Note 1. Opinions vary as to whether Megasoma janus  , M. janus argentinum  , M. janus fujitai  and M. ramirezorum  are valid taxa or synonyms of M. actaeon  . Because differences are subtle, we merely mention these taxa here and take no position regarding the validity of these names. See Morón (2005: 30) for a rough overview of distributions.

Note 2. Five papers ( Prandi 2016, 2018a, 2018b, 2019; Van Meenen and Schouteet 2018) on Megasoma actaeon  have recently been published, all of them dealing with its purported subspecies, with some new, closely related, taxa being described. It appears these papers are partially overlapping, with at least one taxon (found outside the research area) being newly described twice. We consider the presented characteristics between all these species, subspecies and forms rather minimal given their variation within the newly defined taxonomic bounderies, especially as no genetic evidence is produced. Although the distribution of a taxon described in Prandi 2016 is within the research area, we have refrained from including it in this checklist until more solid evidence for its validity is provided.
