Worker. TL 3.1-4.3, HL 0.86-1.04, HW 0.67-0.88, CI 78-88, SL 0.68-0.88, SI 98-104, PW 0.40-0.53, AL 0.95-1.24 (30 measured).
Anterior margin of median portion of clypeus evenly shallowly concave. Eyes large, the maximum diameter 0.30-0.35 x HW and with 12-14 ommatidia in the longest row. Sides of head evenly shallowly convex in full-face view, the occipital margin approximately transverse to broadly but shallowly concave. Pronotum and anterior portion of mesonotum in profile evenly convex; median portion of mesonotum flat to shallowly convex, sometimes even slightly indented; posterior one-third (approximately) of mesonotum suddenly sloping much more steeply to the conspicuously impressed metanotal groove. Highest point of propodeal dorsum behind the metanotal groove on a much lower level than the highest point of the promesonotum. In dorsal view the propodeum with a narrow flattened median longitudinal strip, the dorsum and sides separated by bluntly rounded margins.
Dorsum of head with 1-2 pairs of standing hairs, which straddle the midline; occipital corners without hairs. Dorsal alitrunk without standing hairs. Petiole node with one pair, postpetiole with 2-3 pairs (very rarely with 4 pairs) of backward directed hairs. First gastral tergite without standing hairs except for the apical transverse row, or at most with a single pair at or near the midlength of the sclerite.
Dorsum of head with fine dense reticulate to reticulate-shagreenate sculpture; this often extensively overlaid, especially mid-dorsally, by exceptionally fine dense scratch-like longitudinal sculpture. Dorsal alitrunk reticulate to shallowly reticulate-punctate, the propodeum more strongly sculptured than the pronotum; intensity of sculpture variable between series. First gastral tergite at least with superficial reticular patterning, more often this is overlaid by a secondary fine shagreening. Colour brown, very variable in shade.
I am grouping the names areniphilum, lepineyi and pullulum as a single species here, based on the following combination of five characters within the Salomonis-group.
- Eyes both relatively and absolutely large (see measurements above).
- Antennal scapes of moderate length (SI 98-104).
- Characteristic outline shape of dorsal alitrunk (Fig. 46).
- Cephalic sculpture (as described above).
- Very reduced dorsal pilosity (as described above).
