Group abietina

Description follows Prous et al, 2017. This group all feed on spruce trees (Picea spp.). In Britain, the hostplants are widespread. Data on distribution in Britain and Ireland are scant but all the species in this group are likely to be found across the regions. The characteristics of the group are as follows. The valvula 3 is relatively narrow in dorsal view and in lateral view the apex is clearly truncated. In the females, the apical abdominal segments are laterally compressed, though this is not unique to this group. In common with many other Pristiphora species, the males in this group are largely black dorsally and pale ventrally. The penis valve have a more or less straight ventral margin and the paravalva and pseudoceps are of similar size with an approximately convex dorsal margin. The pseudoceps is unmodified apically and valvispina may be slightly bent or straight.
