Orfinger AB. 2023. Taxonomic Revision of the Polycentropus confusus Species Group (Trichoptera: Polycentropodidae). Journal of Natural History. 57(41-44):1825–1916
ABSTRACT: The Polycentropus confusus Species Group (Trichoptera: Polycentropodidae) comprises 19 nominal species occurring throughout the eastern Nearctic Region. This group has never been comprehensively treated, prompting its full revision here. Males of all 19 species are redescribed and illustrated, and the 14 known females of the group are described and illustrated, including the original descriptions and illustrations for the females of P. alabamensis Hamilton, Harris, and Lago, 1990, P. carolinensis Banks, 1905, and P. chelatus Ross and Yamamoto, 1965. Neotypes are designated for P. alabamensis and P. elarus Ross, 1944, and dichotomous keys to males and females are provided. New state and province records are reported, one new country record is reported, erroneous records are corrected, biological notes are provided, and the known distribution of each species is summarised.
