Note. Karawajew (1927) gave the collection numbers for this species as 2496, 2479, 2490 and 2497, but the collection contains workers and males numbered 2459, 2476 and 2973, collected in the type locality (Amboina) and bearing Karawajew’s original labels “ Syntypus Polyrhachis coronata Sant. n. nov.”. He probably added these labels later, when Santschi (1928) proposed a replacement name for this species (see above). Since the mentioned materials undoubtedly are conspecific with other type specimens, we believe that they also belong to the type series of this species, and based on Recommendation 72B of the International Code of Zoological Nomenclature (ICZN 1999), we conclude these specimens are part of the type series.
