§ Jansonia anceps ( Janson, 1875)

Gymnetis anceps Janson 1875: 373 ( French Guiana)

Distribution. French Guiana: Janson 1875: 373 (as Gymnetis anceps ); Schenkling 1921: 91 (as Gymnetis anceps ); Blackwelder 1944: 263 (as Jansonella anceps ); Ratcliffe 2014: 370. Other: Ratcliffe 2014: 370 (Ecuador).

Note. The records of Jansonia anceps from French Guiana in Schenkling (1921: 91) and Blackwelder (1944: 263) are likely copied from the original description in Janson (1875: 373). The two specimens on which this description is based may have been mislabeled, as we are unaware of any recent records from the research area. Based on collection material, Ratcliffe (2014: 370) believes the species to be present in Ecuador rather than in French Guiana. We agree with this opinion and regard the species as not occurring in the research area.
