Platynus sp., copyright Nick Block.

Belongs within: Platynini.

The Platynina are a group of ground beetles in which females have a fringe of setae along the apex of the penultimate segment of the gonostylus. The widespread genus Agonum, found in Eurasia, Africa and North America, is mostly found alongside standing or flowing water though some species are forest dwellers and the North American A. placidum is found in dry pastures (Ball & Bousquet 2001).
