Synonyms and other taxonomic changes
First described in 1888 or 1889 by Léon Abel Provancher as Eucerceris insignis. Karl Wilhelm Dalla Torre moved the species to Cerceris, which already had a species named insignis. Dalla Torre proposed the name Cerceris provancheri as a replacement, which- according to the rules at that time- was permanent. Even though it was moved back to Eucerceris, provancheri is still the correct name: the rules were later changed, but not for names already in existence.
Explanation of Names
provancheri is Latin for "of Provancher"
insignis is Latin for "remarkable"
