A new genus, Krameragallia, a segregate from the Neogeic genus Agalliopsis (Hemiptera: Cicadellidae: Megophthalminae)

摘要

A new genus, Krameragallia, type-species Agalliopsis rex gen. nov. Kramer, is described and illustrated. Krameragallia gen. nov. can be distinguished from all other known genera of Neotropical Agalliini by morphological features such as the following:largest size (7.4-9mm) among known species in the New World representatives of the subfamily; strong contrasting scarlet and black color pattern; aedeagus shaft very long, almost ribbon-like with ventral process; aedeagal apex bearing one pair of lateral slender processes on each side and first valvifer of female genitalia very well developed and hook-shaped. Female genitalia are described for the first time, including a highly unusual, well developed first valvifer. Notes on the genus as well as on the distinction between Krameragallia gen. nov., Agalliopsis Kirkaldy, Brasa Oman, and Chromagallia Linnavuori are given.
