Abstract
The notonectid fauna of the Baja California peninsula is composed of <br /><br />two genera, Notonecta represented by six species {hojfmani, kirbyi, shooterii, <br /><br />unifasciata, indica, melaena) and Buenoa by seven species (arizonis, omani, mar- <br /><br />garitacea, scimitra, albida, thomasi, platycnemis). With six exceptions, all col- <br /><br />lection sites (approx. 100) for the 13 species are recorded here for the first time. <br /><br />Distribution maps, discussion of the zoogeography of the notonectids on the Baja <br /><br />California peninsula, and hypotheses as to their origins and affinities are included. <br /><br />A key is provided to facilitate the identification of the 13 species.
