Brazil : Harold 1869c: 135 (as Pinotus luctuosus ); Blackwelder 1944: 207 (as Pinotus luctuosus ); Vaz-de-Mello 2000: 193 . Note. The only records of Dichotomius luctuosus for the Guianas are in Gillet (1911b: 61) and Blackwelder (1944: 207) , but it is unclear on which information these records were based. Because there are no recent records of this species for the research area, we consider its occurrence there doubtful and in need of confirmation.
