List of species of the family Helophoridae of Russia

Helophorus ís the only genus in the beetle family Helophoridae (traditionally included within Hydrophilidae as the subfamily Helophorinae). They are small insects, found mainly in the Holarctic region (150 occur in Palearctic and 41 species in North America), but two or three species also live in the Afrotropical region, Central America and one in the Indomalayan region (northern India).[1][2]
Characteristics

Length about 2–9 mm. Body elongate with outline more or less interrupted between pronotum and elytra. On pronotum they have granulate sculpture and unique pattern of 7 longitudinal grooves. Ventral surface is with fine microsculpture, pubescent. Larvae are with long 3 segmented urogomphi and simple (non lobate) 8th tergum. They have four-segmented legs and a 10 segmented abdomen (with the 10th segment being a bit reduced).[3] Helophorus larvae may damage wheat, turnips, rutabagas, and rapeseed.
Systematics and evolution

Helophoridae belong to the superfamily Hydrophiloidea, and may be the sister taxon of Hydrochidae,[4] or a clade comprising Hydrochidae, Hydrophilidae and Spercheidae or Georissidae and Epimetopidae.[5] Earlier systems included all of these families in the family Hydrophilidae. There are about 180 living species, including:
