Group rufipes

Description follows Prous et al, 2017. Additional research is needed to delimit the species more reliably in this group and the species are not keyed beyond group level in Prous et al (2017). 

Despite the problems in delimiting species there are some characteristics common to the group. The species in the group are for the most part black bodied. The sawsheath has distinct invaginations and the lancets lack setae. The penis valves are similar to Pristiphora cincta but are more elongate. The pseudoceps is unmodified and more or less rectangular, the paravalva is dorsoapically abruptly narrowed before the valvispina. The valvispina is small, straight and arises on the ventral part of the paravalva. There is a distict valvar strut along its entire length.

The larvae feed on Aquilegia spp. (columbines) and Thalictrum spp. (meadow rues).
