Quite some time ago the Dublin Core type vocabulary and Darwin Core type vocabulary were relegated to control distinct terms in Darwin Core. This meant that Dublin Core type values were recommended only for dcterms:type and not for basisOfRecord. Thus, a record of a camera trap image would have dcterms:type=StillImage and basisOfRecord=MachineObservation. Though the Darwin Core type vocabulary was deprecated, the recommendation (and the strength of it) remains. Following the recommendation (which GBIF's IPT implements and enforces), non-standard values are not allowed. 

My recommendation for the non-standard basisOfRecord values is to change to the following combinations:

'literatureObservation' - dcterms:type=Text, basisOfRecord=HumanObservation

'literature' - dcterms:type=Text basisOfRecord=Occurrence (if you can't be more specific)

'fieldObservation' - dcterms:type=Event, basisOfRecord=HumanObservation

'unknown' - dcterms:type=null, basisOfRecord=Occurrence

fieldObservation probably maps sanely onto HumanObservation.

unknown maps sanely onto Occurrence "NOTE: this value is ambiguous and
hence should only be used when the when the resource type is unknown"

This type vocabulary doesn't include a sane type for data derived from
the literature.  This type vocabulary claims to extend the Dublin Core
type vocabulary, so data sourced from the literature should probably be
able to map to Text http://purl.org/dc/dcmitype/Text.  Whether IPT,
on a technical level, treats the DarwinCore type vocabulary as an
extension of the DublinCore type vocabulary and treats values from
dcmitype as valid is another question.
