Gaeana (from Sanskrit: गायन, romanizedgāyana, lit.'singer'[1]) is a genus of cicadas, most members of which have colourful marking on their forewings, found across tropical and temperate Asia. Their bright wing patterns have been hypothesized as being a case of Batesian mimicry where the toxic models may be day-flying moths of the subfamilies Zygaeninae and Arctiinae.[2][3] It was thought to be related to the genus Tosena but is differentiated by the exposed tympanum and lacks spines on the sides of the pronotum[4] and now in a separate tribe.

Some species like G. maculata have been found to show a great deal of patterning variability across geography.[5]

Species

Species included in the genus have varied over time. A molecular phylogeny study in 2025 retains only three species within the genus:[5]

  1. Gaeana atkinsoni Distant, 1892
  2. Gaeana maculata (Drury, 1773) - type species - with several former species synonymized - G. consors, G. hainanensis, G. cheni and G. nigra
  3. Gaeana chinensis Kato, 1940
