A retired name, kept as a page because old books and old listings keep it alive: Dugesiella was folded into Aphonopelma decades ago, and everything that traded under it is a North American tarantula now filed there.
The animals behind the label are the familiar natives: slow, calm, arid, undemanding terrestrials with urticating hairs and lifespans measured in decades for females. The keeping is the standard Aphonopelma program in every respect.
The label survives in vintage literature, museum records, and the occasional listing transcribed from either, which gives this page its purpose as a translation stop: a Dugesiella offer describes an Aphonopelma, the old name adds no information and no value, and the current genus page is where the market actually lives.
