- Platypus flavicornis F. (figs. 29, male; 30, female): Males
have two stout spines on the end of the elytra. Females lack the spines,
but like the males, have a very elongate metathorax. Thus, the hind
legs appear to rise from the abdomen. The abdomen is very short relative
to overall body length. The tip of the elytra are squared off in the
middle. Average length for each sex is 5.0 mm.
