I had a colony of Lateralis before and even in the past they are called and sold as B. Lateralis here in the Philippines.
Then I searched on Google "Shelfordella Tartara" and to my surprise it refers to the same specie.
I'm amazed that it has two scientific names.
I don't know maybe its like some tarantulas which has an old name and then changed to a new one?
It is sometimes confusing.
Well, anyways they are fast breeders and would surely provide you lots of feeders for your other pets.
