Vol. 88, Nos. 9 & 10, November & December, 1977 249 THE GENVS AC/NOFTER US (HOMOPTERA: CICADELLIDAE) IN MEXICO AND THE NEOTROPICAL REGION' 2 3 Rauno E. Linnavuori, Dwight M. DeLong ABSTRACT: New records of the genus Acinoptenis Van Duzee are listed from Mexico and Central America. Two species, A. perdicoenis n. sp. and A. ignalanum n. sp. are described as new, and a new name is proposed for A. reticulatus Beam, and Lawson. DESCRIPTORS: ^QoXiop'\ca\, Acinopterus, species (Homoptera: Cicadellidae) The main range of the genus Acinoptenis V.D. hes in North America where 25 species are known, most of them occurring in the arid and semiarid southwestern parts of the U.S. The Nearctic species were revised by Beamer and Lawson (1938), Beamer (1944) and Knull (1944). Three species of the genus are recorded from the Neotropical Region (Linnavuori 1959:58-60). Two of these are North American (A. acuminatus V.D., known only from Cuba, A. angitlatus Laws, widespread) and only one, A. gentilis (Berg) is purely Neotropical. The following article is based on a large number of specimens of the genus from Mexico, Central and South America in the DeLong collection at Ohio State University. Two new species are being described from Mexico and A. inornatus (Bak.) is recorded for the first time from that country. Acinoptenis angulatus Laws.
