PW 0.30. Other. HML 1.35-1.51; HL 0.49-0.57; HW 0.43-0.52; Cei 88-96; SL 0.34--0.38; SI 72-79; PW 0.25-0.28 (4 measured, including alcohol specimens).

As for light coloured minor workers of Chelaner rufoniger but with the following apomorphies.

Alitrunk. Promesonotal sculpture present in form of uniform microreticulation with few mesopleural striolae; dorsal promesonotal face convex anteriad, otherwise flattened; erect and suberect setae absent on promesonotum; setulae appressed. Propodeal angle present; length ratio of dorsal face to declivitous face near 2:1 to near 4:3; declivitous face of propodeum flat. Erect and suberect propodeal setae absent or very sparse; propodeal setulae appressed.

Petiole and postpetiole. Petiolar node conical, sharply tapered; sculpture present in form of microreticulation. Ratio of greatest node breadth (viewed from front) to greatest node width (viewed in profile) near 4:3. Height ratio of petiole to postpetiole near 1:1; height-length ratio of postpetiole near 2:1 to near 4:3.

Gaster. Pilosity of first gastral tergite consisting mainly of decumbent and subdecumbent setulae.

General characters. Colour of body and appendages tawny yellow, head darker. Worker caste monomorphic.

Type Material
