Tribe Rhizotrogini

With some 10,000 described species, and many more still undescribed species, the Melolonthinae are an example of an extremely species rich phytophagous beetle lineage. They constitute an ecologically and taxonomically diverse group within the Scarabaeoidea (Scarabs, Chafers, June Beetles etc…). The Melolonthinae are characterized, among others, by white grub larvae that feed on the roots of grasses, palms and various groups of trees. Many species occur in grasslands and are crop pests (Hurpin, 1962; Britton, 1978). The most severely affected plants occur in the tropical regions, but severe damage to agriculture also has been reported in many regions. In Western Europe, damage is mainly caused by species of the genera Melolontha Fabricius, 1775 (Régnier, 1950; Hurpin, 1962) and Amphimallon Berthold, 1827 (Régnier, 1939, 1940, 1950; Gambrell, 1946; Hurpin, 1962).

The Rhizotrogini is a large tribe of Melolonthinae, which groups together about 1400 species from Palaearctic, Nearctic, Neotropical and Oriental regions (Sabatinelli and Pontuale, 1998).

Genus Amphimallon

This genus is composed of approximately 60 species inhabiting the Western–Palaearctic region. It is distributed across Europe (except in the northern regions), in the Middle East, from Central Asia to Siberia, and in Northern Africa (Morocco, Northern Algeria). Despite recent phylogenetic and taxonomic work focusing on the Rhizotrogini (Medvedev, 1951; Baraud, 1977, 1985, 1992; Coca Abia, 1995; Montreuil, 2000 and 2008).
