Apis florisomnis minima CHRIST 1791; Apis florisomnis THOMSON 1872
Description and notes
A predominantly black bee; the abdomen is narrow and cylindrical, which is probably an adaptation to using small-bore beetle burrows as nest sites. The males have the final segment of the abdomen modified to form a two-pronged peg which is used to hold on inside flowers during the night or in poor weather, which gives a good method for recording the bees under such conditions.
