Primary type information: Type-material: 3 syntype workers. Type-locality: Brazil: Rio de Janeiro, Constancia, i.1857, 57/43 (H. Clark). Type-depositories: BMNH, OXUM. Type notes: Two further workers are present in BMNH that are identical and probably originated in the type-series, but they have passed through the Farren White collection and have lost their original labels. One other possible syntype is in MZSP (Lattke, 2011: 152).
