TYPE lOCAlITY: “ MICHIgAN ” [ HERE RESTRICTEd TO SOUTHERN MICHIgAN, USA] [ FMNH].

GROTE dESCRIbEd marginalis bASEd ON AN UNSPECIfIEd NUmbER Of SYNTYPES fROm MICHIgAN, bUT THE COllECTOR Of THE TYPE mATERIAl IS UNKNOWN ANd A SPECIfIC lOCAlITY IS NOT gIVEN. THE mOST PRObAblE PROVENANCE IS SOUTHERN MICHIgAN, WHERE SEVERAl COllECTORS RESIdEd IN THE mId TO lATE 1800S, WHEREAS NORTHERN MICHIgAN’S LEPIdOPTERA REmAINEd VERY POORlY KNOWN ( NEWCOmb 1913). A PUTATIVE TYPE SPECImEN Of marginalis IN FMNH WAS EXAmINEd. IT REPRESENTS THE SUmmER bROOd fORm Of H. diffinis WITH A dENTATE INNER bORdER Of THE fOREWINg mARgINAl bANd, CONSISTENT WITH THE ORIgINAl dESCRIPTION. THE dENTATE mARgINAl bANd ANd THE SmOOTHER, SHORTER VESTITURE OCCUR ONlY IN SUmmER bROOd INdIVIdUAlS. THE SmAllER SIZE (44 mm WINgSPAN), NEARlY COmPlETElY dARK AbdOmINAl SEgmENTS 4 ANd 5 ARE CONSISTENT WITH H. diffinis , NOT aethra . HOWEVER, Hemaris aethra AlmOST CERTAINlY OCCURS IN MICHIgAN ANd AS THE IdENTITY ANd lOCATION Of OTHER POTENTIAl SYNTYPES Of marginalis IS UNKNOWN, THE fOllOWINg SPECImEN HERE IS dESIgNATEd AS lectotype:
