diagnosis
Diagnosis. An elongate second funicular article and broad triangular femoral tooth place Piazurus near Pseudopinarus and Pseudopiazurus, and it can be differentiated from them by the longer second abdominal ventrite (which is as long as the third and fourth ventrites when seen from the side) and the protibial apex that bears a premucro. Being a much more diverse genus than Pseudopinarus and Pseudopiazurus, it is easiest to arrive at an identification by a negative identification of those two smaller genera: namely, species of Piazurus never have a carinate vertex of the head (as in many Pseudopinarus), a strongly impressed first abdominal ventrite (as in Pseudopiazurus), or a subapical premucro (as in some Pseudopinarus and Pseudopiazurus) and usually do not have a mesal procoxal process (which is found in most Pseudopinarus and a South American Pseudopiazurus; it is present at least in Piazurus alternans).
