VON ELLENRIEDER, Natalia. Revalidation of Argentagrion and redefinition of Homeoura, with the description of H. obrieni n. sp. (Odonata: Coenagrionidae). Rev. Soc. Entomol. Argent. [online]. 2008, vol.67, n.1-2, pp.81-106. ISSN 0373-5680.

Argentagrion Fraser, currently considered a synonym of Homeoura Kennedy, is revalidated; both genera are rediagnosed and their species illustrated, keyed and mapped. Ischnura sobrina Schmidt is transferred to Homeoura, and a new species, H. obrieni is described, resulting in five species being included in Homeoura (H. chelifera (Selys), H. lindneri (Ris), H. nepos (Selys), H. obrieni sp. nov. and H. sobrina (Schmidt) comb. nov.) and two in Argentagrion (A. ambiguum (Ris) and A. silviae Bulla).

Palavras-chave : Odonata; Coenagrionidae; Argentagrion; Homeoura; South America.
