Help identifying these slails

[Matuva]

I thought there were Physea, but these ones have a seal (a "door") I have circled in yellow, opposite the Physea which don't.

They are around 7 millimeters long, and were collected in pure freshwater (rainforest creek)

@Baccus may know?

I wish I could help. I am guessing that you wild collect?

They look a little like a snail that I have caught previously around here, but the ones I got tend to have a slightly longer spiral and I don't think they have a "door".

It is really hard to see in the pictures but was the "door" a full door or only a partial one? Does the snail when its on glass look like it has a distinct head or does it look like the mouth is all one part of the foot/ body? So far I am leaning towards a type of Physella.

Would this link to a snail site help? I would explore all its various photo and named species options.
