Remarks. Frederick & Tarjan (1989) pointed out that P. sefaensis Fortuner 1973   was not specifically compared with P. pseudopratensis   . In fact, P. sefaensis   can not be adequately separated from P. pseudopratensis   , and is therefore considered a junior synonym of P. sefaensis (Castillo & Volvas 2007)   . In Pourjam et al. 1997, this species was also considered as P. sefaensis   . The Iranian population of P. sefaensis (Pourjam et al. 1997)   closely corresponds to the original description (Fortuner 1973), but the lateral fields possesses four to six lines (vs four), and is sometimes structured as a wide band with a series of irregular lines similar to those of the Cameroonian population (Sakwe & Geraert 1994). Further, in some Iranian populations, the intestine overlaps the rectum.
