Remarks. The Iranian population of P. scribneri (present study) closely corresponds to the original description. Thorne & Malek 1968 described P. agilis as being very close to P. scribneri. Hern��ndez et al. (2000) compared both species by non���morphological techniques, and found strong evidence that they are one species. They proposed P. agilis as a junior synonym of P. scribneri. Subramaniyan & Sivakumar 1991 also described P. crossandrae as a new species based on minor differences in b and c values and body annulation, therefore P. crossandrae was also considered as a new junior synonym of P. scribneri (Castillo & Vovlas 2007).
