Distribution. Guyana: López-García et al. 2016: 500 (as O. cayennensis ). French Guiana: Burmeister 1847: 83 (as Chalepus nasutus ); Endrödi 1969a: 29 (as O. (Oxyligyrus) nasutus ), 1972: 23 (as O. (Oxyligyrus) cayennensis ), 1985a: 240 (as O. (Oxyligyrus) cayennensis ; as O. (Oxyligyrus) nasutus ); Duranton 2011: 19 (as O. cayennensis ; as O. nasutus ); Ponchel 2011: 61 (as O. cayennensis ); Brûlé and Dalens 2012a annex 4: 18 (as O. cayennensis ); López-García et al. 2015: 466 (as O. cayennensis ), 2016: 500 (as O. cayennensis ; as O. nasutus ); Dupuis 2016b: 110 (as O. cayennensis ), 2017b: 86. “Guianas”: Arrow 1937b: 39; Blackwelder 1944: 255. Brazil: Endrödi 1966b: 532 (designation NEOTYPE Chalepus nasutus [> Oxyligyrus endroedii Dupuis, 2017 ]), 1969a: 29 (as O. (Oxyligyrus) nasutus ), 1985a: 240 (as O. (Oxyligyrus) nasutus ); López-García et al. (2016: 500). Other: Endrödi 1969a: 29 ( Paraguay - as O. (Oxyligyrus) nasutus ), 1985a: 240 ( Paraguay - as O. (Oxyligyrus) nasutus ); Ponchel 2011: 61 (not mentioned - as O. nasutus ); López-García et al. 2015: 466 ( Colombia - as O. cayennensis ), 2016: 500 ( Colombia - as O. cayennensis ; Paraguay - as O. nasutus ); Dupuis 2016b: 110 (not mentioned - as O. nasutus ).

Note 1. According to Dupuis (2017b: 88), the designation of a neotype of Chalepus nasutus by Endrödi (1966: 532) is invalid as the holotype has been recovered in the MNHN. Endrödi’s neotype of C. nasutus belongs in fact to a new species from southern Brazil, Oxyligyrus endroedii Dupuis, 2017 ( 2017b: 89) .

Given the previous, it seems likely that all specimens of O. nasutus from Brazil and Paraguay mentioned by Endrödi (1966b, 1969a: 29, 1985a: 240) and López-García et al. (2016: 500) (who cite Endrödi (1985a)) belong to the newly described O. endroedii .

The specimens of O. cayennensis from Colombia mentioned by López-García et al. (2015: 466, 2016: 500) appear to belong, based on the drawings of their genitalia, to the true O. nasutus .

Note 2. The record of Oxyligyrus nasutus (mentioned as O. cayennensis ) from Guyana in López-García et al. (2016: 500) appears to be erroneous, as they mention their sole data source is existing literature while Guyana is not mentioned in the literature they cite for this species. As far as the research area is concerned, this species is only known from French Guiana.
