Abstract
Subfamily Cossoninae is distributed worldwide, with 287 genera based on latest literatures. Species of Cossoninae is found mainly in dead or dying plant parts of trees from pteridophytes to gymnosperms, and dicots, in case of feeding on alive or still sound tissues, the host specificity is high. In Egypt, it has seven genera including ten species. Those genera and species based on their latest position and changes according to latest literatures are Melicius gracilis (Rosenhauer), Melicius cylindrus (Boheman), Hexarthrum culinaris (Germar), Mesites pallidipennis Boheman, Mesites cunipes Boheman, Mesites cunipes var. cribratus Fairmaire, Choerorhinus squalidus Fairmaire, Amaurorhinus bonnairii Fairmaire, Pselactus spadix (Herbst), Micromesites deplanatus Pic. The species of these genera, which recoded in Egypt, is distributed in Mediterranean basin countries except the last species, which recoded only from Egypt. All those species collected from four regions, Maryut, Cairo, Ismailia and Alexandria, which located at North Egypt. They were found under the bark of old trees of willow, plane, mulberry, fig and Tamarix sp. during the whole year except the months of February, October and November. The fauna of Cossoninae probably are not reflecting the reality of which in Egypt, since those are not distributed throughout the country. So many weevil collections are required particularly from Middle and South Egypt in the next studies.
