The photomontage (right) of a type worker is collated from the images at http://www.antweb.org/specimen.do?name=casent0249889.

The photomontage of the above type worker is colour adjusted to reduce the magenta tint characteristic of all Antweb images. Forel (1909e) gave the colour as entirely black, save for a reddish tint on the head of some largest workers.
