Note. The report of Gromphas aeruginosa from the Guianas in Vulcano and Pereira (1967: 566) is probably incorrect according to Cupello and Vaz-de-Mello (2013: 448). We suspect that at least part of the records from Venezuela concerns G. lemoinei, which has been considered a variety of G. aeruginosa in for example Gillet (1911b: 80) and Blackwelder (1944: 208). Based on records from locations north of the Amazon in the Brazilian states of Amazonas and Pará as mentioned in Cupello and Vaz-de-Mello (2013), we still regard G. aeruginosa as potentially occurring in the Guianas.
