[Note: type material of Polyrhachis eudora is absent from BMNH and OXUM. A queen in OXUM and a worker in BMNH were formerly regarded as syntypes of this species. Both are labelled “Bac.” (=Bacan I.), the locality given by Smith, 1860b, and the queen has a Donisthorpe type label. However, it is apparent from Smith, 1860b’s description and figure that true Polyrhachis eudora belongs in subgenus Polyrhachis (Myrmothrinax), whereas both these specimens are of subgenus Polyrhachis (Myrma), and are not type material of Polyrhachis eudora (B. Bolton unpublished notes 1978).]
