Synonyms and other taxonomic changes
First described in 1758 by Linnaeus as Coccinella 14-guttata.
Since Linnaeus used an abbreviation, there is disagreement as to whether quatuordecimguttata or quattuordecimguttata is the correct spelling. Quattuordecim for 14 is correct according to Latin dictionaries, but quatuordecim is the spelling Linnaeus used elsewhere in the same description.
Calvia quatuordecimguttata
