The following notes on F. Smith type specimens have been provided by Barry Bolton (details):

Polyrhachis chalybeus

Holotype worker in Oxford University Museum of Natural History. Labelled “MAL-CA,” and with a Donisthorpe type-label. Smith gives the type-locality as “Singapore, Malacca.” Specimens are also present in Oxford University Museum of Natural History from Sarawak (SAR.) and Sumatra (SUM.). One Sumatra specimen has the gaster very finely and densely reticulate-punctate. Normal variation or a separate species?
