Macrophthalmus

Hi there! I went to Lantau Island and took some of Macrophthalmus photos in August. Please help me to ID.
Those are taken in tidal flat area.

No.1 I think this is a Macrophthalmus convexus.



No.2 ???



No.3 I think this is a Macrophthalmus tomentosus. Because it is covered with small hair.



No.4 Sorry it's not clear for ID. But if anybody can ID this, let me know.



Thank you!

No.1 agree M. convexus
No.2 you can consider M. definitus
No.3 Not sure, it can also be  M. erato or something else, better if you have a clear photo showing the anterolateral teeth.
No.4 don't know...

Reply #2 nelsonabc's post

Thank you for your reply nelsonabc.
I compared No2. with M. definitsus. I could see only one photo from internet. But their grooves on the shell and anterolateral teeth look very similar.
I want to compare No.3 with M. erato, but it's really hard to get any information of them from internet. If possible, could you provide me any info about M. erato?
Here's a bigger photo of No.3. It has taken by iPhone and picture is not good enough though.

Appreciate your help!
