A review of the leafhopper genus Jikradia with descriptions of four new species (Homoptera: Cicadellidae)

The genus Jikradia Nielson extends from eastern North America to Central America and the Galapagos Islands. Four additional new species are described and illustrated: J. mexicana (Mexico) J. longa (Costa Rica, Guatemala, Mexico), J. zurquiensis (Costa Rica) and J. lizanoi (Costa Rica). J. mexicana general color is ochraceous; the aedeagus without seta-like spine. Jikradia longa, general color is light ochraceous; the aedeagus with long seta-like process subapically with three spine-like setae opposite to single subapical seta. Jikradia zurquiensis, general color brown; aedeagus with single seta-like process subapically with three small spine-like setae basad of single subapical setae on the opposite lateral margin of aedeagus. Jikradia lizanoi, general color brown; aedeagus asymmetrical, long, narrow, tube-like, in lateral aspect with sharply pointed apex, with two long seta-like processes subapically with four spine-like setae. A revised key to all known species, and subspecies, based on male genitalia, is also presented. Se describen e ilustran cuatro especies nuevas de Jikradia Nielson: J. mexicana (México) J. longa (Costa Rica, Guatemala, México), J. zurquiensis (Costa Rica) y J. lizanoi (Costa Rica). El trabajo inlcuye una clave ilustrada para todas las subespecies, con base en los aparatos genitales masculinos.
