本文首次描述了大鲵Siphlonurus davidi（Navás，1932）的成虫和成虫。成虫有色彩鲜艳的翅膀和交叉静脉，MP在其基部分叉不对称，肘区较长，有更多的闰，与同类相比，它有相对简单的阴茎和较大的后翅。脉序和生殖器表明它是该属中的一个近效种。最后，提出了亚洲彩翅Siphlonurus种的检索表。
The imagos and nymphs of Siphlonurus davidi (Navás, 1932) are described for the first time. The adult has colourful wings and cross veins, the MP is forked asymmetrically at its base, a long cubital area is present with more intercalaries, and it has a relatively simpler penis and larger hindwings compared to its congeners. The venation and genitalia show that it is a plesiomorphic species in the genus. A key to the Asian species of Siphlonurus with coloured wings is provided in conclusion.
