Testudobracon phiaoacus Long , sp. nov. , holotype, female (lateral) Colour . Body yellow to reddish yellow ( Fig. 7 ); antenna brown; head and mesonotum reddish yellow, except malar space, mandible, labrum, palpi and lateral side of pronotum yellow; propodeum and metapleuron brown; fore and middle legs yellow, except telotarsi brown; hind leg yellow, except hind coxa and femur medially, tibia apically and hind tarsus brown; wing veins brown but paler basally; first-third metasomal tergites yellow, except third tergite medially and laterally dark brown; fourth–sixth metasomal tergites pale yellow, posterio-lateral protuberances dark brown ( Fig. 8h ); ovipositor sheath brown; ovipositor yellow. Male. Unknown. Distribution . NE Vietnam ( Cao Bang : Phia Oac NP). Biology . Unknown. Etymology . The new species is named after the locality (Phia Oac NP), where the holotype was collected. Notes . The differences between T . descensus sp. nov. and T . phiaoacus sp. nov. were given in the key; this new species is close to T. guangxinensis Wang, Chen & He , from China , but differs from the latter by the following characters: 1) Propodeum smooth, with a complete median longitudinal carina; 2) Middle lobe of mesoscutum with sparse but discretely punctate, anterio-medially with a weak longitudinal ridge, lateral lobes of mesoscutum with discrete punctures (nearly smooth in T. guangxinensis ); and 3) Third–fifth metasomal tergites with oblique posterolateral lobe like protuberances in lateral view (rounded postero-lateral lobe like protuberances in T. guangxinensis )
