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.
