Pachynematus clibrichellus ( CAMERON, 1878)

Dumfriesshire, White Coomb, north of summit, ca 750 m, 1 ♂, 19.vi.2010, leg. Liston.

Recorded by Benson (1958) from “Perths., Inverness, Angus, Sutherland and Caithness, mostly on mountain tundra, but at sea level at Wick in Caithness[..]”, but also found by Nelson (1971) at high altitudes in the northern Pennines of England. It is therefore of little surprise that Pachynematus clibrichellus has now been found on one of the highest hills in the Southern Uplands of Scotland, where a few other very local occurrences of ‘arctic-alpine’ sawfly species are already known ( Liston 1983b; 1984, record refers to Pontania herbaceae ).
