Description

Worker

Major. Length 14 mm. (without mandibles); length of mandibles 3.6 mm.

Minor. Length 10 mm.

Whole of head and thorax bright mahogany-red, legs duller, mandibles and scapes shaded with brown, gaster black.

Pilosity as in forficata; pubescence almost nil.

Mandibles somewhat longer and slenderer and the outer borders less concave than in forficata. The scape reaches slightly further beyond the occipital border. 'l'he occipital angles more rounded.

Whole thorax narrower, the pronotum narrower in front; the base of epinotum pointed in front and the angle between the two faces more pronounced. The stalk of the first node is longer and the node more cubic in profile. There is a distinct longitudinal impression down the centre of pronotum and epinotum.

Whole body shining. Head very clearly and regularly striate, the striae diverging slightly behind the eyes. There is no trace of rugosity. The striation is more clean-cut than in sanguinea and there is no ground-reticulation between the striae as in that species. There is a microscopical reticulation between the eyes and frontal carinae.

The whole striation of thorax is of this clean-cut description; on the pronotum it is transversely arched and on the rest transverse. The first node is superficially transversely striate and has a few indistinct punctures. The second node and gaster are microscopically reticulate.
