Pristiphora lativentris - Moorland Sawyer
Pristiphora carinata group

Small numbers of records in the Scottish mountains; Benson (1958) described it as 'frequent in the arctic-alpine zones on the tops of the Grampian Mountains'. The single English record came from the Silverdale area of Lancashire which is known as a southern outpost of several other more northerly-distributed species (Musgrove, 2024).

The posterior of the mesonotum and the scutellum glossy between the punctures. A generally dark species with the hind femur infuscate. The female is best determined by the characteristics of the saw. Males are best determined by the penis valve.

Pristiphora lativentris larval food plant is unknown but the insect is associated with high moors in the arctic-alpine zone.
