Other Common Names
The use of the common name “cypress leaf beetle” for Systena marginalis should be dropped since this species appears to be associated with many different tree species. In fact, its association with cypress (Taxodium spp.) needs confirmation, there being a good chance that such reports may be based on the misidentifications of a similar species, S. plicata Blatchley that has a genuine association with cypress.
Synonyms and other taxonomic changes
Systena marginalis (Illiger)
Orig. Comb: Haltica marginalis Illiger, 1807
Systena plicata Blatchley is similar in size and color, but has a distinct lateral fold (ridge) along the margin of each elytron (lacking in S. marginalis). Systena corni is also similar in general appearance but differs in being less strongly marked (and in male genitalia) and has a genuine association with flowering dogwood (Cornus florida).
