The following species have been reported from Ecuador, but because they have been incorrectly identified, have never been collected since being reported, are so far out of their normal range, or the names have been misapplied, we consider the records to be erroneous, spurious, or otherwise suspect:
CYCLOCEPHALINI: Ancognatha quadripunctata Bates, Cyclocephalafreudei Endrodi, Cyclocephala rufescens Endrodi, and Stenocrates holomelanus (Germar).

PENTODONTINI: Tomarus fossor (Latreille).

ORYCTINI: Heterogomphus aidoneus (Perty).

PHILEURINI: Archophileurus burmeisteri (Arrow) and Archophileurus vervex (Burmeister).
