On some species of the genus Anthonomus Germar (Coleoptera, Curculionidae) of phytosanitary importance for the Russian Federation

The article is devoted to four harmful weevil species of the genus Anthonomus Germar, being of phytosanitary importance for the Russian Federation, namely: Anthonomus signatus Say, 1831, Anthonomus eugenii Cano, 1894, Anthonomus grandis Boheman, 1843 and Anthonomus quadrigibbus (Say, 1831). It provides data on the composition, distribution and trophic preferences of the genus Anthonomus, one of the most numerous in species among Curculionidae, as well as the invasion potential of its representatives. It outlines the general information about each of the four stated harmful species, including the data on its distribution, host plants, biology, quarantine status for certain countries and international organizations, its invasion beyond its natural area. There has been studied and thoroughly discussed the morphology of some of its body parts bearing diagnostic characters easy to use. It concerns, primarily, the shape of the fore femurs and fore tibiae, the structure of male aedeagus and the color of the hairs that make up the pubescence of beetles. Based on these and some other characters, a diagnostic key to the mentioned four species of the genus Anthonomus has been proposed. The direction of further research on the stated topic is indicated. All images of beetles and individual parts of their bodies used in the article are original; the “Materials and Methods” section provides methods for obtaining and subsequent processing of these images. The article is of interest to entomologists, specialists in the field of phytosanitary biology and plant protection.
