Synonyms and other taxonomic changes
Numbers
Eucanthus alutaceus Cartwright 1944 - Florida, dorsum dull
Eucanthus greeni Robinson 1948 - Western US
Eucanthus impressus Howden 1964 - Generally distributed - at least Indiana, Virginia, Florida, Texas and Nebraska. Very similar to E. lazarus, may often go unrecognized.
Eucanthus lazarus (Fabricius 1775) - Generally distributed
Eucanthus subtropicus Howden 1955 - Southern US.
E. subtropicus is not listed in
Nomina Nearctica, since it was originally proposed as a subspecies of
E. lazarus and Nomina treated all subspecies as synonyms (synonyms aren't included in the on-line version of the list). This was later elevated to species rank by Howden 1964 - an action evidently overlooked by NIN. I'll assume that this is also why [as of 12/29/06], the
Wisconsin website still shows
Eucanthus lazarus lazarus.
