------Species composition and distribution patterns of the Argentinian Aeshnidae (Odonata: Anisoptera)

von ELLENRIEDER, Natalia Instituto de Limnologia "Dr. Raul A. Ringuelet", C.C. 712, 1900 La Plata, Argentina; e-mail: [email protected]

• ABSTRACT. Ten genera and 27 species of Aeshnidae are recorded from Ar­ gentina: For each species a synonymyc list and distribution data are provided, as well as diagnostic keys for adults and known larvae. Distribution data per biogeographic province in Argentina are compared through cluster analysis. Specific and generic distribution patterns show that the richest areas are those of the subtropical forests encompassed by the Paranaense and Yungas bio­ geographic provinces, and that there are no Subantarctic endemics within Aeshnidae. Cluster analysis and complementarity values show that the Aeshnidae assemblage of the Monte biogeographic province is more closely related to that of Prepuna, Patagonian and Subantarctic provinces than to that of the Guyano-Brazilian provinces, supporting the existence of an Andean--Patagonian domain as proposed by Ringuelet.

• RESUMEN. Composicion especifica y patrones de distribucion de Aeshnidae argentinos (Odonata: Anisoptera). Se registran 10 generos y 27 especies de Aeshnidae para la Argentina; para cada especie se proporciona una lista sino nimica y datos de distribucion, asi como claves diagnosticas para adultos y larvas descriptas. Los datos de distribucion por provincia biogeografica en la Argentina son comparados mediante anal isis de agrupamientos. Los patrones de distribucion de especies y generos muestran que las areas de mayor rique­ za corresponden a las selvas subtropicales de las provincias biogeograficas Paranense y Yungas, y que no existen endemismos Subantarticos entre las Aeshnidae. EI anal isis de agrupamientos y los valores de complementariedad evidencian que la asociacion de Aeshnidae de la provincia biogeografica del Monte es mas similar a la de las provincias de la Prepuna, Patagonica y Su­ bantartica que a la de las provincias Guyano-Brasflicas, coincidiendo con el dominio Andino-Patag6nico como fuera esquematizado par Ringuelet.
