Nest entrance complexes of the meliponine Pariotrigona klossi Schwarz were studied on a limestone rock face in S Thailand. Unique in several aspects, a complex consisted of several coral-like clumps, all interconnected by roofed conduits. Inside these conduits, which were firmly attached to the substrate, the bees crawled on bare rock. The clumps were composed of dozens of entrance tubelets of up to 10 cm long, 2.5-6 mm wide, ornamented with radially arranged, 1-7 mm long, often branched, strings of crystal-clear beads of resin. Connection to the nest was through a fissure in the rock via a hard resin tube connected to the roofed conduits. Generally only one worker bee occupied an entrance (opening gap 2-3 mm).

Pariotrigona klossi was innocuous even when a tubelet was destroyed, but breaking into the roofed conduits near the rock fissure caused a small group of workers to attack the intruder by pinching bites and unpleasant odor.
