This order once encompassed all insects with a complex network of
wing veins, regardless of whether their metamorphosis was
incomplete or complete. By the early 20th century, most of the
species had been transferred to new orders, leaving only a small
percentage of the insects once assigned to the Neuroptera remaining
in that order. By the second half of the 20th century, some of the
taxonomists began to believe that the fragmentation of this order
had gone too far, and that the order Megaloptera needed to be
grouped in some way with Neuroptera, either by making them
suborders of the same order or by creating a superorder to
accommodate both. This volume provides a discussion of both taxa,
tentatively regrouping both in the order Neuroptera. While all
known species of Megaloptera in South America have completely
aquatic larval stages, few species in the suborder Planipennia,
formerly called Neuroptera sensu stricto, are aquatic during any of
their life stages. The most interesting of the exceptions are
species in the family Sisyridae, some of which develop as larvae
inside freshwater sponges.Because only a relatively small number of
species are still included in Neuroptera sensu lato, this book
provides keys to all known South American species that have been
described well enough to be identified with any degree of
certainty. Many species in the family Chloropidae, the neuropteran
family with the greatest number of recognized species in South
America, have proven to be valuable as biological controls for
insect pests in agriculture. Their importance for tropical
agriculture is another reason for including terrestrial species in
this book. The series will continue with volumes providing keys to
identify species of other South American orders, but in most cases,
only aquatic insects can be included in the keys to the species.
