[Annelida] Paradoneis

Hey!  I had troubles identifying what I thought was Paradoneis lyra from
Tampa Bay, FL, USA.  I came across the following article, which you will
want to check out.  This article follows the opinion of Strelzov (1973)
which synonymizes Paradoneis and Paraonides with Cirrophorus.  This
synonymization appears to be controversial and I am not sure which is
commonly accepted amongst the polychaete community.  Maybe others
belonging to this forum will want to comment on this.  Table 1 in
McLelland and Gaston (1994) helped me sort out our local species and it
may help you as well.  The local specimens that I have fit Cirrophorus
lyra, but I agree with Geoff on the fact that this species may not be as
widely distributed as previously thought.  Here are those citations:


McLelland, J. A. & G. R. Gaston.  1994.  Two new species of Cirrophorus
(Polychaeta: Paraonidae) form the northern Gulf of Mexico.  Proceedings
of the Biological Society of Washington 107 (3): 524-531.

Good luck!

I seem to be confused.  A Paradoneis is very important to some work in a

southeast New Zealand intertidal inlet.  I would normally have called it

Paradoneis lyra (Southern 1914).  I just read a paper (citation below) 

with new descriptions including a new Paradoneis eliasoni.  While the 

paper is well illustrated it seems to be missing some discussion of the 

characters needed to resolve some splits (or I may be missing some 

convention).  Paradoneis eliasoni appears to be described from 2 

anterior fragments and an 'almost complete' worm.  I don't have a copy 

of the original Paradoneis lyra description.  According to Table 3 in 

the publication, P. eliasoni has acicular neurochaetae in the far 

posterior segments.  I grabbed some of our 2000+ specimens and they all 

have them.  The table includes a strike rather than a question mark  (no

mention?) of these for P. lyra (Southern 1914).   Both type localities 

are from the other side of the planet, P. lyra capensis (Day 1955) is 

from South Africa, but the pre-branchial notopodial lobes are present in

our specimens, but Day may not have had specimens this large.  Any


My diagnosis of our beast (made before seeing the paper): Conical 

prostomium slightly longer than wide, slit nuchal organs, branchiae 

start on chaetiger 4 and continue for 11-12 chaetigers [a little shorter

than segment width), no eyes, no median antenna/scar, small notopodial 

lobes present on pre-branchial chaetigers larger in branchial chaetiger 

smaller in postbranchial chaetigers then very proporitionally large in 

extreme posterior, earliest observed forked chaetae on chaetiger 3 only 

one observed in each notopodium, posterior chaetigers with stout 

acicular chaetae (one each neuropodium) which is weakly hooked, 3 

pygidial cirri.  [I didn't note the capillary numbers]
