This one is a nest parasite of big Leaf Cutters like Megachile latimanus. Here are shots of a male and a female. You can see the long pointed abdomen that the female uses to cut into the nest walls and the odd multipronged rear ends of the males, the uses of which are not apparent to me...but all the Coelioxys males have them.
