Key to Testudobracon species (*) from Vietnam

Based on females, the differences between Vietnamese species are keyed below:

1. In dorsal view, postero-lateral protuberance of sixth metasomal tergite hardly visible ( Figs 4h , 8g , 9c ); vein 3-SR of fore wing 0.8–1.1 × vein 2-SR; pterostigma rather long, 2.2–2.4 × as long as wide medially ( Figs 3 , 7 , 9e )....................... 2

- In dorsal view, postero-lateral protuberance of sixth metasomal tergite distinctly visible ( Figs 2g , 6c ); vein 3-SR of fore wing 1.4 × vein 2-SR; pterostigma broad 2.7 × as long as wide medially ( Figs 2h , 6i ).................................... 4

2. In lateral view, third–fifth metasomal tergites with distinctly rounded postero-lateral lobe like protuberances ( Fig. 9b ); metasomal tergites without blackish spots; antennae yellow. China, Vietnam...... Testudobracon flavus Wang, Chen & He

- In lateral view, third-fifth metasomal tergites with oblique postero-lateral lobe like protuberances ( Figs 4g , 8h ); metasomal tergites with blackish spots ( Figs 3 , 8c ); antennae brown...................................................... 3

3. Vein 3-SR of fore wing distinctly shorter (0.8 ×) than vein 2-SR ( Fig. 4k ); second metasomal tergite distinctly longer third tergite ( Fig. 4c ); ovipositor abruptly bent (curved) dowwards subapically ( Fig. 4i ), slightly longer than metasoma in lateral view ( Fig. 3 ), and apico-ventrally without serrations, but subapico-ventrally with serrations before ovipositor incision ( Fig. 4i ); mesopleuron largely black dorsally ( Fig. 4f ); mesosternum blackish brown............................................................................................................ Testudobracon descensus Long , sp. nov.

- Vein 3-SR of fore wing slightly longer (1.1 ×) than vein 2-SR ( Fig. 8k ); second metasomal tergite as long as third tergite ( Fig. 8c ); ovipositor straight ( Fig. 8i ), subequal to metasoma in lateral view, and apico-ventrally with serrations ( Fig. 7 ); mesopleuron and mesosternum reddish yellow ( Fig. 8f )......................... Testudobracon phiaoacus Long & PQMai, sp. nov.

4. Apex of lateral lobes third-fourth sharp ( Fig. 6g ); third metasomal tergite 2.8 × wider than long; apical median emagination (incision) of sixth metasomal tergite deep, touching basal sulcus of the tergite ( Fig. 6c ); ovipositor abruptly bent (curved) dowwards subapically, subapico-ventrally with serrations before ovipositor incision ( Fig. 5 ); prescutellar sulcus with 6 carinae ( Fig. 6d ).............................................................. Testudobracon imitator Long , sp. nov.

- Apex of lateral lobes third-fourth blunt ( Fig. 2c ); third metasomal tergite 2.5 × wider than long; apical median emagination (incision) of sixth metasomal tergite not touching basal sulcus of the tergite, 0.6 × as long as tergite medially ( Fig. 2g ); ovipositor straight, and apico-ventrally with serrations ( Fig. 1 ); prescutellar sulcus with 8–9 carinae ( Fig. 2a )..................................................................................... Testudobracon alius Long , sp. nov.
