sp. nov.
, Female. 7. Fore wing; 8. Hind wing; 9. Head, dorsal aspect; 10. Mesosoma; 11. Head, frontal aspect; 12. Metasomal tergites 1st3rd; 13. Hind leg; 14. Antenna; 15. Tarsal claws with basal lobes; 16. Ovipositor and ovipositor sheaths. Scale: 1.0 mm.
Head
. Antenna 49 segmented; length of third antennal segment 1.8 times fourth segment; third, fourth and penultimate segments 4.5, 2.5 and 2.0 times their widths respectively; apical segment 2.5 times their width (
Fig.14
); length of maxillary palpi 0.9 times height of head; vertex and frons granulate; length of eye 2.3 times of temple in dorsal view (
Fig. 9
); temple roundly narrowed posteriorly; AOL: POL: OD: OOL = 3: 3: 3: 9; clypeus almost flat (
Fig. 11
) and ventral margin protruding; face smooth medioventrally and some what finely transversally rugulose behind antannal sockets; length of malar space 1.3 times basal width of mandible.
Mesosoma
. Length of mesosoma 1.8 times its height; episternal scrobe linear and deep; mesoscutum smooth, only medioposteriorly granulate with a short carina, medioanteriorly with a short groove; scutellar sulcus wide with a longitudinal carinae (
Fig. 10
); scutellum with distinct pit anteromedially; metapleuron finely puntulate with long whitish setae; propodeum without median carina with coarsely granulate.
Wings
. Fore wing (
Fig. 7
) vein r: 3SR: SR1 = 5: 7: 35; cua interstitial; 2SR: 3SR: rm = 11: 7: 8; hind wing (
Fig. 8
) vein 1rm straight, free from 1SC+R and about 2.0 times longer than vein 2SC + R; 1SC + R about as wide as 1rm.
Legs
.
Hind
coxae granulate; length of femur, tibia and basitarsus of hind leg 3.33, 10.0 and 3.75 times their widths respectively; length of spurs of hind tibia 0.4 times of hind basitarsus (
Fig. 13
).
Metasoma
. Length of first tergite 0.86 times its apical width, its surface behind united dorsal carina coarsely reticulate, its lateral areas wide and partially smooth; grooves of second tergite narrow, coarsely crenulate, not meeting each other and not reaching second metasomal suture, resulting without a distinct triangular area (
Fig. 12
); second and third tergites distinctly and rather finely rugose; foursix tergites granulate; length of ovipositor sheaths 0.37 times of fore wing (
Fig. 16
).

Etymology
.
T. shafeei
is dedicated to Late Dr. S. Adam Shafee from Aligarh Muslim University, Aligarh (
India
) for his valuable contribution to parasitic
Hymenoptera
.
Distribution
.
India
(West Bengal).
Remarks
. The new species
Tropobracon shafeei
Haider
sp.nov.
is closely related to
T. luteus
Cameron
. However
, it differs from
T. luteus
in having (i) face smooth medioventrally and somewhat finely transversally rugulose behind antennal sockets (in
T. luteus
face granulate), (ii) scutellum medioanteriorly with a distinct pit (in
T. luteus
scutellum without pit medioanteriorly), (iii) metapleuron finely punctulate (in
T. luteus
metapleuron finely rugose), (iv) propodeum coarsely granulate (in
T. luteus
propodeum coarsely and densely reticulaterugose, but with a narrow part smooth), (v) vein cua of fore wing interstitial (in
T. luteus
vein cua of fore wing antefurcal), (vi) vein 1rm of hind wing about 2.0 times longer than vein 2SC+R (in
T. luteus
vein 1rm of hind wing about as long as vein 2SC+R), (vii) grooves of second metasomal tergite not meeting each other and not reaching second metasomal suture, resulting without a distinct triangular area (in
T. luteus
grooves of second metasomal tergite reaching second metasomal suture, resulting in a large triangular area).
