Note. To our knowledge there are no recent records of Scybalocanthon nigriceps for the research area. The records for French Guiana in Balthasar (1939e: 193), Blackwelder (1944: 200), Pereira and Martínez (1956b: 119) and Vulcano and Pereira (1964: 638) appear to have been taken from Harold (1868a: 49), with the latter possibly being based on a mislabeled specimen. According to Silva and Valois (2019: 329), this species is restricted to an area in southern Brazil, southern Paraguay and northern Argentina. This species is absent from the research area.
