Perhaps you should try some spelling variations:
"monotypic taxon" » "genotypic taxon", "monotypic talon", "monotypic saxon", "monotypic faxon", "monotypic tsaxon", "monotypic tfaxon", "monotypic taon"
"monotypic saon" » "genotypic saon", "monotypic salon", "monotypic saxon", "monotypic sajon"
"monotypic saxo" » "genotypic saxo", "monotypic sao", "monotypic sexo", "monotypic sano"
"monotypic axon" » "genotypic axon", "monotypic saxon", "monotypic faxon", "monotypic aon"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("monotypic taxon") OR ((("monotypic saon") OR ("monotypic saxo"))))) OR ("monotypic axon"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"monotypic taxon\") OR (((\"monotypic saon\") OR (\"monotypic saxo\"))))) OR (\"monotypic axon\"))".
• Removing quotes may allow a broader search: (((( monotypic taxon ) OR ((( monotypic saon ) OR ( monotypic saxo ))))) OR ( monotypic axon )).
• Adding a wildcard symbol may retrieve word variants: (((("monotypic taxon") OR ((("monotypic saon") OR ("monotypic saxo"))))) OR ("monotypic axon"))*.
