Additional records of Odonata from El Salvador

El Salvador remains the most poorly known odonatologically of all the Central american countries, even though L.K, GLOYD (1981, Notul. odonatol. I: 133) more than doubled the list of species known to occur there. In my list of the Odonata of Middle America (D.R. PAULSON, 1982, in: S. H. Hurlbert & A. Villalobos-Figueroa, Eds, Aquatic biota of Mexico, Central America and the West Indies, pp. 249- -277, San Diego St. Univ.), 1 listed 41 species from the country, and 31 of these (76%) were from records from my own collection, as well as a summary of the literature. I should like to add details to these records and an additional two species to the list. These specimens represent the results of 7 collections made in the country by myself and Fred G. Thompson, as follows: (I) Dept. San Miguel, 8.4 mi. ESE San Miguel, 31 August 1964, FGT (I species; (2) Dept. San Salvador, Asino, I September 1964, FGT (6 species); (3) Dept. Santa Ana, Lago de Coatepeque, 2 September 1964, FGT (4 species); (4) Dept. La Libertad, pond 0.4 mi. W CA-12 on CA-2, 350', 25 June 1966, DRP (21 species); (5) Dept. La Libertad. waterfall 2.9 mi. SE jet. CA-I and CA-8, 2600', 25 June 1966, DRP(4 species); (6) same locality, 21 August 1967, DRP (4 species); (7) Dept. La Union, stream with pools 19.1 mi. N E San M iguel, 600’, 21 August 1967, DR P (11 species).
