<i>Hemilamprops ultimaespei</i> Zimmer, 1921 <p> <i>Hemilamprops ultimaespei</i> Zimmer, 1921: 3 –5, fig. 1–3.</p> <p> <i>Hemilamprops lotusae</i> Băcescu, 1969: 168 –171, fig. 4.— Mühlenhardt-Siegel, 2003: 125 –126. [New synonymy]</p> <p> <b>Type material</b>. LEcTOTYPE: OVIgEROUS fEMALE, SMNH TYPE-817 (PART), TERRE dU FEU, ULTIMA ESPERANZA, SOUTHERN CHILE, 50°30’S, 74°W. PARALEcTOTYPE: SUbAdULT fEMALE, SMNH TYPE-817 (PART), cOLLEcTEd WITH HOLOTYPE.</p> <p> <b>Remarks</b>. ZIMMER (1921) dId NOT dESIgNATE A HOLOTYPE fOR <i>H. ultimaespei</i>, SO HIS TWO TYPE SPEcIMENS ARE SYNTYPES. THE TYPE dEScRIPTION ANd fIgURES ARE bASEd ENTIRELY ON THE OVIgEROUS fEMALE SPEcIMEN, WHIcH IS HEREbY dEcLAREd THE LEcTOTYPE. THE SUbAdULT fEMALE SPEcIMEN WAS MENTIONEd bRIEfLY IN THE TEXT Of THE ORIgINAL dEScRIPTION AS YOUNgER ANd IN POOR SHAPE, ANd bEcOMES THE PARALEcTOTYPE. MüHLENHARdT-SIEgEL (2003) SUggESTEd THAT A LATERAL RIdgE ON THE cARAPAcE WAS PRObAbLY PRESENT IN <i>H. ultimaespei</i>, bUT OVERLOOKEd bY ZIMMER (1921). UPON cLOSE INSPEcTION, INcLUdINg TEMPORARY STAININg WITH cHLORAZOLE bLAcK E IN ETHANOL, NEITHER Of THE TYPE SPEcIMENS Of <i>H. ultimaespei</i> HAS ANY TRAcE Of A LATERAL RIdgE ON THE cARAPAcE.</p> <p> THE IdENTITY Of <i>H. lotusae</i> BăcEScU, 1969, ANOTHER SOUTHWESTERN ATLANTIc SPEcIES, HAS bEEN AMbIgUOUS SINcE IT WAS fIRST dEScRIbEd. THE ORIgINAL TYPE MATERIAL Of <i>H. lotusae</i> (OVIgEROUS fEMALE HOLOTYPE, GAM 112; 3 OVIgEROUS fEMALE PARATYPES, GAM 113; GOLfE dE SAINT ANdREWS, ARgENTINA, 41°16’S, 60°03’W) IS NOW LOST, AccORdINg TO I. PETREScU, cURATOR Of cUMAcEANS AT THE GAM (cITEd IN MüHLENHARdT-SIEgEL 2003, ANd PERS. cOMM). THE ORIgINAL dEScRIPTION Of <i>H. lotusae</i> WAS ENTIRELY INAdEqUATE TO dIScRIMINATE THIS SPEcIES fROM OTHER SPEcIES Of <i>Hemilamprops</i>. THE SOLE cHARAcTER dISTINgUISHINg <i>H. lotusae</i> fROM <i>H. ultimaespei</i> IN THE ORIgINAL dEScRIPTION WAS THE POSSESSION Of ONE PAIR Of LATERAL SETAE ON THE TELSON RATHER THAN THREE PAIRS; HOWEVER, THERE ARE AT LEAST TWO SPEcIES Of <i>Hemilamprops</i> KNOWN IN WHIcH THE NUMbER Of LATERAL SETAE ON THE TELSON VARIES fROM 2–3 WITHIN POPULATIONS (GERKEN 2005; MüHLENHARdT-SIEgEL 2003), ANd EVEN ON THE SAME INdIVIdUAL (GERKEN 2005), THUS THIS cHARAcTERISTIc cANNOT bE cONSIdEREd dIAgNOSTIc. MüHLENHARdT-SIEgEL (2003) ALREAdY SUggESTEd THAT <i>H. lotusae</i> MAY bE A SYNONYM Of <i>H. ultimaespei.</i> GIVEN THE RELATIVELY cLOSE LOcALITIES Of cOLLEcTION bETWEEN <i>H. lotusae</i> ANd <i>H. ultimaespei</i> ANd THE MORPHOLOgIcAL SIMILARITIES NOTEd bY BăcEScU (1969) ANd MüHLENHARdT-SIEgEL (2003), THE IdENTITY Of <i>H. lotusae</i> REqUIRES RESOLUTION. THUS, TO fIX THE IdENTITY Of <i>H. lotusae</i>, THE LEcTOTYPE Of <i>H. ultimaespei</i> IS HEREbY dESIgNATEd AS THE SIMULTANEOUS NEOTYPE Of <i>H. lotusae</i>, MAKINg <i>H. lotusae</i> A jUNIOR ObjEcTIVE SYNONYM Of <i>H. ultimaespei</i>.</p>Published as part of <i>Gerken, Sarah & Haye, Pilar A., 2018, Hemilamprops chilensis sp. nov.
