An illustrated key to the genera and subgenera of the Alysiini (Hymenoptera, Braconidae, Alysiinae) from China is presented. Three genera new for China are reported: Adelurola Strand, 1924, Anisocyrta Foerster, 1863, and Pentapleura Foerster, 1863. The total for China is 26 genera of Alysiini and an additional seven subgenera (excluding the nominal subgenera, which are included in the total of genera). The known Chinese species are listed under each genus and the biology is summarised. Separatatus sinicus (Zheng, Chen & Yang, 2012) and Grammospila eurys (Chen & Wu, 1994) are new combinations. Regetus Papp, 1999, and Adelphenaldis Fischer, 2003, are new synonyms of Eusynaldis Zaykov & Fischer, 1982. In addition, Eusynaldis Zaykov & Fischer and Synaldis Foerster, 1863, are treated as subgenera of Aspilota Foerster, 1863, and Dinotrema Foerster, 1863, respectively. An aberrant species of Separatatus Chen & Wu, 1994, S. parallelus sp. n., is described from Yunnan and Hainan.

In this paper three genera are listed as new for China: Adelurola Strand, Anisocyrta Foerster and Pentapleura Foerster. The total for China is 26 genera of Alysiini and seven subgenera (without the nominal subgenera; they are included in the total of genera), comprising 132 species.

The genera Regetus Papp and Adelphenaldis Fischer share with Eusynaldis Zaykov & Fischer the derived character of the reduced vein 1-SR+M of the fore wing. The only difference between Eusynaldis and both other taxa is the shortened vein r-m of fore wing, a feature often variable within species of Aspilota Foerster and not suitable for separation of genera; the same applies to the enlarged propodeal spiracle of Regetus Papp. Eusynaldis Zaykov & Fischer is recognised as subgenus for convenience, because the recognition as genus likely renders the genus Aspilota Foerster paraphyletic, and the loss of vein 1-SR+M occurred probably more than once in the genus.

A diverse genus including several spp. without oblique subocular depression for which the names Prosapha Foerster, 1863, Panerema Foerster, 1863, and Pterusa Fischer, 1958, are available. An extensive worldwide phylogenetic study of the genus Dinotrema is necessary before a well-based decision can be made on a possible recognition as subgenus or genus. Synaldis Foerster is recognised as subgenus for convenience, because the recognition as genus likely renders the genus Dinotrema Foerster paraphyletic, and the loss of vein 1-SR+M occurred probably more than once in the genus.
