Figure 4. Automontage ® photomicrographs of features of Ischnobracon feliciae sp. nov. (A) Head and anterior of mesosoma, showing dark marks on the three lobes of mesoscutum; (B) face, frontal view, showing black triangular area above clypeus; (C) head and anterior of mesosoma, lateral aspect; (D) apex of hind tibia and tarsus.

(A) Habitus dorsal view, showing general colour pattern; (B) fore wing second submarginal cell; (C) apex of metasoma, lateral aspect; (D) metasoma, dorsal view. Material examined Holotype . Female Philippines , “P.I. Palawan 6.4 km N. of Tarumpitao Pt., 30. V.1958 ”, “[caught] in jungle”, “ H. E. Milliron Collector. ” “ Holotype Ischnobracon gressitti Baltazar ′63” ( BPBM ). Morphology Length of body 12 mm , of fore wing 11.5 mm and of ovipositor 9 mm . Antenna with 107 flagellomeres. Raised median area of first tergite not conspicuously depressed medially. Fore wing vein cu-a distinctly postfurcal. Second submarginal cell strongly expanded distally, vein 2-M 3.4 times longer than 2-SR. Base of hind wing with sub-basal cell largely glabrous and with large glabrous area distal to vein cu-a. Vein 1-SC+ R interstitial. Figure 6. Automontage ® photomicrographs of features of Ischnobracon gressitti Baltazar. (A) Habitus showing general colour pattern; (B) head and anterior of mesosoma, dorsal view; (C) antennae, head and anterior of mesosoma, lateral view showing extensively pale-coloured antennae. Figure 7. Automontage ® photomicrographs of features of Ischnobracon gressitti Baltazar. (A) Head and mesosoma, lateral aspect; (B) face, oblique aspect, showing square black mark; (C) metasomal tergites 1 and 2, lateral aspect; (D) fore wing second submarginal cell; (E) base of hind wing showing large glabrous area distal to vein cu-a. Colouration Head yellow with square mark on face as well as mid-longitudinal stripe on upper part, frons medially and vertex and occiput black. Meso- and metasoma black except for a few dark brown-black marks and apical half of antenna which is brown yellow, fore and middle legs which are cream yellow, the latter with distinct dark brown mark on coxa and baso-ventral part of femur. Wings smoky yellow with distal margin grey brown. Notes Closely related to I. laboriosus and I. albitarsus sp. nov. differing from both in being almost entirely black and in having the antennae yellowish distally.
