Melopoeus sp. 'Bach Ma', formerly Cyriopagopus sp. 'Bach Ma' (Bach Ma earth tiger tarantula) 1"Melopoeus sp. 'Bach Ma' is a medium sized, undescribed species originally collected around Bch M National Park in Vietnam. Due to the presence of long white setae on the retrolateral cheliceral surface, a defining trait of the schmidti species group, it most likely belongs to that group. Like the other species in the schmidti group, they are fossorial species.
