Hi polychaete lovers,
I'm currently fighting with a few individuals from the same species very
likely from the genus Nothria (Malmgren, 1866) but base on the keys I'm
using (i.e. Synopsis of the British Fauna n°32, Eunicida), I can't come
up with something satisfacory. Everything match with Nothria conchylega
(Sars, 1835) except the stout hooked chaeta from chaetiger 1 & 2 that
are missing and the occurrence of clearly bidendate hooked chaeta
instead. Speciment have been collected in South Brittany, France and I
do have "true" specimen of Nothria conchylega (Sars, 1835) from that
region with the stout hooked chaeta from chaetiger 1 & 2.
So, what is wrong with me? Does anyone have a better key with a better
description of this genus to provide? Have anyone face this problem yet?
Thanks for your help,
Stan.
