Formica esuriens Smith, 1858a: 54 (s.w.) MEXICO. Neotropic.

Primary type information: Primary type material: syntype major and minor workers (numbers not stated). Primary type locality: Mexico: (no further data). Primary type depository: BMNH. Type notes: 1) Hashmi, 1973b: 85, cites a BMNH specimen as holotype, but from Smith’s original description it is obvious that at least two specimens were involved (major and minor workers). 2) Smith never designated holotypes.
