The Palaearctic genus Trichomeloe is reviewed and newly defined on the basis of larval and adult characters. Its position among the Lyttini tribe is discussed. Trichomeloe includes eight species, mostly from the Near East. The bionomics of the genus is summarized, together with a key to the species, an annotated catalogue and some taxonomic remarks. T. syriacus n. sp. from Syria and T. mesopotamicus n. sp. from northern Irak, are described. The first instar larva of T. syriacus is described and compared with that of T. chrysocomus, both fi gured by scanning electron microscopy photographs.
