Lasiodora spp. is a mess in pet trade. Lots of individuals that look alike were sold as L. parahybana, L. striatipes, L. klugi.
Tbh, its quite impossible to id or confirm these pet trade individuals.
The better thing you do is label it as it was sold to you and keep it that way. And if you dont trust your dealer and/or cant get any confirmation about the species, dont breed it with others, that you will avoid hybridism.
