Isonychus fasciolatus Blanchard 1850: 87 ( French Guiana)
Distribution. Guyana: Evans and Smith 2009: 239. French Guiana: Blanchard 1850: 87. Brazil: Dalla Torre 1913: 326; Blackwelder 1944: 230; Evans and Smith 2009: 239. Other: Frey 1970: 137 (none).
Note. Evans and Smith (2009: 239) mention Isonychus fasciolatus for Guyana, but not for the type locality French Guiana. We consider their “ Guyana ” as a misinterpretation of the location “ Guyane: La Mana” as mentioned in the original description by Blanchard (1850: 87). (The) Mana is both a river and a municipality in French Guiana, while there is no location with that name in Guyana. We are not aware of any records outside of French Guiana and Brazil.
