Scutellar sulcus wide medially divided by seven carinae ( Fig. 1D View FIGURE 1 ). Scutellum smooth, sparsely setose ( Fig. 1D View FIGURE 1 ). Mesopleuron smooth, sparsely setose ( Fig. 1E View FIGURE 1 ). Precoxal sulcus shallow, impressed not crenulated ( Fig. 1E View FIGURE 1 ). Metapleuron smooth, setose ( Fig. 1E View FIGURE 1 ). Medial area of metanotum with a very shot mid longitudinal carina anteriorly ( Fig. 1F View FIGURE 1 ). Propodeum smooth, sparsely setose.

Second metasomal suture sinuate, crenulate ( Fig. 2B View FIGURE 2 ). Metasomal tergite 3 2.60 × as wide as long. Metasomal tergites 3–5 longitudinally striate with distinct antero-lateral area ( Figs 2B, C View FIGURE 2 ). Hypopygium large, acute apically. Ovipositor sheath setose. Ovipositor with two distinct depressions and without distinct dorsal nodus and ventral serrations ( Fig. 2D View FIGURE 2 ).

Colour. Body yellow except antenna, mandible apically, eyes, ocellar region, pterostigma apically, all wing veins except basal 1/3 rd of C+SC+ R, propodeum, hind leg except tibial spurs, ovipositor sheath, ovipositor subapi- cally brown to dark brown, mesoscutum anteriorly and laterally, mesopleuron, mid leg reddish yellow.

Male. Unknown.

Distribution. India (Kerala).

Host. Unknown.

Etymology. APR dedicate this species to his friend, Mrs. Bindu, P.U., for being such a joyful and exceptional personality.

Comments. Undabracon binduae sp. nov. is close to U. cariniventris in having first flagellomere 1.50 × as long as wide. Apart from the differences listed in the key, U. binduae can be separated from U. cariniventris by the following characters; OOL 1.60 × as long as POL (vs 1.16 × in U. cariniventris ), metanotum with carina anteromedially (vs with carina postero-medially), hind wing vein C+Sc+ R with two hamuli (vs three in U. cariniventris ), hind femur, tibia 4.40 and 9.80 × as long as wide respectively (vs 5.10 and 7.30 × as long as wide respectively). First metasomal tergite longer than wide (vs as long as wide in U. binduae ) and third metasomal tergite without raised area antero-medially (vs with weak raised area antero-medially in U. cariniventris ).
