Agonum scitulum Dejean, 1828

Description: 5.5-7mm long black ground beetle of well vegetated marshland and riverbanks. Widespread throughout GB but very local.

NI account: Janson (1924) published a record of Agonum scitulum for Shane's Castle Estate, Lough Neagh where it was found with A. micans. The record has not been verified, and references to Agonum scitulum from the same area in Speight et al. (1983) and Anderson (1986) relate to a variety of A. micans. This has a strong greenish dorsal reflection and is also darker than normal micans, lacking the distinctly paler first antennal segment and pale tibiae. It might key to scitulum using Lindroth (1974) but the shape of the pronotum, the brown colour of the elytral epipleura and form of the aedeagus are distinctive. Agonum scitulum was omitted from a recent checklist of Irish Coleoptera (Anderson et al., 1997).

Distribution: A rare species of west and central Europe with records from the southern half of Britain; Suboceanic temperate (72).
