Body length : 8-12mm.

This species is difficult to distinguish from L. turbinatus and L. planus.

L. turbinatus has a shorter rostrum than L. planus and L. sturnus. It’s also quite thick at the base but narrower towards the end.

L. sturnus is very broad overall build, whereas L. planus is slimmer.

A dorsal view and a good photo of the rostrum is needed to identify this species.
