According to Herman (2001) 24 species of the genus Eleusis were known from the Neotropical region before this study. Among these, the following 11 species are newly synonymised: E. cephalotes Bernhauer, 1904, and E. puncticeps Bernhauer, 1921 are synonyms to E. bicolor (Erichson, 1840); E. dubius (Sharp, 1876), Eleusis infima Sharp, 1887, E. marginicollis Bernhauer, 1921, E. armuellensis Bierig, 1931 are synonyms to E. nigerrima Fauvel, 1864; E. pallidipennis (Fauvel, 1864), E. corvina Sharp, 1887, E. flavipennis Sharp, 1887, and E. darlingtoni Blackwelder, 1943 are synonyms to E. interrupta (Erichson, 1840); E. mixta Sharp, 1887 is synonym to E. sctia Sharp, 1887. The new genus Eleusima is described with the new species E. platysoma spec. nov. The following new species of the genus Eleusis are described: E. genieri spec. nov., E. castanea spec. nov., E. rufipennis spec. nov., E. ecuadoriensis spec. nov., E. andina spec. nov., E. boliviana spec. nov., E. hondurana spec. nov., E. nigrita spec. nov., E. elongate spec. nov., E. panamaensis spec. nov., E. peruviana spec. nov., E. struyvei spec. nov., and E. tenuis (Fauvel, 1864), formerly synonymised with E. humilis, was found to be a distinct species and named here E. fauveli spec. nov., E. indica Kraatz, 1859, also synonymised with E. humilis (Erichson, 1840) is a distinct species as well, but not part of the Neotropical fauna. Overall, 24 Eleusis species are now known from the Neotropical region which can be separated into 3 species groups.
