Perhaps you should try some spelling variations:
"monotypic taxon" » "genotypic taxon", "monotypic talon", "monotypic axon", "monotypic faxon"
"monotypic faron" » "genotypic faron", "monotypic faroni", "monotypic aaron", "monotypic baron"
"monotypic saxon" » "genotypic saxon", "monotypic salon", "monotypic saxo"
"monotypic aon" » "genotypic 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 faron") OR ("monotypic saxon"))))) OR ("monotypic aon"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"monotypic taxon\") OR (((\"monotypic faron\") OR (\"monotypic saxon\"))))) OR (\"monotypic aon\"))".
• Removing quotes may allow a broader search: (((( monotypic taxon ) OR ((( monotypic faron ) OR ( monotypic saxon ))))) OR ( monotypic aon )).
• Adding a wildcard symbol may retrieve word variants: (((("monotypic taxon") OR ((("monotypic faron") OR ("monotypic saxon"))))) OR ("monotypic aon"))*.
