Rev. Chilena Ent. 1998,25:21 -44 LARVAE OF SOUTH AMERICAN ENTIMINI (COLEÓPTERA: CURCULIONIDAE), AND PHYLOGENETIC IMPLICATIONS OF CERTAIN CHARACTERS Adriana E. Marvaldi' ABSTRACT Larvae of 16 species of Entimini are described and illustrated, 10 of them for the first time. Larval descrip- tions or redescriptions are given for the South American genera: Cylydmrhinus Guérin, Entimus Germar, Malvinius Kuschel, Pororhynchus Schoenherr, Naupactus Dejean, and Platyaspistes Schoenherr. Larvae of species assigned to Naupactus and allied genera {Asynonychus Crotch, Atrichonotus Buchanan, and Eurymetopus Schoenherr) do not show differences at generic level. The larvae herein studied are compared with those known from other regions, and the taxonomic or phylogenetic implications of certain characters are discussed. Key words: Curculionidae, Entimini, larvae, morphology, systematics. RESUMEN Larvas de 16 especies de Entimini son descriptas e ilustradas, 10 de ellas por primera vez. Descripciones o redescripciones larvales se brindan para los géneros sudamericanos: Cylydwrhinus Guérin, Entimus Germar, Malvinius Kuschel, Pororhynchus Schoenherr, Naupactus Dejean y Platyaspistes Schoenherr. Larvas de especies asignadas ^Naupactus y géneros afines (Asynonychus Crotch, Atrichonotus Buchanan y Eurymetopus Schoenherr) no presentan diferencias a nivel genérico. Las larvas tratadas aquí son comparadas con las conocidas de otras regiones y se discuten las implicancias taxonómicas o filogenéticas de ciertos caracteres. Palabras claves: Curculionidae, Entimini, larvas, morfología, sistemática. INTRODUCTION Nearctic, or Australian regions. Contributions to weevil systematics based on larvae of South Ameri- The Entimini, as defined by Marvaldi (1997, can taxa have been contrastingly few and sporadic, 1998b), are the largest tribe of the subfamily despite the high diversity of Entimini present in this Entiminae, comprising about 1115 genera and región (Wibmer & O'Brien, 1986).
