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 : 559

Polyamia (Copolyamia) Sinada & Blocker

Diagnosis. Members of this subgenus may usually be recognized by the presence of supernumerary crossveins only in the clavus of the forewing, the relatively short, stout aedeagus, and the female seventh abdominal sternite, which has a broad posterior median lobe overlapping smaller paired lateral lobes.

Remarks. This subgenus is relatively well defined and homogeneous morphologically. Most of the included species are restricted to the temperate and subtropical warm season grasslands of the USA and Mexico. To facilitate comparison with subgenus Polyamia (Polyamia) DeLong and the new species of that subgenus described below, color illustrations are provided for two common North American species of Polyamia (Copolyamia) ( Figs 1–4 ).
