Abstract
Nine species of genera Ennearthron Mellié, 1847, Orthocis Casey, 1898, Octotemnus Mellié, 1847, Sulcacis Dury, 1917, Rhopalodonthus Mellié, 1847, Xylographus Mellié, 1847 are recorded for Kazakhstan. Seven species (Ennearthron cornutum (Gyllenhal, 1827), Orthocis lucasi (Abeille de Perrin, 1874), Sulcacis nitidus (Fabricius, 1792), Octotemnus glabriculus (Gyllenhal, 1827), O. mandibularis (Gyllenhal, 1813), Rhopalodontus strandi Lohse, 1969 and Xylographus bostrichoides Dufour, 1843) are first reported from the country. The distribution in Kazakhstan of two species (Sulcacis bidentulus (Rosenhauer, 1847) and S. fronticornis (Panzer, 1809)) is clarified. A pseudoscorpion common tree-chernes Chernes cimicoides (Fabricius, 1793) is cited for the first time as a predator and an entomopathogenic fungus white muscardine disease Beauveria bassiana (Bals.-Criv.) as a parasite of minute tree-fungus beetles Sulcacis bidentulus, S. nitidus, S. fronticornis, Octotemnus. glabriusculus, Orthocis lucasi and Rhopalodontus strandi. (Hymenoptera, Bthylidae). A Bethylidae wasp Cephalonomia sp. is cited as a parasite of minute tree-fungus beetle E. cornutum. A key to known species of genus Ennearthron, Octotemnus, Orthocis, Rhopalodontus, Sulcacis and Xylographus from Kazakhstan is given. Currently, the countries neighbouring Kazakhstan have the following number of species of Ciidae in common with it: Russia – 16, China – 4, Kyrgyzstan – 3, Turkmenistan – 3, Uzbekistan – 2. In total, 16 species and 7 genera of minute tree-fungus beetles, belonging to two tribes and one subfamily, have been recorded for Kazakhstan at present.
