Haworthia attenuata is regarded as a synonym for Haworthiopsis attenuata by some (http://www.plantsoftheworldonline.org/taxon/urn:lsid:ipni.org:names:535997-1), while others claim Haworthia attenuata to be an old name of Haworthiopsis attentuata. Either way Haworthiopsis attentuata seems to be the preferred name. This taxon is therefore either a duplicate (as Haworthiopsis attentuata already exists here on iNaturalist: https://www.inaturalist.org/taxa/577654-Haworthiopsis-attenuata) or it is no longer used and should be sunk into Haworthiopsis attenuata.
