Corixa punctata, copyright Wolfram Sondermann.

Belongs within: Panheteroptera.

The Corixidae, water boatmen, are a group of aquatic bugs characterised by short forelegs with hair-fringed scoop-shaped or cylindrical tarsi. These are used to collect prey (mostly insect larvae) from bottom ooze. Hind legs are used for swimming and have long fringes of hair on the tibiae and tarsi. The dorsum of the abdomen is concave, allowing for the retention of a bubble of air beneath the wings.

The majority of living species are included in the subfamily Corixinae; members of the genus Micronecta are much smaller than species of Corixinae. The Diaprepocorinae differ from other corixids in the possession of ocelli and additional cuticular blades fringing the hind tarsi. Living diaprepocorines are restricted to southern Australia and New Zealand but fossil species are known from the Jurassic of Eurasia (Carver et al. 1991).
