    Five new species of Polycentropodidae (Trichoptera) from Ecuador and Venezuela
    (Magnolia Press, 2005) Hamilton, Steven W.; Holzenthal, Ralph W.
    Diagnoses, descriptions and illustrations of male genitalia are given for four new species of the Polycentropus gertschi group, Polycentropus cressae n. sp., Polycentropus neblinensis n. sp., Polycentropus quadricuspidis n. sp., and Polycentropus silex n. sp. The former two are from Venezuela and the latter two from Ecuador. In addition, a diagnosis, description and set of male genitalia illustrations are provided for Polyplectropus beccus, a new species from Ecuador. The generic placement of this species, while currently appropriate, may require reclassification pending completion of ongoing studies on Neotropical polycentropodids.

    A new species of Smicridea McLachlan (Trichoptera:Hydropsychidae) from Venezuela and its role in travertine biogenesis
    (The North American Benthological Society, 2003) Paprocki, Henrique; Holzenthal, Ralph W.
    We collected an undescribed hydropsychid caddisfly, Smicridea (Smicridea) travertinera, n. sp., from 2 sites in Venezuela. One of the sites, Quebrada El Charo, flowed over extensive calcareous formations of travertine, which were covered with retreats and capture nets of the new species. Smicridea travertinera was the most abundant aquatic insect colonizing travertine.We describe the adult male, the retreat and net, and gut contents. The retreat consisted of an aperture in the travertine with a capture net. Retreat-making behavior appears to cause both the biogenesis and erosion of the travertine formations.
