Worker
TL 2.9 - 3.0, HL 0.64 - 0.67, HW 0.59, SL 0.64 - 0.66, PW 0.41, WL 0.80 - 0.82 (2 measured). Indices: CI 88 - 92, SI 108 - 112, OI 25 27, EPI 75 78, DTI 132.

Frontal carina with 2 setae: in profile one above the torulus and one at about the level of the anterior portion of the eye. Posterior to this is I pair of much shorter setae at level of posterior margin of eve, 1 pair between the latter and the posterior margin of the head that are shorter than'the maximum diameter of the eye, and 2 pairs at the posterior margin itself, a median pair and a much more lateral pair, all shorter than the maximum diameter of the eye. Scapes and tibiae without setae. Anterior clypeal margin transverse or at most with an extremely feeble median impression. In full-face view the posterior margin of the head appears transverse or even very slightly convex, but when head is tilted slightly forward from full-face the margin appears very shallowly evenly concave across its entire width. Outer margins of eyes just fail to break the outlines of the sides in full-face view. Number of setal pairs on mesosoma: pronotum 1; mesonotum 2; propodeal dorsum 0; lateral margin of propodeal declivity 2. Mesonotum in profile evenly rounded, without a differentiated declivitous face. Propodeal dorsum in profile very short, much shorter than depth of declivity to the spiracle; dorsum and declivity meet in an angle. Gastral tergites 1 - 4 with dense greyish pubescence and each with several pairs of setae, the longest on the first tergite about equal to the maximum diameter of the eye or fractionally shorter. Head and gaster brown to dark brown; mesosoma a much lighter yellowish brown and distinctly contrasting. All leg segments a dull dirty yellow, slightly lighter than the mesosoma.

Type Material
Holotype and paratype workers, Saudi Arabia: Wadi Shugub, 7.iv.l983 (CA. Collingwood) (location of types not known, not in ).

The type-series cannot be located. NHMB, the depository designated in the original descnption, has no record of them. However, in World Museum Liverpool are two workers with the data Saudi Arabia: Shaqiq, 8.iv.1983, presumably collected by Collingwood and incorrectly labeled as types In the Collingwood collection. The locality Shaqiq is not noted for this species either in Collingwood (1985) or Collingwood & Agosti (1996). Interpretation of selosus in this study is therefore based on these two specimens, which match the original description but not the rather sketchy figure.
