Yeah, I believe so. I kept a ‘Vietnamese Earth Tiger’ - as sold by a pet store, years ago. I identified it as Haplopelma vonwirthi at the time, which then became Cyriopagapus vonwirthi I believe, and is now considered a regional colour variant of Cyriopagapus minax if I understand correctly. Lovely spiders, mine was stunning!Mine is always underground. Is that the Vietnam Tiger?
