Diagnosis. Females of Zaglyptogastra species are readily distinguished from all other braconine genera by the combination of the following characters: scapus longer ventrally than dorsally ( Fig. 4 ); eyes glabrous, emarginate; clypeus with a transverse median carina ( Fig. 3 ); the first subdiscal cell of fore wing without oval with thickened veins ( Fig. 11 ); tarsal claws simple without a large basal lobe; dorsal carina of the first metasomal tergite present; the second metasomal tergite lacking a distinct mediobasal area; the third-fifth metasomal tergites not serrate apically; distal part of ovipositor strongly depressed and formed into four arch-like sections ( Fig. 9 ) [occasionally three in some Afrotropical species El-Heneidy & Quicke (1991)].

The new species can be keyed via the fifth couplet in the key provided by El-Heneidy & Quicke (1991) as follows:

5b Ovipositor apex laterally compressed, ovipositor sheath setae short; base of hind wing with a rather large glabrous area [see Fig. 13 in El-Heneidy & Quicke (1991)]; head yellow or rufouse, except stemmaticum black; fore wing veins 1-SR, 1-M and 1-SR+M yellow [see Fig. 4 in El-Heneidy & Quicke (1991)] .................................................... ....................................................................................................................... Z. aswada El-Heneidy & Quicke, 1991 ,

bb. Ovipositor apex laterally compressed, ovipositor sheath setae long ( Fig. 12 ); base of hind wing sparsely setose lacking a rather large glabrous area ( Fig. 10 ); head yellow, except frons medially, stemmaticum and vertex largely black ( Fig. 2 ); fore wing veins 1-SR, 1-M and 1-SR+M blackish ( Fig. 11 ) .............................................. Z. vietnamica sp. n.
