Astenus pulchellus

3.5 - 4.5mm. Generally black (but can be paler brown) and usually with yellow extending variably upwards from the end of the elytra either side of the suture. The head and pronotum are heavily punctured such that the spaces between them appear as reticulate ridges. Legs and antennae are yellow. The pronotum has two long hairs projecting from either side, though this can be variable. Examining the male aedegus is generally the only safe way to confirm the species. Images in a pink box are thought to be this species but can't be confirmed.
