The Eleodes Eschscholtz, 1829 subgenera Tricheleodes Blaisdell, 1909 and Pseudeleodes Blaisdell, 1909 are reviewed and redefined, based largely on female ovipositors. Eleodes hirsuta LeConte, 1861 is designated as the type species of Tricheleodes, which is redefined to contain only that species. Eleodes barbatus Wickham, 1918 is placed as incertae sedis within Eleodes. Pseudeleodes is expanded to include Trichoderulus Blaisdell, 1923 syn. nov., as well as the following species: Eleodes caudiferus LeConte, 1858, E. leechi Tanner, 1961, E. longipilosus Horn, 1891, E. pilosus Horn, 1870, E. spoliatus Blaisdell, 1933, and E. tribulus Thomas, 2005, all comb. nov.; and Eleodes inornatus Johnston sp. nov. Eleodes granosus LeConte, 1866 is recognized as a single valid species, which includes Eleodes inyoensis Tanner, 1961 syn. nov. and Eleodes granosa pilifera Boddy, 1957 syn. nov. Eleodes caudiferus LeConte is similarly identified as a single valid species, which includes E. caudifera forma glabra Blaisdell, 1909 syn. nov., E. caudifera forma scabra Blasidell, 1909 syn. nov., and E. caudifera forma sublaevis Blaisdell, 1909 syn. nov. Eleodes pilosus Horn is found to be a single species including E. obesus Doyen, 1985 as a syn. nov. A key is presented for the species belonging to the subgenus Pseudeleodes. The new classification is reconciled with the cumulative preceding taxonomic perspective according to Blaisdell (1909) through Triplehorn and coauthors (2015), by representing both taxonomies and aligning their respective concepts with Region Connection Calculus (RCC-5) articulations. The resulting, logically consistent alignment is inferred and visualized using the Euler/X multi-taxonomy alignment toolkit.
