Neocordulia longipollex Calv., a remarkable new record from Mexico (Anisoptera: Corduliidae)
Notulae odonatologicae , Volume 2 - Issue 6 p. 100- 101
Members of the family Corduliidae are known to be poorly represented in Mexico and Central America (P.P. CALVERT, 1909, Em. News 20: 40*MI2; 1942, Proc. VllUh Am. Sci. Congr.. pp. 323-331; J.G. NEEDHAM, 1933, Em. News 44: 88-90) and also South America (D.C. GHIJSKES, 1970. Stud. Fauna Suriname 12: 1-42). Up to now only two members of this family have been recorded from Mexico: Gomphomacromia mexicana Needham and Macromia annulata Hag. Gomphomacromia mexicana was the first corduliid recorded from Mexico (NEEDHAM, 1933, l.c.). This species has its nearest relatives in the temperate zone of southern South 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.). Macromia annulata has been recorded from the state of Nuevo Le6n under the synonym of M. caderita Needham (J.G. NEEDHAM & M.J. WESTFALL, 1954, A manual of the dragonflies of North America. Univ. California Press, Berkeley). Members of this genus are widely distributed in North America, so the presence of this species in northern Mexico is not surprising. Recently I received a small collection of Odonata from the highlands of Oaxaca State (southern Mexico) through the kindness of Mr. Adolfo Ibarra, (Institute de Biologia, UNAM). To my surprise, there was included a single specimen belonging to the family Corduliidae, which 1 further examined and determined as Neocordulia longipollex Calvert. The genus Neocordulia had not been previously recorded for Mexico, and is constituted by five known species, viz., N. androgynis (Sel.), N. batesi (Sel.), N. longipollex Calvert, N. setifera (Sel.) and N. volxemi (Sel.) (R. MARTIN, 1914, Genera Insect. 155: 1-32). All species have a South American distribution except N. longipollex, which was described from a single male from Costa Rica (San Jacinto, W ofGuapiles) (CALVERT, 1909, l.c.). More recently, N. longipollex has also been recorded for Panama and South America (PAULSON, 1982, Lc.)
