Head. Antenna incomplete with 42 segments. Length of first flagellomere 1.20 × second. First and second flagellomere 1.50, 1.20 × as long as wide respectively. Head 1.20, 1.00 × as wide as long in anterior and dorsal view respectively. Face 1.00 × as wide as long, rugose, setose, raised medially with a short mid longitudinal carina anteriorly ( Fig. 1B View FIGURE 1 ). Height of clypeus: inter tentorial distance: tentorio ocular distance= 1.5: 2.6: 1.0. Clypeus separated from face with a shallow crenulated transverse groove with a protruding ventral carina ( Fig. 1B View FIGURE 1 ). Tentorial pit deep ( Fig. 1B View FIGURE 1 ). Malar suture absent. Malar space 0.90 × basal width of mandible. Length of eye 4.20 × as long as temple in dorsal view, sparsely setose, slightly emarginated beyond antennal sockets ( Fig. 1C View FIGURE 1 ). Frons distinctly impressed, smooth, setose anteriorly with a complete, deep mid longitudinal groove ( Fig. 1C View FIGURE 1 ). POL: diameter of ocellus: OOL= 1.0: 1.8: 1.6. Vertex smooth, glabrous ( Fig. 1C View FIGURE 1 ). Occiput smooth, sparsely setose ( Fig. 1C View FIGURE 1 ).

Mesosoma . Mesosoma 2.00 × as long as high. Pronotum smooth laterally, sparsely setose anteriorly and posteriorly ( Fig. 1E View FIGURE 1 ). Mesoscutum smooth, sparsely setose along notaular line ( Fig. 1D View FIGURE 1 ). Notauli indistinct ( Fig. 1D View FIGURE 1 ). 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.

Wings. Fore wing: Angle between vein C+SC+ R and 1RS 82°. Vein (RS+M)a curved. Ratio of length of veins r: 3SRa: 3SRb= 1.0: 3.4: 4.3 and 2RS: 3SRa: rs-m= 1.5: 3.3: 1.0. Second submarginal cell parallel sided ( Fig. 2E View FIGURE 2 ). Vein 1cu-a antefurcal ( Fig. 2E View FIGURE 2 ). First subdiscal cell with a brown patch medio-posteriorly. Vein 2cu-a widened basally narrowing apically. Hind wing: Apex of vein C+Sc+ R with two hamuli. Vein R longitudinal. Vein cu-a straight. Vein 1r-m 2.90 × R.

Legs. Ratio of lengths of fore femur: tibia: tarsus= 1.0: 1.0: 1.5. Hind femur, tibia and basitarsus 4.40, 9.80 and 7.10 × as long as wide respectively. Hind coxa smooth, setose ( Fig. 1E View FIGURE 1 ). Tarsal claw without pointed basal lobe ( Fig. 2D View FIGURE 2 ).

Metasoma. First metasomal tergite 1.40 × as long as wide apically, longitudinally striate with a large raised median area margined laterally by crenulated groove, with a short, deep mid longitudinal groove basally, smooth laterally and antero-laterally ( Fig. 2A View FIGURE 2 ). Second metasomal tergite 1.20 × as long as third tergite, longitudinally stri- ate with a large triangular midbasal, longitudinally striate area bordered by crenulate grooves and lateral shallow, crenulated grooves, midbasal area 0.80 × as long as tergite connected with second metasomal suture by a short longitudinal carina, lateral sides of midbasal area inflated, smooth ( Fig. 2B View FIGURE 2 ). 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 ).
