Collections of both species included speci- mens taken north ofPatagonia. A. elsia was describedby CALVERT (1952) from specimens from Pacasmayo, Peru. He also included material from Lima, Pachitea, vicinity of Chosica, vicinity of Villa and Repartition (Peru), Tacna, Azapa, Mini-Mini and Curico (Chile), and “Patagonia”. As the description and later redescription of A. elsia (CALVERT, 1952, 1956) do not easily allow its separation from the other species of the subgenus Neureclipa Navas, 1911 (sensu CALVERT, 1952), a redescription is included, together with the description of a new species of the subgenus Hesperaeschna Cockerell, 1913. For the wing venation the terminology given by RIEK & KUKALOVA-PECK (1984), and for the description of the abdominal colour pattern that proposed by WALKER (1912). Material examined is deposited at the following collections: MLP - DepartamentoCientlfico Entomologla, Museo de La Plata, Buenos Aires, Argentina; FML — Fundacion Miguel Lillo, Tucuman, Argentina; - MNFIN Museo Nacional de Historia Natural de Santiago, Chile; IEUM - Institute de Entomologia, Universidad Metropolitana de Ciencias de la Educacion, Santiago, Chile; — UMMZ University of Michigan,Museum of Zoology, MI, U.S.A.
