Primary type information:
Primary type material: syntype minor workers (number not stated). Primary type locality: Madagascar: Centre (no further data) (Hildebrandt). Primary type depository: MNHU (perhaps also MHNG).
The lectotype designation by Rakotonirina & Fisher, 2018: 35, consisting of lectotype minor worker, 1 paralectotype major worker, 1 paralectotype queen, Madagascar: Imerina, Antananarivo (Camboué), is redundant as this locality and collector do not appear in the original description; the Camboué specimens apparently derive from Forel, 1891c: 61, and Forel, 1891c: 216, not from the 1886 type series.
