I have some problems identifying some snails of Thiaridae family.

I bought some snails labeled as Melonoides granifera fron a snail store in england. You can see it in the right side ot the follow picture.


This week I got from Germany some snail labeled as Thiara scabra... At first view, looks like M. granifera of the above picture but more large.
Following a pictures of the snails I got from Germany labeled as Thiara scabra.


What do you think??? Are both the same sp.???

Hi Xema,

I have three of the 4 snails above. I don't have the black one one the left (what sp is this? It looks interesting!). The snails I have are M. tuberculata, M. maculata and the last one I think it is the same as mine, ie M. granifera.
Some of my M. granifera are reaching 2cm long!

I did a search on T. scabra and found this:

So, I don;t think T. scabra is the same as M.granifera. From the google images above, I think you have M. granifera instead of T.scabra.

If you search using M. granifera you will get more photos looking like yours:

The black snails are exactly looking like the ones I have.
I was told they are Tarebia granifera.

I am quite confused, looking in to the site Conchology.be (http://www.conchology.be/en/availableshells/searchresultsgallery.php?family=THIARIDAE), watching Thiaridae family, I can see Melanoides genus seems to have relative narrow shells and Thiara has some specimen with relitive similar shell.

Thiara sp.

Melanoide granifera

Another shell collection of Thiaridae family. (http://members.aol.com/Mkohl1/thiarida.htm)

About my melanoides colecction... blacks one is M. maculata, but spotted and clear one are M. tuberculata.

Maybe we can share some snails...

I bought them labeled as Mahogany Trumpet Snail.

Maybe you can post a picture of your T. granifera...

Hi Xema,

I just have 1 blurry pic of these snails. My skill and equipment is not as well as yours. :cry:

Xema, are you sure that the black one is M. maculata? I thought the third one (counting from the left) without brown spots is M.maculata?

I never can be sure with this kind of classification... I know a malacologist, maybe he can help us.

Hello Xema,

this is my third try to give you an answere for your question.
Sorry for my bad englich - I hope youŽll understand me.

The name of the right snail of your first picture is Thiara winteri.
We had the same problems to indentify this one. So we sent a snail to "Humbold Unsiversity of Berlin".

In free nature the snails build up little spines. This looks very beautiful.
I can show you a picture if you want.
