Remarks. The Iranian population of P. flakkensis   closely corresponds to the original description (Seinhorst 1968). It is characterized by having a labial region with two annuli, lateral fields with four lines, rounded spermatheca filled with sperm, and subcylindrical tail with annulated tip (there are 18–19 annuli on ventral side of the tail). Three species, P. loosi Loof 1960   , P. alleni Ferris 1961   and P. convallariae Seinhorst 1959   are close to P. flakkensis   . Comparison of type materials of P. flakkensis   with these three species was made. The Iranian population of P. flakkensis   differs from P. loosi   by having an annulated vs smooth tail tip and rounded vs rectangular spermatheca, from P. alleni   by annulated vs smooth tail tip, length of the stylet (16.8–17.5 vs 13.5–15 µm) and single row of oocytes vs double and from P. convallariae   by two vs three lip annuli, long vs short postvulval uterine sac and annulations of the tail tip (regular vs irregular).
