      Description

      With the new backbone and updated processing we see a drastically different map with many spider occurrences showing up in the Indian and Pacific Ocean: http://mdoering.github.io/nub-browser/app/#/taxon/1496

      Verify these are correct

          New occurrences in the Indian ocean seem to be all from the genus Heteropoda which is indeed a spider genus:
          http://www.gbif-uat.org/occurrence/search?TAXON_KEY=1496&GEOMETRY=64.5%20-11.7,64.5%20-25.5,95.5%20-25.5,95.5%20-11.7,64.5%20-11.7

          For example http://www.gbif-uat.org/occurrence/112952315/verbatim sampled in 0-200m depth

          http://www.wsc.nmbe.ch/genus/3115/Heteropoda
          https://en.wikipedia.org/wiki/Heteropoda

          I cannot find evidence for them to appear in oceans, but at least our interpretation of the surprising records seems to be correct

          Damn, I will see how we can best add that group to the backbone. With no further classification given the records should then remain unmatched.

          Perhaps we need an issue flag for occurrences that have a scientificName without an accompanying classification? Looks like a number of data providers assume that GBIF knows the taxonomic context of an occurrence without providing any obvious way to determine that.

          Apparently nowadays treated as a synonym of the superfamily Pterotracheoidea:
          https://en.wikipedia.org/wiki/Pterotracheoidea

          Yet another example of a non Linnean higher taxon missing in our backbone. I would hope at some point we can add non Linnean ranks to the backbone, see POR-2781

          I will add Heteropoda as a synonym of the gastropod order Littorinimorpha which is the closest we have in our backbone:

          Such a flag would be good indeed, Rod.
          And we should probably start curating datasets a little and assign them a taxonomic context in our registry if possible. Often they are restricted to a kingdom or even lower

          as the records dont come with a rank and the order Heteropoda is considered a synonym it still matches the spider genus
