REMARK This species looks similar to Purex formosus , differing only by the shape of the forceps. In particular they both have the occiput undepressed, which is quite unusual among Purex species. Given that important variation exist in forceps shape in some species of Purex ( Brindle 1977 ) , P. formosus and P. parvicollis might represent two forms of the same species. This point needs further studies.
