Appendages relatively short, in particular the tibiotarsi of the two foremost pairs of legs (Fig. 115A). Viewed from above the sides of the head with a small angular projection outside the bases of antennae caused by the forwardly directed two anterior ocelli (Fig. 3). Abd. 5–6 almost fused, with a weak break in setal cover. Colour shiny black or violet black apart from the two distal pure white antennal segments. Second antennal segment often paler in distal part. Occipital area of head with two small white spots. Distal part of tibiotarsi pale. Ocelli 6+6, the two anterior (A and B) enlarged and placed close to antennal bases, directed forward (Figs. 2–3); ocelli G & H invisible. PAO narrow, almost hidden between antennal base and the two anterior ocelli; only one seta below PAO. Ant. 1 on ventral side with two small apical sensilla and up to 13 elongate sensilla (Fig. 4). ...
