Comments. The types of P. discoideus and P.emelinae are similar in all external characters. After dissection and study of the male specimens from additional non-type material of P. discoideus , I was also able to confirm that P. emelinae and P. discoideus are identical in the shape of aedeagus. Therefore, these names are considered to be synonyms.
