Distribution. Guyana: see under D. feeri . Suriname: see under D. feeri . French Guiana: see under D. feeri . Brazil: Paulian 1938: 271 (as D. (Deltochilum) valgum ); Vulcano and Pereira 1964: 659 (as D. (Deltohyboma) valgum ); Vaz-de-Mello 2000: 192 (as D. (Deltohyboma) valgum valgum ).

(Deltochilum) valgum ); Blackwelder 1944: 203 (Argentina); Martínez 1959: 55 ([Argentina], Bolivia, Paraguay - as D. (Deltohyboma) valgum ); Vulcano and Pereira 1964: 659 (Argentina, Colombia - as D.

Note. Based on the distributional data in Silva et al. (2015), all previous records of Deltochilum valgum from the Guianas concern the newly described D. feeri and are placed there. The true D. valgum is restricted to Argentina, Bolivia and Paraguay. The records of D. valgum from Brazil and Colombia seemingly belong to some of the other species newly described by Silva et al. (2015).
