Canthidium (Neocanthidium) smaragdinum Harold, 1867

Canthidium smaragdinum Harold, 1867a: 16 [here transferred to the subgenus Neocanthidium]. Type locality: Brazil and French Guiana (“ Brasilien, Cayenne”). Type material: Location of syntypes unknown. Distribution: Brazil and French Guiana (Harold 1867a) [Although explicitly saying two years earlier that his specimens came from both Brazil and Cayenne, Harold (1869a) modified the distribution of C. smaragdinum and restricted it to Brazil, which was followed by Blackwelder (1944) and Martínez & Halffter (1986a). Gillet (1911), on the other hand, considered C. smaragdinum a junior synonym of C. viride Lucas, 1859, as done earlier by Harold (1869b). Since an argument for the exclusion of French Guiana from the distributional range of C. smaragdinum was never presented in the literature, I have decided to follow Harold’s (1867a) original report].
