The specific epithet 'crataegi' derives from Crataegus (hawthorn), suggesting a possible historical or suspected association with hawthorn plants, though this relationship has not been confirmed in published literature.
Taxonomic Note
The Pseudanthonomus is taxonomically challenging, with many poorly characterized in terms of biology and associations. P. crataegi exemplifies this pattern, with minimal published information beyond original description and basic distribution records.
