Here are some photos of Aldisa smaragdina. The photos of Aldisa smaragdina in Alma Sánchez's message are actually of A. banyulensis. I have sent photos of the tubercles in a separate message.
To help compare this species with Aldisa banyulensis here are some measurable details which differ between the two species.

These photos of A. smaragdina and the photos you have sent separately of Aldisa banyulensis are helpful in differentiating between these two species. However I still would be interested to know about the differences between A. smaragdina and A. binotata.
