Note 1. The year of publication of Tomarus fossor is sometimes erroneously given as 1833. Note 2. The only record of Tomarus fossor from the Guianas that we are aware of is one from French Guiana given in Blackwelder (1944: 254). Based on the lack of recent records, we suspect Blackwelder’s record is based on a mislabeled or misidentified specimen. A record from the state of Bolívar in Venezuela was given in Endrödi (1969a: 54) and repeated in Escalona and Joly (2006: 118). We regard this species as potentially occurring in the Guianas.
