Siobla formosana Takeuchi, 1927

( Figs 1 e, 1f, 4e, 4f, 8a–c, 9k, 9x, 10g, 10h)

Siobla formosana Takeuchi, 1927: 208 . ♀, type locality: Musha, Taiwan ( China). Siobla formosana: Niu & Wei, 2011: 162 . redescription.

Distribution. China ( Taiwan).

Remarks. This species was redescribed in detail in Niu & Wei (2011). Siobla formosana is very close to Siobla fumipennis Malaise, 1945 but differs from it in the basal part of wings in both sexes hyaline; the pterostigma dark brown; the second abdominal tergite entirely yellow brown and metabasitarsus pale brown in female; the abdominal tergite 4 in male largely yellow brown; and the trochanters usually yellow brown. S. formosana is also similar to S. jiangi and S. zuoae . See the key above for the differences between them.
