Note. The only record of Gromphas amazonica for the Guianas that we are aware of is given in Olsoufieff (1924: 59), who mentions a specimen purportedly coming from French Guiana but casts doubt on the veracity of that origin. As Cupello and Vaz-de-Mello (2013: 462) record this species from the state of Amapá in Brazil, we regard it as potentially occurring in the Guianas.
