Abstract

Previously, the Berothidae of the Western Hemisphere all could be referred to three genera: Naizema Navas and Cyrenoberotha MacLeod and Adams, both restricted to South America, including one species each, and Lomamyia Banks, predominately North American. A generic level discussion of these taxa may be found in MacLeod and Adams, 1967, and in Aspöck, 1986. In material submitted to me for identification are representatives of two species, from Central and northern South America, which belong to a previously undescribed genus. Institutions wherein material has been deposited are abbreviated as follows: DHJ—Daniel H. Janzen Collection; FSCA—Florida State Collection of Arthropods; EGM—Ellis G. MacLeod Collection; IZAV—Instituto de Zoologia Agricola, Universidad Central de Venezuela, Maracay; MCZ— Museum of Comparative Zoology, Harvard University; NHMW— Naturhistorisches Museum, Wien, Austria; USNM—United States Nationsl Museum of Natural History, Washington.
