Identification
A relatively small species with Cornish male specimens between 10 to 10.5 mm in length. It is very similar in appearance to, and often occurs with, Polydesmus asthenestatus (a slightly smaller species).
The two species are readily distinguished from each other (and from Brachydesmus superus and other Polydesmus species) by the shape of the male gonopods, which are figured in Gregory (2023).
