Corbels
Mon, 2009-07-06 06:54 — s_d_j_brownAccording to the Torre-Buenos glossary of entomological terms:
Corbel: an ovate area at the distal end of the tibia in Coleoptera, surrounded by a fringe of minute bristles; when the articular cavity is on the side, above the tip, the corbel is closed; when the cavity is at the extreme tip, the corbel is open.
I'm fine with where the corbel is located, but I'm having trouble picturing what it looks like when it's open or closed.
Anyone have a picture they could post, or know where one's published?
