Summary

Molecular & Morphological Evidence: The distinction is based on both molecular phylogeny (DNA analysis) and shell morphology.
Redescription of Two Species: Whittenia vermicula and W. gittenbergeri, previously in Opisthostoma, are reassigned to the new genus.
Endemic to Perak: Both species are endemic to limestone karsts in Kinta Valley, Perak, Malaysia.

Main Findings:

Unique Shell Character: Whittenia is characterized by an outer whorl around the discoid apex that is raised above the level of the apex, distinguishing it from Opisthostoma and Arinia.
Phylogenetic Placement: W. vermicula is more closely related to Arinia than Opisthostoma, though support for this relationship is not strong.
Conservation Implications: The discovery highlights the rich biodiversity of Malaysia's limestone karsts and emphasizes the need for their conservation, particularly in areas like Kinta Valley where these snails are endemic.

Etymology:
The genus is named after Dr. Tony Whitten, a prominent conservationist known for his work protecting limestone karsts in Southeast Asia.
