Abstract

Adults and larvae of a new species of Contulma Flint (Trichoptera:Anomalopsychidae) are described from Ecuador. The new species is similar to Contulma papallacta Holzenthal and Flint, but differs in having shorter, less spatulate dorsolateral processes and shorter setose lateral processes of segment IX in the male genitalia. Monthly Hess, sticky trap, and emergence-trap collections indicated that the new species is uncommon, probably univoltine, but with continuous larval growth and extended adult emergence, and has algivorous larvae.
