Apion is a genus of beetles from the group of black weevils ( Apioninae ).
features
The species of the genus are immediately recognizable within the subfamily by their completely red to red-orange body. Their body is elongated oval, usually widened backwards. The upper side is very thin and inconspicuously hairy in most species, only in a few (e.g. rubens , graecum ) thin but clearly hairy. They reach lengths between approx. 2.2 mm and 4.5 mm (without trunk).
history
The genus Apion was established in 1797 by Johann Friedrich Wilhelm Herbst . Before that, species such as B. Apion frumentarium of Linnaeus counted to the genus Curculio . At that time Apion comprised all species of the current subfamily Apioninae. The numerous sub-genres have meanwhile been raised to the rank of independent genres. For details see Apioninae # systematics .
In the genus Apion, according to today's view, a good dozen completely red species remain. However, numerous inadequately investigated species whose genus affiliation is unknown, especially from the tropics, are still listed as incertae sedis in the genus Apion . (E.g. in)
Distribution and Biology
All species of the genus live both as adults and as larvae on various plants of the genus Rumex ( dock ) or the closely related genera Emex and Rheum . Some species are monophagous , others are found in different species of dock .
The focus of distribution of the genus is Europe, western Asia and North Africa. Some species occur as far as East Asia, one ( Apion carrorum ) has been described from North America.
