From Young et al (2016):
1: female -> 79
79: no corners -> 105
105: tergites have pale spots -> 108
108: all femora yellow at base -> 110
110: yellow spots reach margins -> 112
112: T5 with pale spots -> 114
114: T2 spots reduced, lots of silver pollinosity, T6 dark -> 115
115: can't judge the wings but the extensive silver pollinosity ->
P. hyperboreus
Obviously Andrew Young should correct me if I'm mistaken!
