through even more in-depth studies by lerche et al., we now know that "d. viridis" is actually a heterogenous group and can be split into different species such as "d. minuta", "d. parva", "d. media", and "d. euchlora", though these groups are often grouped into one and called "d. viridis". "d. salina" is now recognized as its own species and will soon become a very important one for biotechnological applications.
