Pristiphora luteipes - Yellowfoot Willow Sawyer
Pristiphora ruficornis group

North to northern Scotland. One of two species formerly lumped together under Pristiphora fulvipes. More records of the former fulvipes have been specifically associated with Salix, or else critically assigned to luteipes by Vikberg (2006) so as to allow for an assessment of the status of this taxon (Musgrove, 2024).

Males are unknown. This species cannot always be distinguished from Pristophora aphantoneura. The surface sculpture of the mesepisternum is not a reliable character. Separation of the two species is best achieved by detailed examination of the saw, though small differences in the hypopygium may also be diagnostic.

Pristiphora luteipes larvae feed on White Willow, Eared Willow, Creeping Willow, Tea-leaved Willow, Osier and Purple Willow.
