The sister species Ischnura elegans and I. graellsii (Odonata: Coenagrionidae) are. sympatric species of Bignoniaceae occur in one neotropical forest community.

Mechanical isolating factors (flower size and shape in relation to pollinators) separate entire genera of neotrop-. Understanding the distribution patterns of closely related species is critical because the extent to which their ranges overlap determines the opportunity for competition and hybridization.
