Resumen:
This paper provides observations on mating behavior, oviposition, pupation, and adult life span of Platyneuromus from northeastern Mexico, as well as on larval habitats of Chloronia, Corydalus, and Platyneuromus recorded in Mexico and Costa Rica. Platyneuromus' mating behavior differed from that of Corydalus in that males only displayed threatening positions but did not fight. Further, they did not rest their mandibles over female's body after mating but softly bit and touched female's wings and abdomen with their mandibles. Platyneuromus larvae in northeastern Mexico appear to prefer higher elevation streams and a narrower spectrum of ecological conditions than Corydalus. Currently stable New World dobsonfly taxonomy should facilitate research on the largely unstudied life history traits of Neotropical taxa.
