Description of a second species of <i>Angucephala</i> DeLong &amp; Freytag (Hemiptera: Cicadellidae: Iassinae: Gyponini)

A second species of Angucephala DeLong & Freytag, 1975 is described and illustrated from Ecuador, A. freytagi sp. nov. (Napo Province). This species can be distinguished from the type species (A. mellana DeLong & Freytag, 1975) mainly by features of the male pygofer and styles. A redescription of the genus and illustrations of the type species are also provided.
