Lectotypes of the following species are designated: Cathormiocerus alticola Escalera, 1918, Cathormiocerus alveolatus Desbrochers, 1900, Cathormiocerus britannicus Blair, 1934, Cathormiocerus carpetanus Uhagon, 1885, Cathormiocerus chevrolati Seidlitz, 1868, Cathormiocerus diecki Seidlitz, 1868, Cathormiocerus discors Desbrochers, 1875, Cathormiocerus escalerai Hustache, 1944, Cathormiocerus estrellanus Escalera, 1918, Cathormiocerus globicollis Stierlin, 1896, Cathormiocerus hircus Desbrochers, 1896, Cathormiocerus inhumeralis Pic, 1905, Cathormiocerus latinasus Desbrochers, 1910, Cathormiocerus maritimus Rye, 1874, Cathormiocerus maritimus var. armoricus Escalera, 1918, Cathormiocerus mogadoricus Escalera, 1918, Cathormiocerus moroderi Escalera, 1918, Cathormiocerus nevadensis Escalera, 1918, Cathormiocerus nodiscapus Escalera, 1914, Cathormiocerus pici Desbrochers, 1896, Cathormiocerus reitteri Stierlin, 1885, Cathormiocerus simplex Desbrochers, 1910, Cathormiocerus socius Boheman, 1843, Cathormiocerus porculus Uhagon, 1885, Cathormiocerus quezeli Hoffmann, 1952, Cathormiocerus sinuosiscapus Escalera, 1914, Cathormiocerus tenuiscapus Fairmaire, 1884, Cathormiocerus tizintesti Escalera, 1914, Cathormiocerus validiscapus var. notatipennis Pic, 1912, Peritelus brevirostris Ch. Brisout, 1866, Scoliocerus curvipes Wollaston, 1854, Trachyphloeus myrmecophilus Seidlitz, 1868, Trachyphloeus picturatus Fuente, 1902 and Trachyphloeus socius Chevrolat, 1866. The following new combinations are proposed: Cathormiocerus aristatus (Gyllenhal, 1827), Cathormiocerus globicollis (Stierlin, 1896), Cathormiocerus jeani (Borovec, 1989) and Cathormiocerus spinosus (Goeze, 1777) - all from Trachyphloeus Germar, 1817. For Cathormiocerus escalerai Borovec & Bahr, 2007 a nomen novum Cathormiocerus hustachei Borovec & Bahr, 2008 is proposed. Due to the transfer of the former Trachyphloeus aristatus to Cathormiocerus aristatus (Gyllenhal, 1827) the eastern border of the distribution of the genus Cathormiocerus shifts from Italy to Kazakhstan and Siberia. The genus Chaetechus Horn, 1876 a former synonym of Trachyphloeus is a new synonym of Cathormiocerus Schoenherr, 1842 by the change of Trachyphloeus spinosus (= Chaetechus setiger Horn, 1876) to Cathormiocerus spinosus (Goeze, 1777). Relevant external characters and - if known - the male and female genitalia of all discussed taxa are illustrated. A new diagnostic key - in German and English - allows the identification of all species of the Cathormiocerus socius group.
