I think this is a Halgerda, but none of the illustrations in the Species List match my photo. HELP!
Locality: South Coast KwaZulu-Natal, South Africa. Shelly Beach (near Port Shepstone)- 36m

Dear Valda,
I know we are in unchartered waters here but I think this is a colour form of Hlagerda dichromis. I know it looks a bit different from the photos we already have on the site but with a bit more dark brown/black they would be quite like this.

H. dichromis was described from a single specimen so it is only your material that is giving us any indication of the colour range within the species. Any further colour variations would be interesting, especially internediates between this colout form and the earlier ones.

Best wishes,
Bill Rudman.
