Abstract
The six species of Lissorhoptrus LeConte known previously from Noth America north of Mexico are treated taxonomically. Two subspecies are raised in rank to species, Lissorhoptrus insularis Kuschel and Lissorhoptrus longitarsis Kuschel, new rank, and one species, Lissorhoptrus robbinsorum O'Brien, new species, is described. The nine species include one that attacks rice, Oryza sativa L., and two that attack wild rice, Zizania aquatica L. The new species L. robbinsorum has been reared from the aquatic grasses Echinochloa crus-galli (L.) and Echinochloa holciformis (H. B. K.) Chase. The genus and previously described eight species are redescribed, and the nine species are keyed. Photographs of the habitus and the male hind tibial mucro of all species and the male genitalia of selected species are provided.
