. Nymphal characters which distinguish the nine species of the Enchenopa binotata complex (key included) are delineated for future formal species descriptions. A phylogenetic tree using these characters is presented and compared to a tree derived from allozyme data. Three pairs of sister species are defined, two of these pairs meeting strict phylogenetic and biological criteria which suggest sympatric speciation through host shifts.
