( Figure 3 View Figure 3 )

Material examined

Holotype. Male, Philippines, “Pilipinas, Luzon Sierra Madre Nuevaecija, Mar. [19]65 A. Villareal ” ( CNCI).

Morphology

Length of body 12.8 mm, length of fore wing 12.7 mm. Antenna with 92 flagellomeres. Raised median area of first tergite not depressed medially. Fore wing vein cu-a virtually interstitial. Fore wing second submarginal cell elongate, vein 2-M 3.45 times length of 2-SR. Hind wing vein 2-SC+R interstitial. Hind wing sub-basal cell glabrous on posterior half and with large glabrous area distal to vein cu-a.

Coloration

Antennae, body and legs orange-yellow except for the following: basal six flagellomeres piceous to black, scapus laterally, middle of frons, stemmaticum and area around stemmaticum not reaching the eye, hind femur ventro-distally, black. Wings pale yellow, with distal margin grey and fore wing with small black spot at apex and at base of pterostigma.

Etymology

Named after Professor Claire Baltazar who first recognized Ischnobracon as a new genus.

Notes

This is the only species known to date only from a male specimen, and males of the other known species are exceedingly rare. Therefore, adjudging that this specimen represents a distinct species is based on its unique colour pattern and that it is the only largely yellow species with a large glabrous area distal to hind wing vein cu-a. The other predominantly yellow species known from the Philippines is I. bakeri and, although both species have extensively yellow antennae (more so in I. baltazarae sp. nov.) and have the black mark on the top of the head reduced, not reaching the margin of the eyes, the new species differs from it in having the base of the hind wing with a large glabrous region and in having a black mark on the disto-ventral surface of the hind femur.
