Describing new worms
, 21 Tachwedd 2012
Marine scientist Teresa Darbyshire has just re-discribed a new species of Polychaete (commonly called marine bristleworms). Unfortunately, a recent description of the new species, Dysponetus joeli (Olivier et al. 2012) used damaged specimens and errors were made.
This is because Polychaetes react notoriously badly to being handled roughly which is usually unavoidable with large marine surveys. Collected specimens are often in very bad condition by the time they are identified.
However, hand collected specimens by Amgueddfa Cymru - National Museum Wales from survey work done in 2009 in the Isles of Scilly were found to be the same species but in very good condition.
Using these specimens and comparing them with the original specimens from the Muséum National d’Histoire Naturelle Paris, enabled the errors to be corrected.
A re-description and revised species key have now been published - http://goo.gl/uAUqM.
