Description

About 8 to 10 mm. A handsome ground beetle, which has a blue colouration to its elytra, but this can vary in different light conditions.

Similar Species

Very similar to L. fulvibarbis  and best separated by the pronotum characters. In L. spinibarbis the flattened and punctured side margins are much wider than in L. fulvibarbis and in L. fulvibarbis the pronotum is more srtrongly contracted towards the base and there is a distinct straight portion immediately in front of the base, while in L. spinibarbis the curve continues almost to the base. (see diagram)

There is also fine wrinkling on the head of L. spinibarbis whereas L, fulvibarbis lacks this.
