There are two very similar species that have shell green with a series of opaque white bands radiating along the margin Berthelinia schlumbergeri and B. limax. These two species have a Indo Pacific distribution... So very difficult to conclude...
Synonymous : (according Worms)
For Berthelinia schlumbergeri :
- No other name
For Berthelinia limax :
- Tamanovalva limax Kawaguti & Baba, 1959
Bibliographic data :
These little sacoglossan opisthobranchs were originally described as bivalves (pelecypods), based on fossil solitary shells, but in the late 1950's Kawaguti & Baba (1959) described the living animals. Some workers have divided the group into multiple genera, but many of the species apparently differ in only minor variations of shell morphology. Gosliner (1987) considers South African specimens of Berthelinia to be B. schlumbergeri
