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