Abstract

Cyclocephala pygidialis Joly new species from Venezuela is described and compar-ative redescriptions of C hardyi Endrodi and C castanea (Olivier) are presented Di-agnostic characters are illustrated and full references for each species are given

Resumen

Se describe Cyclocephala pygidialis nueva especie de Venezuela y se presentan re-descripciones comparativas de C hardyi Endrodi y C castanea (Olivier) Se ilustranalgunos de los caracteres diagnosticos y se incluyen las referencias completas de cadaespecie

When Endrodi (1975) described Cyclocephala hardyi he compared it withC castanea (Olivier 1789) a species which it closely resembles and statedlsquolsquoDie aussereen Eigeschaften der neuen Art stimmen mit der Diagnose die ichin meiner Monographie der Dynastinae I fur C castanearsquorsquo (The externalcharacters of the new species completely agree with the diagnosis of C cas-tanea in my Monograph of the Dynastinae I ) and lsquolsquoleglidich die Formder Parameren kann (zur Zeit) die beiden Arten trennesrsquorsquo (only the shape ofthe parameres can (up to now) separate the two species) In his keys (Endrodi1985) he said that lsquolsquoC hardyi Endrodi is very similar to previous species [Ccastanea] externally impossible to separate but aedoeagus widely differ-ent rsquorsquo Prance and Arias (1975) and Lachaume (1992) repeated the same

While studying the Venezuelan species of Cyclocephala I found two spe-cies one of them C castanea and the other a new species both closely relatedto C hardyi The three species are similar but contrary to the statements ofEndrodi (1975 1985) all three species can be separated easily based on ex-ternal characters I here describe the new species and provide comparativeredescriptions of C castanea and C hardyi including some characters notmentioned by Endrodi

Abstract

Cyclocephala pygidialis Joly new species from Venezuela is described and compar-ative redescriptions of C hardyi Endrodi and C castanea (Olivier) are presented Di-agnostic characters are illustrated and full references for each species are given

Resumen

Se describe Cyclocephala pygidialis nueva especie de Venezuela y se presentan re-descripciones comparativas de C hardyi Endrodi y C castanea (Olivier) Se ilustranalgunos de los caracteres diagnosticos y se incluyen las referencias completas de cadaespecie

When Endrodi (1975) described Cyclocephala hardyi he compared it withC castanea (Olivier 1789) a species which it closely resembles and statedlsquolsquoDie aussereen Eigeschaften der neuen Art stimmen mit der Diagnose die ichin meiner Monographie der Dynastinae I fur C castanearsquorsquo (The externalcharacters of the new species completely agree with the diagnosis of C cas-tanea in my Monograph of the Dynastinae I ) and lsquolsquoleglidich die Formder Parameren kann (zur Zeit) die beiden Arten trennesrsquorsquo (only the shape ofthe parameres can (up to now) separate the two species) In his keys (Endrodi1985) he said that lsquolsquoC hardyi Endrodi is very similar to previous species [Ccastanea] externally impossible to separate but aedoeagus widely differ-ent rsquorsquo Prance and Arias (1975) and Lachaume (1992) repeated the same

While studying the Venezuelan species of Cyclocephala I found two spe-cies one of them C castanea and the other a new species both closely relatedto C hardyi The three species are similar but contrary to the statements ofEndrodi (1975 1985) all three species can be separated easily based on ex-ternal characters I here describe the new species and provide comparativeredescriptions of C castanea and C hardyi including some characters notmentioned by Endrodi

The specimens studied are deposited in the following collections AMNHAmerican Museum of Natural History New York USA CMNC CanadianMuseum of Nature Ottawa Canada MHNLS Museo de Historia Natural LaSalle Caracas Venezuela NMNH National Museum of Natural HistorySmithsonian Institution Washington USA MIZA Museo del Instituto deZoologıa Agrıcola lsquolsquoFrancisco Fernandez Yepezrsquorsquo Maracay VenezuelaMNHN Museum National drsquoHistoire Naturelle Paris France UNSM Uni-versity of Nebraska State Museum Lincoln Nebraska USA
