Distribution Most described species are found in the New World, especially from Mexico and the United States, but other species occur in South America. P. simoni is found only in Europe. P. nigromaculatus was described from New Guinea, but is certainly misplaced.Huber 2000
Name The first part of the genus name is from Ancient Greek psilos "naked". The second part could be derived from a Greek word for "dance", or "separate".
