is considerably larger, and differs by this male character. P. punctipennis has a similar 
male character, but the tarsi are rather shorter and their clothing somewhat longer ; 
it also differs in the sculpture and clothing of the upper surface of the body. From 
P. centralis the species may be distinguished by the rather larger size, by the differently 
formed male tarsi, and also by the tarsi in the female being considerably larger than 
they are in the corresponding sex of P. centralis.
