Pristiphora malaisei - Malaise's Sawyer
formerly Pristicampus arcticus
Only two old records (Benson 1961b), although both from far north-west Scotland where subsequent recording efforts have been minimal (Musgrove, 2024).
An alpine species only found occasionally in Scotland on high ground. The species was originally described within the Mesoseura genus as the type specimen had aberrant venation, something which is not uncommon in arctic species. It is a slender, dark species.
Pristiphora malaisei larvae feed on Shrubby Cinquefoil.
