Other: Westwood 1835: 372 (none - as Hyboma guildingii); Buquet 1844: 19 (Colombia as Hyboma chalcea); Gillet 1911b: 35 (Colombia - as D. chalceum; not mentioned - as D. guildingii); Blackwelder 1944: 202 (Colombia - as D. chalceum; not mentioned - as D. guildingii); Medina et al. 2001: 136 (Colombia - as D. orbignyi); González-Alvarado and Vaz-de-Mello 2014: 451 (Colombia, Panama, Trinidad and Tobago - as Deltochilum (Hybomidium) guildingii; none - designation LECTOTYPE Hyboma chalcea).

Note 1. Paulian (1938: 262) considered Hyboma chalcea a synonym of Deltochilum orbignyi, while Vulcano and Pereira (1964: 649) considered H. guildingii a synonym of D. icarus . These synonymizations are discussed and invalidated in González-Alvarado and Vaz-de-Mello (2014: 449, 454).

Note 2. The records of Deltochilum gibbosum from Guyana and Venezuela east of the Orinoco in, respectively, Forsyth and Gill (1993: 70) and Ferrer-Paris et al. (2013: 109) are probably attributable to misidentifications. D. gibbosum is a species from North America, and the species D. densepunctatum, D. sublaeve and D. panamensis, which for some time were considered subspecies of D. gibbosum, appear to be confined to Mexico ( D. densepunctatum and D. sublaeve) and Costa Rica, Colombia, Ecuador, Panama and Peru ( D. panamensis). The material mentioned in Forsyth and Gill (1993) and Ferrer-Paris et al. (2013) probably belongs to D. guildingii, but as we cannot confirm this, we have not included these records here.

Note 3. According to González-Alvarado and Vaz-de-Mello (2014: 454), the record of Deltochilum orbignyi for Colombia in Medina et al. (2001: 136) concerns in fact D. guildingii . Several more authors (Paulian 1938: 262; Vulcano and Pereira 1964: 650; Noriega et al. 2007: 82) have mentioned D. orbignyi (now D. orbignyi orbignyi) for the Guianas and/or Colombia, but according to González-Alvarado and Vaz-de- Mello (2014: 448) this subspecies is restricted to Argentina and Bolivia. As we are unable to examine the relevant specimens to confirm our assumption that they too belong to D. guildingii, we have not included them here. See also under D. orbignyi .
