Hyboma orbignyi Blanchard 1846: 156 View in CoL Note. Two presently recognized subspecies of Deltochilum ( Hybomidium) orbignyi have been described, one of which occurs in the research area while the other one was thought to occur there due to misidentifications.

§ Subspecies Deltochilum ( Hybomidium) orbignyi orbignyi ( Blanchard, 1846)

Hyboma orbignyi Blanchard 1846: 156 ( Argentina) View in CoL

Distribution. Guyana: Paulian 1938: 262 (as D. ( Tetraodontides) orbignyi ). Suriname: Paulian 1938: 262 (as D. ( Tetraodontides) orbignyi ). “Guianas”: Vulcano and Pereira 1964: 650. Brazil: Vulcano and Pereira 1964: 650; Vaz-de-Mello 2000: 192. Venezuela: Paulian 1938: 262 (as D. ( Tetraodontides) orbignyi ); Vulcano and Pereira 1964: 650. Other: Blanchard 1846: 156 (Argentina - as Hyboma orbignyi ); Gillet 1911b: 36 (Argentina); Paulian 1938: 262 (Argentina?, Bolivia, Colombia - as D. ( Tetraodontides) orbignyi ); Blackwelder 1944: 203 (Argentina); Vulcano and Pereira 1964: 650 (Bolivia, Colombia); Medina et al. 2001: 136 (Colombia); Noriega et al. 2007: 82 (Colombia); González-Alvarado and Vaz-de-Mello 2014: 448 (Argentina, Bolivia).

Note. According to González-Alvarado and Vaz-de-Mello (2014: 448), Deltochilum orbignyi orbignyi is restricted to Argentina and Bolivia. They state that the record of D. orbignyi for Colombia in Medina et al. (2001: 136) actually concerns D. guildingii . We suspect that all other records for the Guianas, Venezuela and Colombia of this species are also referable to D. guildingii . We have no proof for this though, and for now regard these records as misidentifications.
