Hello all.. another micro mollusc collected from trash along the east coast of India. Can anyone identify the species please?
I do not know Indian Ocean species, but this is definitely in the Eulimidae family. If it were an Atlantic specimen I would say the genus is Eulima or possibly Melanella.
Deepak:
Could you please document a few more specimens? Looks like some juvenile specimens showing affinity with genus Oxymeris, but I am not very sure.

Dear Deepak i agree with G. Lynn Wingard the genus could be Eulima, Eulimidae family
Dear Dr Wingard and Dr Jorge,
this specimen looks closest to Eulima panamensis (Bartsch, 1917) - Eulimidae. The other closest ones include Eulima bilineata, E. glabra and Hemiliostraca metcalfei. All of them have characteristic brown markings but E. panamensis has prominent ending brown nodes at the end of the markings (like a computer chip node). This is matching with the image posted.
Dear Dr Syed,
This is a very rare specimen and Eulimidae is poorly studied in India. Terebrids (Oxymeris, Terebra etc.) have short aperture and there are more whorls. Eulimids have smoother shells. Most of them are ectoparasitic whereas terebrids have venom for prey capture. I quite agree with your view on the appearance of a juvenile terebrid. But this is definitely Eulimid as pointed out by other colleagues.
Thank you all!
Hi Deepak,
of course eulimidae...maybe Dr Warén ([email protected]) may help you.
Deepak:
If the specimen looks closest to Eulima panamensis, then should this be the first report from Indian waters?

Yes Dr Syed, it seems so.. but I have to go through old reports (ceylon fisheries 1906, Herdman etc.). to authenticate.
3 species under this genus have been documented in Indian waters already viz..
Eulima balteata (A. Adams, 1864), E. bivittata (H. Adams & A. Adams, 1853) and E. recurva Boettger, 1893.

Initially transport has been anthropic but from what I see the species has developed characters, as the brown peristome and the deep line of growth, this could have affected on his DNA, and now it is a different species….. maybe a new species . Roberto.
Dear Roberto yes!, that's what Dr Warner has informed too. But unfortunately only the shell is available. Now it is Eulima (s.str) sp.

Deepak
Definitely a species of the genus Eulima (Family Eulimidae).
Several species of this genus presents this kind of color pattern, like some species mentioned before by other colleagues and Eulima bifasciata d'Orbigny, 1841 (from Western Atlantic).
Species of Hemiliostraca also have similar color pattern in many species, but the area of the columella is usually flattened. There are other diagnostic features of this genus.
I do not know too much about the fauna of Eulimidae from the Pacific and Indian Oceans. My research focus on the Atlantic eulimids.
I agree that Dr. Anders Wáren can help you.
Anyway, if you need bibliographies about the family I have a plenty of them.
Best wishes,
Leonardo
Dear Dr Leonarado,
thank your for your information and also for the willingness to share bibliographies! Would be happy if you can mail me the soft copies for family EULIMIDAE..you can please mail me at [email protected], [email protected].
Thank you once again

@ Deepak , this link contains many varity of gastropods. hope this will help you http://www.stromboidea.de/?n=People.GijsKronenberg
Definitely a Eulima of some sort - beautiful specimen! I hope you will be putting together a compilation of all your great finds.
Hi Dr. Lynn,
yes. Actually as a team we have planned to put together all the new finds that we have from SE coast of India into a paper. The specimen is Eulima cf panamensis. I have another variant in my collection too. Will definitely share the progress of this work!
Thank you so much for the encouragement
Best regards
Deepak
Glad to hear you will be putting a paper together. Please keep us posted!
