Ectatomma vizottoi Almeida Filho, 1987a: 180 (q.) BRAZIL (Mato Grosso do Sul). Neotropic.

Primary type information: Primary type material: syntype queens. Primary type locality: Brazil: Mato Grosso do Sul, Três Lagoas. Primary type depository: MZSP. Primary type specimens: MZSP0083443, MZSP0083444. Type notes: 1) No indication of number of specimens is given in the original description. 2) Mônica Antunes Ulysséa cites two syntype queens in MZSP and gives the locality data Três Lagoas, MS, Brasil. 3) The type depository was not stated in the original description but the introduction mentions four depositories: DBUP, DZUP, JLDC, MZSP. 4) Mônica Antunes Ulysséa cites one worker in MZSP labeled as "holotype" (MZSP0083442), but as this species was described by the queen, this is probably a "nidotype".
