Abstract

The present paper records changes in the reported distribution and abundance of terrestrial nemerteans during the last 30 years. New records are reported from the Isles of Scilly, Bermuda and New Zealand of species previously only known elsewhere. Human activity, especially the increased importation and exportation of plants between countries, has probably led to terrestrial nemerteans, as well as other organisms, becoming introduced into many new localities. However, the conservation outlook is not hopeful because of a global loss of appropriate habitat, particularly forests. Today three species (Geonemertes rodericana Gulliver, 1879, Pantinonemertes agricola Willemoes-Suhm, 1874 and Antiponemertes allisonae Moore, 1973) are feared to be extinct, and none of the extant species seem to be as abundant as they once were. Behavioural changes in Antiponemertes pantini (Southgate, 1954) under arid conditions may be associated with heavy gregarine infestations.

Note added in proof Subsequent to our paper being accepted for publication, Dr Wolfgang Sterrer has kindly sent us the details of where on Bermuda he found the Geonemertes pelaensis specimens, together with the comments that “...I collected this beast, which in my 29 years in Bermuda I had never seen before, at three locations...within two weeks...Simultaneously, it seems, Bermuda's only terrestrial flatworm, Bipalium kewense, became much less common. Is it possible the nemertean feeds on the flatworm?” The locations where the Geonemertes pelaensis were found on Bermuda, together with theirMuseum reference numbers, are: 11 July 1998, under a stone in the Botanical Gardens at Paget: BAMZ 1998.168.022 17 July 1998, between empty flower pots, Aquarium grounds in Flatts: BAMZ 1998.169.005 25 July 1998, under a concrete block in a garden (12 individuals), Narrows Lane, St. David's: BAMZ 1998.169.009Google Scholar
