cryptoceroides

Sides of head behind eyes smooth and shining between widely scattered pits, not blanketed by reticulate-punctate sculpture and never with rugulae in this area.

Propodeal dorsum strongly rugose, without or only with vestiges of punctate sculpture.

Pronotal dorsum closely and coarsely rugose, without dense punctate ground-sculpture.

Propodeal spines in dorsal view with their basal portions projecting outwards before angling backwards (Fig. 11), the projecting portion concealing the spiracle which is not at all visible from above.

Propodeal spiracle large and relatively close to the margin of the declivity below the spine; diameter of spiracle equal to or greater than the distance separating the spiracular hind margin from the edge of the declivity at its closest point (Fig. 9).
