Polyamia (Polyamia) DeLong

Duan, Yani & Dietrich, Christopher H., 2018, A new species of Polyamia DeLong (Hemiptera: Cicadellidae: Deltocephalinae: Deltocephalini) representing the first record of the genus from South America, Zootaxa 4457 (4), pp. 557-567 : 562

Polyamia (Polyamia) DeLong

Diagnosis. Members of this subgenus may usually be recognized by the presence of supernumerary crossveins in both the clavus and corium of the forewing, the relatively long, slender aedeagus, and the medial posterior lobe of female abdominal sternite VII either absent or no wider than the lateral lobes.

Remarks. This subgenus is less well defined and more morphologically heterogeneous than Polyamia (Copolyamia) Sinada & Blocker. Most species occur in subtropical and tropical grasslands of Mexico and Central America, although the type species, P. (P.) weedi Van Duzee , illustrated below ( Figs 7–8 ), is widespread in the eastern USA. Here we describe the first species of the subgenus (and genus) recorded from South America.
