Diagnosis

Remarks

The second author found M. griseola for the first time in the Sverdlovsk Region. Species of the genus Micronecta are the smallest representatives of the Corixidae family, the body length of the species ranges from 1.5 to 2.4 mm (Fig. 1 ). In M. griseola , as in other species of the genus, wing polymorphism is noted ( Wroblewski 1958). Large and slender full-winged, flying forms with almost parallel elytral margins are rare. Short-winged non-flying forms predominate. They are distinguished by a shortened pronotum and an elliptical body shape, with elytra narrowed towards the apex and shortened wings ( Kanyukova 2006).

Distribution

The range of distribution of the species is located in Western and Eastern Europe, from the British Isles ( Brooke and Nau 2003) in the west to the Western Siberia and Central Asia in the east, from southern Finland in the north to Italy in the south ( Kanyukova 2006). In the south of Russia, it is indicated from the North Caucasus ( Shapovalov et al. 2014).The species was found in the Middle (our material) and South Urals ( Wroblewski 1963). In the Ob Basin, the species was recorded from Novosibirsk ( Belevich and Yurchenko 2012) and the south of Tyumen Regions ( Kanyukova et al. 2019). It is known from the countries of Transcaucasia, Turkey, Kazakhstan ( Wroblewski 1963), Kyrgyzstan, Tajikistan ( Jansson 1986) and Northwest China ( Kanyukova et al. 2016).
