Progomphus Selys, 1854

The largest genus of Gomphidae with 68 described species, at least seven of which are found in Ecuador. The genus is found only in the New World. Basic references are by Belle (1973, 1991b); new species are likely to be found. Nymphs of these small to medium-sized gomphids bury themselves in sand and silt of mainly small streams to large rivers. The image ( Fig. 78 ) from Eastern Ecuador is of uncertain specific identification.
