The larva of Dythemis maya Calvert, 1906 and a redescription of the larva of D. sterilis Hagen, 1861 with a key to the larvae of the genus (Anisoptera: Libellulidae)

The last instar larva of D. maya is described and illustrated for the first time, based on reared material from Hidalgo, Morelos and Michoacan States, Mexico. The larva of D. maya is the largest of the genus and is remarkably different from other larvae, mainly by the reduced or wanting dorsal protuberances, and in the short lateral spines on the abdomen. A redescription of the larva of D. sterilis and some notes on other larvae of Dythemis are also provided, and all species are keyed.
