Remarks: Christiansen & Bellinger (1980, p. 1033) considered P. flavescens as a “polymorphic complex [which] does not segregate [in North America] into normal morphological species units”. Moreover, a modern combined morphological-molecular analysis demonstrated that P. flavescens , considered previously to occur over most of temperate North America, “probably does not exist naturally in the New World” ( Park et al. 2011, p. 1).

General distribution: Palaearctic and Nearctic (?).
