(A.) dentata sp. nov. (Taiwan), S. (A.) distincta sp. nov. (Vietnam), S. (A.) exilipes sp. nov. (Java, Indonesia), S. (A.) farinosa sp. nov. (Sabah, Malaysia), S. (A.) fimbriata sp. nov. (Thailand), S. (A.) furcillata sp. nov. (Vietnam), S. (A.) ghatsi sp. nov. (India), S. (A.) gigantea sp. nov. (China), S. (A.) granditarsis sp. nov. (China), S. (A) hamulata sp. nov. (India), S.

(A.) licina sp. nov. (Thailand), S. (A) lobulata sp. nov. (Vietnam), S. (A.) lucida sp. nov. (Vietnam), S. (A) nigrotarsata sp. nov. (Vietnam), S. (A.) nubicola sp. nov. (Thailand), S. (A.) ornata sp. nov. (China), S. (A.) perlobata sp. nov. (Taiwan), S. (A.) plautus sp. nov. (China), S. (A.) prolixa sp. nov. (Malaysia, Thailand), S. (A.) setosa sp. nov. (Nepal, India), S (A.) spathigera sp. nov. (Philippines), S (A) spenceri sp. nov. (Vietnam), S (A.) strigillata sp. nov. (Vietnam), S. (A) taiwanensis sp. nov. (Taiwan), S. (A.) umbrosa sp. nov.

The males of S (A.) apicalis Shiraki, 1930, S (A.) tricoloripes Brunetti, 1915 and S. (A.) varidissima Shiraki, 1930 and the females of S (A.) achaeta Hippa, van Steenis & Mutin, 2015, S. (A.) index Hippa, van Steenis & Mutin, 2015, S. (A.) mirifica Hippa, van Steenis & Mutin, 2015 and S. (S.) quadriseta Huo & Ren, 2006 are described for the first time. Sphegina (5) quadriseta is recorded for the first time in the Oriental region. A key to all the Oriental species of Sphegina is provided. The Oriental fauna of Sphegina now comprises 94 species.
