I've found MolluscaBase to be a pretty good guide to molluscan taxonomy. Unless there's a very recent defnitive study that disagrees, I'd go with MolluscaBase.

I have two Philippine land shells, portei and turbinoides. Are they Helicostyla or Helicobulinus? Years ago when I obtained them,  they were Helicostyla. In a 2022 publication they were Helicobulinus. I may have to verify all my Philippine shells. MolluscaBase has them as Helicostyla. Any help would be appreciated.

Best regards,
