[5] This species features a unique distribution of ozopores, which appear on all segments with two pairs of legs.
[7] They based the original description of this species on several specimens collected by Rundle from four hothouses in Kew Gardens in England.
[7] The geographic origin of this species, however, remained a mystery until 2012, when the zoologist Robert Mesibov reported the discovery of P. panporus specimens in a remote tropical rainforest in Australia.
These specimens include 24 males and five females collected in 1986 from rainforest litter on the Cape York peninsula of Queensland in Australia.
The gonopods are simple and end with several prominent teeth on the lateral edge, one apical and four or five near the tip.
[7] This millipede shares many features with other Prosopodesmus species, including the general form of the body, the fan-shaped collum covering the head from above, three rows of tubercles on the dorsal surface of the segments, and simple gonopods.
[7][8] This species may be distinguished from its close relatives, however, by its unique series of ozopores and the number of segments in adult males.
