Exemplars: Male and female from Hwy 116, 3 mi W of Guerneville, Sonoma Co., California, 38.47858 - 122.99965 [MY0634, MY0635], 28 July 2002 (M. Hedin, P. Paquin, & J. Starrett), deposited in ECU–CAS.
Genbank Accessions: EF542846 –56, EF542858 –928, EF542930 –31, EF542934 –37, EF542939 –55, EF542959 –75, EF542977 –3047, EF543049 –50, EF543053 –56, EF543058 –74, EF543078 –83.
Diagnosis: Males differ from those of P. winnemem by having a dense clump of thickened setae and spines on distal–retrolateral aspect of tibia I (Figs 26, 31), and by ventral–to–retrolateral excavation on proximal third of metatarsus I bordered distally by moderately sized and readily apparent conical apophysis. Females differ from those of P. winnemem by having short, stout, nondescript spermathecae (Figs 29, 30, 33) lacking distinct side branch.
