Zoogeographically, this louse appears to represent an anomaly. It is the only species of Polyplax that is known to parasitize any native South American mammal. One of us (L.A.D.) has examined the holotype and confirmed that the original description is valid. Ferris (1953) examined additional material from A. cinerea collected at the type locality and reached a similar conclusion. [ex. Durden, L. A., Musser, G. G. 1994.

Taxon Citation Remarks:
Citation information points to the most recent interpretation of the taxon name (not the original, which is absent from the sucking louse checklist).
