Copelatinae

Copelatus haemorrhoidalis, photographed by Gábor Keresztes.

Belongs within: Dytiscidae.

The Copelatinae is a speciose clade of diving beetles, most species of which are included in the genus Copelatus. Larvae, where known, are presumed solid feeders with serrated mandibles and a foregut including a crop.

Characters (from Miller 2001): Metacoxal lines closely approximated medially (metacoxal lines lost in Lacconectus); spermatheca strongly reduced; scutellum externally visible; metatarsal claws equal in length in both sexes.
