Revalidation of Argentagrion Fraser and redefinition of Homeoura Kennedy, with the description of H. obrieni n. sp. (Odonata: Coenagrionidae)

Abstract

Se revalida Argentagrion Fraser, considerado actualmente como un sinónimo de Homeoura Kennedy; ambos géneros son rediagnosticados y se proporcionan ilustraciones, claves y mapas para sus especies. Se considera que Ischnura sobrina Schmidt pertenece a Homeoura y una nueva especie, H. obrieni, es descripta, resultando un total de cinco especies incluidas en Homeoura (H. chelifera (Selys), H. lindneri (Ris), H. nepos (Selys), H. obrieni sp. nov. y H. sobrina (Schmidt) comb. nov.) y dos en Argentagrion (A. ambiguum (Ris) y A. silviae Bulla).

ABSTRACT. 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).
