In this male the clypeus (dotted pink arrow) is protruding and largely white, although black laterally and apically; the labrum (solid green arrow) largely black, but white-cream laterally. The mandible is pale in colour, the base just visible tucked in behind the labrum.
Note also the large, arched process on S2 (star).
