Formerly known as Dytiscus punctulatus F.

It is listed in the Catalogue of Life,[2]

Description edit

In this species the metacoxal plates are sharply pointed. It is 30 mm or more in length and the pronotum has narrow yellow borders front and back with the sides being only a little wider. Other distinguishing features are the underside of the beetle which is straw-yellowish with wide dark edges, the metacoxae & the last sternite are dark; the eyes have no pale rim and the scutellum has a yellow centre. The scutellum is usually dark in this species.[3] Habitat Freshwater ponds and lakes and canals. It flies well and may also be attracted to light.[3] UK Status Widespread in England and Wales, but seems to be rather local.[3]
