Pachycordyle navis ( Millard, 1959) Introduced (= Clavopsella navis )

Pachycordyle navis is an example of an exotic species first described from the region to which it was introduced. Schuchert (2004) placed Millard’s Rhizorhagium navis (as Clavopsella navis in her 1975 monograph) in the genus Pachycordyle and recorded a wide European (including Mediterranean and Black Sea) distribution. It was found in 1958 in South Africa on the hull of a ship which had never left Table Bay ( Millard 1975). Although not recorded since 1958, it has also not been searched for since then, hence there is no reason to presume that it is not still present.
