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.
