Hi There! I went to Lantau Island and took some of Onchidiidae photos in August. Please help me to ID.
I guess I saw 4 species there.
No.1 to No.3 were found in the place covered with mud and man head sized rocks. And it was an estuary area.
No.4 was found in Mangrove forest.


No.1 I think it's Platevindex mortoni.



No.2



No.3



No.4



Thank you!
