Genus Stereocephalus Lynch , 1 8 8 4

TYPE SPECIES. Stereocephalus seriatipennis Lynch, 1 8 8 4

DIAGNOSTIC FEATURES. The unique and single most diagnostic feature of Stereocephalus is the broad, compressed, and glabrous fourth segment of the maxillary palpus (Herman, 1 9 7 9: figs. 2 2, 2 3). Other distinguishing characters include the deeply emarginate, edentate labrum (Herman, 1 9 7 9: fig. 6), and the bent first antennomere (Herman, 1 9 7 9: fig. 7).

DISTRIBUTION AND BIOLOGY. The genus is found in Argentina, Paraguay, Brazil, Peru, Ecuador, Venezuela and Costa Rica.

REMARKS. Few specimens are known for the genus and specimens have been found in few localities. Nearly all of the reported localities each yielded only one specimen. The most commonly collected species, S. seriatipennis , is widespread. It is probable that more species of this genus will be found.
