Many freshwater ecosystems receive allochthonous resource subsidies from adjacent terrestrial environments. In eastern North American forests, geographic broods of periodical cicadas emerge every 13 to 17 y to breed, and local abundances can sometimes be .300 individuals/m. Most individuals avoid predation, senesce after breeding, and become a resource pulse for forest ecosystems; some cicada c...

A new genus, Auritibicen gen. nov., is erected for the former members of Lyristes Horváth, 1926 (= Tibicen Latreille, 1825) from eastern Asia, designating Tibicen intermedia Mori, 1931 as the type species. Morphological comparisons are made among Auritibicen, Lyristes, and the American Tibicen species. Auritibicen pekinensis (Haupt, 1924) comb. nov. and Auritibicen slocumi (Chen, 1943) comb. no...
