Abstract
Abstract. Larval taxonomy of caddisflies (Trichoptera) lags behind that of adults. Taxonomic knowledge of Nearctic representatives of Polycentropus Curtis, 1835 (Polycentropodidae) is particularly poorly resolved with the larva of only one of 30 species described and with no western Nearctic larvae known. Herein, the late-instar larvae of four of seven western Nearctic Polycentropus species are described and figured for the first time. A diagnostic matrix to assist in their identification is provided, new state records are reported, and previous records clarified. Issues regarding existing keys for larval Polycentropus sensu lato (i.e., Holocentropus McLachlan, 1878, Plectrocnemia Stephens, 1836, and Polycentropus) are discussed in light of new findings.
期刊介绍:
The Pan-Pacific Entomologist (ISSN 0031-0603) is published quarterly (January, April, July and October) by the Pacific Coast Entomological Society, in cooperation with the California Academy of Sciences. The journal serves as a refereed publication outlet and accepts manuscripts on all aspects of the biosystematics of insects and closely related arthropods, especially articles dealing with their taxonomy, biology, behavior, ecology, life history, biogeography and distribution. Membership in the Pacific Coast Entomological Society includes subscription to The Pan-Pacific Entomologist, and Society Proceedings typically appear in the October issue of each volume.
