Abstract
A total of 31 species of Argia are reported as present in Ecuador, of which two, A. huanacina Förster and A. jocosa Hagen, constitute first records for the country, and five are new to science and are described here: Argia acridens n. sp. (Holotype ♂: ECUADOR, Manabí Prov., 79 km west of Santo Domingo de los Colorados, 260 m, 7 May 1975, Paul J. Spangler et al. leg., in USNM), Argia cuspidata n. sp. (Holotype ♂: ECUADOR, Santo Domingo de los Tsáchilas Prov.: 19 km east of Santo Domingo de los Colorados, 740 m, 7 May 1975, A. Langley & J. Cohen leg., in USNM), Argia philipi n. sp. (Holotype ♂: BOLIVIA, Cochabamba Dept., Chapare Prov.: stream 5 km south of Villa Tunari, noon, 350 m, 4 November 2001, Jerrell J. Daigle leg., in FSCA), Argia selysi n. sp. (Holotype ♂: ECUADOR, Napo Prov.: Jatun Yacu, Napo River watershed, 700 m, 18 April 1935, William Clarke-Macintyre leg., in UMMZ) and Argia tennesseni n. sp. (Holotype ♂: ECUADOR, Orellana Prov.: stream 8.5 km east of Loreto, 360 m, 14 September 1997, Kenneth J. Tennessen leg., in FSCA). The new species are illustrated and diagnosed from their congeners and their known distribution areas are mapped. To aid in identification, illustrations needed for diagnosis and / or distribution maps of closely related species are also provided, including: A. adamsi Calvert, A. difficilis Selys, A. dives Förster, A. huanacina Förster, A. fulgida Navás, A. infrequentula Fraser, A. jocosa Hagen in Selys, A. joergenseni Ris, A. limitata Navás, A. medullaris Selys, A. orichalcea Hagen in Selys and A. ulmeca Calvert. Argia columbiana Navás and A. rectangula Navás are treated as subjective junior synonyms of Argia medullaris Selys. A key to the eight known metallic red Argia species from South America is provided.

| Male of Argia tennesseni at a small forest stream about 12 km NE of Loreto in Ecuador, Orellana Province, photographed by Kenneth J. Tennessen on 26 October 2013. 'This forest was being cut down, and the little streams that back then held up to 10 species of Argia, may no longer be a suitable habitat for some of these species that require forest shade and bank protection'
