Table 1: Chronological account of the usage of names and nomenclatural acts applied to the collared peccary and the white-lipped peccary, at species (columns A-B) and genus (C-D-E) levels. The last column F gathers additional names or acts which are not currently considered valid, or a reference to the familial assignment. In bold: names when first proposed. Valid names or nomenclatural acts are indicated ***; junior synonyms as [syn]. Solid boxes: Tayassu is the only genus for collared and white-lipped peccaries; dashed boxes: the single genus is Dicotyles.
