Worker major Length 11-16 mm. Head 5 mm wide and 5 mm long, without the mandibles. Mandibles with 7-8 teeth, with weakly convex outer edge, glossy, extremely finely and irregularly punctate reticulate; in addition scattered coarse punctations, towards the outer edge coarse long strips and everywhere rather ample covering of upstanding hair. Clypeus at the anterior and at the posterior with a trace of a keel in the middle, in front forming a short trapezoidal lobe whose anterior edge is very shallow concave (almost straight). Head rounded trapeze shape, posterior wider than anterior, in addition where, near the mandibles attachment more strongly narrowing, posterior strongly concave with rather convex sides. The scape protrudes over the posterior head for about 1/4 of its length. Eyes rather flat, almost round. Frontal ridges S shaped, moderately diverging. Frontal area triangular, indistinct. Promesonotum moderately convex; promesonotal suture deeply imprinted. Basal surface of the metanotum (= propodeum) standing rather deeper than the mesonotum, strongly transversely convex, but its length is not quite horizontal, joining with a similar length sloping surface in a rounded curve. Node narrow, but very large, almost in the shape of a knot, below especially strongly thickened, above (seen from the side)thinned down cone shaped, but therefore very blunt.Tibias cylindrical without barbs. Glossy, to softly shining. Head thickly and finely reticulate, the rest, also the limbs more finely transversely striate; thorax reticulate striate. Moreover regular scattered not coarse and rather shallow punctations. On the gaster the punctations are not so deep; on the limbs they are numerous and on the clypeus and cheeks coarser, in parts elongated. Very ample, brownish yellow, covering of upstanding hair, sharp but not long. The flat-lying covering of hair is extremely scattered and inconspicuous. The tibias are especially thickly and richly bristled. Black; tarses, mandibles and antennae brown. Sometimes a much weaker dark blue metallic shimmer which however seems to fade away as I saw it clearly in the beginning, but then no more.
Worker minor. Clypeus distinctly keeled with an arc shaped anterior border. Eyes convex. Head somewhat longer than wide, rectangular from the front corners to behind the eyes, with parallel sides, behind the eyes up to the articulation the head becomes narrower with convex sides without forming a neck, so that from one eye to the other the posterior margin forms a strong convexity. Promesonotum convexity is weaker than with the major worker. Node rounded, knot shaped, the base thicker than high. Otherwise like the worker major.
Station 114, Buckland Hill; Stat. 131 Serpentine.
Very closely related to intrepidus Kirby especially the subspecies bellicosus Forel but broader and colored differently. Perhaps only a sub species.
