New records are provided for the following species: Aderus populneus (Creutzer, 1796) from Armenia, Azerbaijan and Cyprus; Otolelus flaveolus (Mulsant & Rey, 1866a) from Tessin and Valais (Switzerland), O. neglectus (Jacquelin du Duval, 1863) from Switzerland; O. ruficollis (Rossi, 1794) from Jordan, and Pseudanidorus pentatomus (Thomson, 1864) from Italy. Euglenes oculatus (Paykull, 1798) is excluded from the Italian fauna. The southernmost records for Pseudanidorus pentatomus (Italy, Latium) and Phytobaenus amabilis amabilis R. F. Sahlberg, 1834 (Italy, Calabria) are provided. The following synonymies are established: Xylophilus pruinosus var. testaceus Baudi di Selve, 1877b (not X. testaceus Kolenati, 1846) = Otolelus pruinosus pruinosus (Kiesenwetter, 1861) n. syn.; Xylophilus testaceus var. humeralis Favre, 1890 (not X. humeralis Champion, 1890a) = Otolelus neglectus (Jacquelin du Duval, 1863) n. syn. Escalerosia n. gen. (type species Hylophilus aculithorax Escalera, 1922) is described by validation of Escalerosia Báguena Corella, 1948 [nomen nudum]. Type species are designated for the following genus-group names: Pseudolotelus Pic, 1901 (type species Euglenes punctatissimus Reitter, 1885), Syzeton Blackburn, 1891 (type species Syzeton laetus Blackburn, 1891), and Syzetoninus Blackburn, 1891 (type species Syzetoninus mundus Blackburn, 1891). The following names are established to be unavailable: Carinatophilus Báguena Corella, 1948; Escalerosia yebonensis ab. benzanensis Báguena Corella, 1948; E. severini ab. telluricus Báguena Corella, 1948; E. bicolor var. binigropedes Báguena Corella, 1962; Hylophilus curtipennis var. tauricus Pic, 1917, and H. monstrosipes var. semibrunnescens Pic, 1917. Otolelus Mroczkowski, 1987, established as replacement name for Olotelus Mulsant & Rey, 1866a (not Olotelus Solier, 1851), lacks a type species and is an unavailable name; its authorship is attributed to Klinger (2000), who fixed Xylophilus pruinosus Kiesenwetter, 1861 as type species. Euglenes pygmaeus (DeGeer, 1775) is an incorrect subsequent spelling of pygmeus but is in prevailing usage, thus it is deemed to be a correct original spelling. Notoxus ruficollis Rossi, 1794, currently Otolelus ruficollis (Aderidae), and Notoxus ruficollis Champion, 1890 (Anthicidae) are homonyms but the senior homonym was placed in a separate genus before the junior name was described, so no immediate nomenclatorial action is required. Xylophile Latreille, 1825 is confirmed to be a vernacular unavailable name, whereas Xylophilus Latreille, 1829 (type species Notoxus populneus Creutzer, 1796) is a synonym of Aderus Stephens, 1829 n. syn. Xylophilus Curtis, 1830 (type species Anthicus oculatus Paykull, 1798), is removed from synonymy with Aderus Stephens, 1829 and is established to be an objective synonym of Euglenes Westwood, 1830 n. syn. Xylophilus bimaculatus is confirmed to be only a subsequent incorrect spelling (unavailable name) of X. bisbimaculatus Hampe, 1850. Euglenus, Aglenes, Helophilus, Pseudoloterus, Tokyophilus, Tokiophylus, Xilophilus and Xylophylus are established to be subsequent incorrect spellings (unavailable names) of Euglenes Westwood, 1830, Hylophilus Berthold, 1827, Pseudolotelus Pic, 1901, Tokiophilus Pic, 1921 and Xylophilus Latreille, 1829, respectively. Xylophila Lamarck, 1817 is excluded from the Aderidae; a formal assignment of this genus to a family based on a type species selection has not been done.
