Taxonomic History (provided by Barry Bolton, 2022)

Eciton rapax Smith, 1855c PDF: 163, pl. 13, figs. 3, 4 (s.) BRAZIL (Pará). Neotropic. Primary type information: Type-material: holotype [recte: lectotype (by designation of Borgmeier, 1955 PDF: 211)] worker (major). Type-locality: Brazil: Pará, Belém (H.W. Bates) (by restriction of Borgmeier, 1955 PDF: 211). Type-depository: BMNH. Type notes: 1) Smith originally also included minor workers in his type-series, from Brazil: Santarem (Bates); these were excluded from the type-series by Borgmeier, 1955 PDF: 211, who identified them as Eciton burchellii. 2) In the figure legends of Smith, 1855c PDF: 169, pl. 13, the name rapax is misspelled as raptor; an incorrect subsequent spelling that does not enter into homonymy.

Hab. Brazil (Para; Santarem; Ega).

This species is readily distinguished by its having the head, thorax, legs and nodes of the abdomen opake black, and the abdomen pale reddish yellow. Mr. Bates says, "This is the largest species of the genus that I have seen; its columns are narrower than those of the other species, in fact they generally run along in single file, and forage in the same way. I have found them carrying off great numbers of cocoons of a species of FormicaHNS; I have searched the columns long and repeatedly without finding any individuals with large heads and long mandibles."
