Formica atriceps Smith, 1858a: 44 (s.w.) BRAZIL (Pará). Neotropic.

Primary type information: Primary type material: syntype major and minor workers (numbers not stated). Primary type localities: Brazil: Pará, Belém (no collector’s name; perhaps H.W. Bates) (invalid restriction of type-locality by Kempf, 1972b: 59; no lectotype designated), Brazil: Pará, Santarem (no collector’s name; perhaps H.W. Bates), Brazil: Rio de Janeiro (no collector’s name). Primary type depository: BMNH. Type notes: Hashmi, 1973b: 85, cites a BMNH specimen as holotype, but from Smith’s original description it is obvious that several specimens were involved.
