INTRODUCTION Ourprevious listfromArgentina (MUZON &VONELLENRIEDER, 1998) included261 species, bothdescribedandundescribed.Although only seven new species occurringinArgentinahavebeendescribedsincethen,severalnamesmen- tionedearliercorrespond tooldrecords based onmisidentifiedspecimens. Nu- merous newrecords havebeenfoundduring thelastfew years,andmanygenera ofourfaunahavebeen recentlyrevised making itnecessaryto update thelist in ordertoreflectthecurrent namechanges andsynonymies. All species mentionedin thecurrent listing areeitherrepresented ina collec- tionandwereexaminedby us, ortheiroccurrence inArgentina hasbeenreliably demonstrated. 56 N.vonEllenrieder &J.Muzon SPECIES TO BE DELETEDFROM THE ARGENTINE CHECKLIST Thepreviousrecords ofthefollowing27specieswereeither based onmisidentifications ormisla- beledmaterial,orhavebeenshown torepresentsynonyms ofotherspecies: Hetaerinacajadominula HageninSelys, 1853 FRASER (1948)recorded thisspecies fromArgentinabased onamale fromMisiones province.

UPDATED CHECKLIST Our currentlistincludes256species describedupto December2006.Although therateof descriptionof newspecies occurring inArgentina hasbeenlowduring thelastcentury,withoverhalfofitsodonatesalready describedatthebeginning ofthe 1900’s(Figs 1-2),thereare stillnewspecies being discovered, ofwhichwe currently knowof 14,bringing thetotalofknown species to271. A major development over the lastfew decades hasbeen anincrease in the knowledge ofthe larvalstage,which is crucial forthe development ofregional programs for conservationand managementof wetlands. Approximately two thirdsoftheknownlarvaehavebeendescribedduringthelast25 years,andabout halfofthemduring thelast8 years(Fig. 2).Atpresent, the lastlarvalinstar of approximately 53%oftheArgentine species isknown(Fig. 2).

The best known areas correspond to BuenosAiresprovince, Patagonia (southern halfofthecountry Nto Mendoza andLaPampa), NE Argentina, including Misiones, CorrientesandEntre Rios provinces, andNW Argentina, encompassing Jujuy, Saltaand Tucumanprov- inces.Thereare stillseveralareas thathavebeenvery poorlysampled, including theprovinces ofFormosa, Chaco, LaPampa andSanJuan,andsomeothersthat were sampled only partially, such as Catamarca, LaRioja, San Luis, Cordoba, Santiago delEsteroandSantaFe provinces (Fig. 3).
