Identification
Rindge (1976) description in PDF. (1)
Most similar to P. personaria, but occurring more inland, often "montane", with "thorax above with longitudinal median crest; length of forewings 18 to 24 mm."
Distinguished from the often much paler P. californiaria by the inland localities, and then from this and diva by having a discal spot that is solid black with no central pale scales. Additionally the t.a. line tends towards acutely angled at junction of veins Cu1 and Cu2.
Range
Rindge (1976) reported California and western Nevada to Baja California. (2), (1)
