Oligoclada Karsch, 1890

The main reference for this genus is Borror (1931); see also Geijskes (1948) and Rehn (2003). Oligoclada ranges over most of South America north of Paraguay, with nine species in Ecuador. They are small, dark dragonflies ( Fig. 105 ) that inhabit small streams, backwaters of streams and adjacent swamps, canals, ponds and man-made reser- voirs. Only two of the 23 species have been reared.
