Shattuck (2006) - General features as illustrated. Dimensions as follows: aggregate total length c. 4.1 mm; maximum head length 0.91 mm; maximum head width (behind eyes) 0.74 mm; maximum diameter of eye 0.19 mm; scape length 0.64 mm; cephalic index 81; scape index 87; width across pronotal humeri 0.59 mm; Weber's length of thorax 1.03 mm; dorsal petiole width 0.21 mm; maximum petiole height 0.58 mm; dorsal postpetiole width 0.30 mm; maximum postpetiole height 0.60 mm.

Clypeal disc, frons between frontal carinae, thorax, petiole, postpetiole and gaster generally shining, though virtually nowhere entirely smooth, but with a minute and very finely incised net or scale-like microreticulation. Superimposed macrosculpturation on various parts as follows: lateral areas of clypeus longitudinally striate, some striae curving below and behind antennal foveae. Sides of head, especially anterior to eyes, finely longitudinally striate-rugose. Lateral areas of thoracic dorsum finely and irregularly longitudinally striate. Propodeal declivity smooth and shining, transversely convex below propodeal spines. Sides of thorax with fragmentary and scattered longitudinal striae. Petiole and postpetiole lacking macrosculpture, gaster relatively shining, microreticulate, with scattered minute blister-like hair follicles. Mandibles, antennae and legs moderately shining, with very fine, dense, piligerous point punctures and almost no microreticulation.

Head, thoracic dorsum and apices of nodes generally covered with short erect to suberect hairs. Longer suberect hairs abundant on mandibles, sides of clypeus, sides of head anterior to eyes, and gaster; those of mandibles and gastral apex longest, a few on crests of petiole and postpetiole.

Colour dull chestnut-brown, the gaster darker, eyes black.
