[API-users] typeSpecimens query for species is broken

According to the docs I should be able to get the type specimens for a species using: http://api.gbif.org/v1/species/5231190/typeSpecimens (the example given on http://www.gbif.org/developer/species ) But this returns {"offset":0,"limit":20,"endOfRecords":true,"results":[]} This species has A LOT of types, see http://www.gbif.org/species/5231190, so something seems amiss...
