Primary type information: Primary type material: lectotype worker (by designation of Kempf, 1951: 103). Primary type locality: Colombia: (no further data) (Landolt). Primary type depository: MHNG. Type notes: The original description implied the presence of more than one syntype. Longino & Snelling, 2002: 20, record two extant syntypes, neither of which had been labelled as the lectotype; they added the appropriate label to one of them.
