Pristiphora subopaca- ruficornis group
This species cannot always be distinguished by morphology from Pristiphora confusa. Males are best determined by examination of the penis valves. Determination of the females, is best done by examination of the saw where the apical serrulae are arguably less protruding and longer than in confusa.
Pristiphora subopaca larvae feed on goat willow and tea-leaved willow.
