Genus Tanna Distant, 1905

Tanna Distant, 1905 , Ann. Mag. Nat. Hist., (7), 15: 61. Type species: Pomponia japonensis Distant, 1892 ( Japan) . Neotanna Kato, 1927 : Trans. Nat. Hist. Soc. Formosa, 17: 26. Type species: Tanna viridis Kato, 1925 ( Formosa) .

Remarks. According to Chou et al., 1997, Neotanna is distinguishable from Tanna and Leptopsaltria in having the lateral surface of the male 3rd abdominal segment with a pair of tubercle-like projections. However, Neotanna was synonymized with Tanna by Hayashi (1978). And Lee and Hayashi (2004) showed that Tanna species have the lateral surface of the male 3rd and sometimes 4th abdominal sterna with a tuberclelike projection protruding laterally or posterolaterally. Therefore presence or absence of a pair of small protuberances on the male 4th abdominal sternum does not distinguish these taxa. We follow Hayashi (1978) in treating Neotanna as a junior synonym of Tanna . Therefore, Neotanna yunnanensis Lei et Chou, 1997 and Neotanna sinensis Ouchi, 1938 are here transfered to Tanna Distant, 1905 to become Tanna yunnanensis ( Lei et Chou, 1997) comb. nov. and Tanna sinensis ( Ouchi, 1938) comb. nov.
