WORKER - Mesonotum with a single pair of erect hairs; head capsule somewhat shallower and a less convex profile; TL 2.0-2.2 mm, HL 0.53-0.57, HW 0.42-0.45, CI 79-81, MI 44-48, SL 0.32-0.34, SI 73-76.

comparison For no obvious reason, Bolton (2000) keyed out syntacta in two couplets, running from couplet 42, eyes 3-6 ommatidia or 10 ommatifia (7-8 if scape slender); into a separation from traegaordhi in couplet 47, and,separated from 53. The only reason offered but not actually stated is that of paratype workers "eye showing variation in size". Note he did not mention colour at all in his description or in couplet 47 for either species. In couplet 53 he had syntacta as a "Dark brown to blackish brown species".

The comparision right shows the heads of syntacta (paratype shown below), Santschi's (19i4e) drawing of traegaordhi and of traegaordhi from among those listed as seen by Bolton (2000).

Allowing for the possible slight inaccuracy of Santschi's drawing, the lefthand pair appear better matched than the righthand pair.   Santschi and Arnold (1917: 373) gave the colour of traegaordhi as dark reddish-yellow, sometimes brownish.  There seems merit, perhaps, in suggesting syntacta is no more than what earlier authors (e.g. Santschi) would have termed a variety.
