The Ecuadorian territory is divided into four natural regions: the coastal lowlands, the Andean highlands, the Amazon basin and the Galapagos Islands. Each of these regions has its own ecosystems and specific vegetation. The purpose of this work is to compile an updated catalog of the Scarabaeinae (Coleoptera: Scarabaeidae) of Ecuador that includes distributional data and several nomenclatural acts. We compiled data from 26 scientific collections, with the examination of 13,550 scarabaeines; additionally, 375 bibliographic references were reviewed for their taxonomic histories. The Scarabaeinae fauna from Ecuador contains 33 genera and 219 species, with 45 range-restricted (endemic) species and eight records erroneously attributed. The following nomenclatural acts are made: new status as valid species (3): Canthon (Glaphyrocanthon) ohausi Balthasar, 1939 stat. n.; Deltochilum (Calhyboma) arrowi Paulian, 1939 stat. n; and Dichotomius (Dichotomius) angustus (Luederwaldt, 1923) stat. n. New synonyms (4): Deltochilum (Deltohyboma) aureopilosum Paulian, 1938 syn. n.; Dichotomius (Dichotomius) provisorius Luederwaldt, 1925 syn. n.; Dichotomius (Dichotomius) hempeli Pereira, 1942 syn. n.; and Uroxys magnus Balthasar, 1940 syn. n. Revalidated names (4): Canthidium (Canthidium) orbiculatum (Lucas, 1859); Coprophanaeus (Coprophanaeus) florenti Arnaud, 2002; Dichotomius (Luederwaldtinia) fortepunctatus (Luederwaldt, 1923) and Phanaeus (Notiophanaeus) pyrois funereus Balthasar, 1939. Revised status (1): Canthon (Glaphyrocanthon) subhyalinoides Balthasar, 1939. New combination (1): Uroxys ohausi (Balthasar, 1938) comb. n.
