Description of the final instar larvae of Erythrodiplax atroterminata Ris and E. corallina (Brauer) (Odonata: Libellulidae)

Abstract

The final stage larva of Erythrodiplax atroterminata and E. corallina are described and illustrated based on reared specimens from Argentina. A comparative analysis of all known larvae of Erythrodiplax from Argentina is provided.

Description of final stadium larva ofErythrodiplax connataandE. basifuscaand redescription of that ofE. minuscula(Odonata: Libellulidae)

“…The final stadium larvae of the genus Erythrodiplax show a great uniformity of metric and morphological characters, making the distinction of species very difficult (Needham et al, 2000; von 70% of its species are described or keyed (e.g. E. atroterminata, E. basifusca, E. bromelicola, E. connata, E. fusca, E. justiniana, E. melanorubra, E. minuscula and E. paraguayensis) (Carvalho et al, 1991;Costa et al, 2001;Garré et al, 2008;Muzón & Garré, 2005;Needham, 1904;Needham et al, 2000).…”
