Remarks. The Iranian population of P. crassi closely corresponds to the original description (Das & Sultana 1979). It is characterised by having a flattened lip region with two annuli, lateral fields with four lines, the outer ones being crenate, spherical spermatheca filled with sperm, and cylindrical tail with rounded smooth terminus (there are 12–16 annuli on the ventral side of the tail). The Iranian population is morphologically similar to P. loosi and P. coffeae , in having two labial annuli and four lines in lateral fields. They differ from P. loosi in body length, having an anteriorly located vulva, tail terminus (rounded smooth vs conical) and absence of males. From P. coffeae , they differ in body length, anteriorly located vulva, tail shape (cylindrical vs truncate or hemispherical) and absence of males.
