Abstract
The cixiid planthopper Cixius franciscanus Stål, 1859 was described from
specimens asserted to be from San Francisco, California. Subsequent authorities have
interpreted the species in varied ways, culminating in the assertion that the species is
actually South American in origin. Here the species is redescribed and placed in a new
genus, Alviarus n. gen. as Alviarus franciscanus n. comb. based on available
specimens and the unpublished notes of the late Dr. Frank Mead. Further notes on the
American Pentastirini and the significance of preserving the illustrations and notes of
entomologists are discussed.
