Female antenna of Telenomus chandishae sp. n. Male ( Fig. 3 ): Body length = 1.352 mm . Similar to female except for the following characters: Mesosoma, T1 and anterior margin of T2 orangish brown, remainder black; radicle and A1 golden yellow, A2 brownish black, remaining antennomeres black. Vertex patch and frontal patch larger than in female; an additional frontal patch present on medial frons towards inner orbit which extends towards posterior ocelli ( Figs 4 & 10 ); costae on T2 long, extending about half the length of tergite; length and width of antennomeres A1–A 12 in ratio of 18.1:3.6, 5.3:3.3, 6.3:3.4, 6.0:3.3, 6.7:3.5, 7.1:3.6, 7.3:3.6, 6.8:3.5, 7.0:3.5, 6.6:4.0, 6.8:3.6, 9.4:3.3, respectively. Variability: The mean body length of the female was 1.465 mm varying from 1.350 mm to 1.645 mm (SD = 0.09, n = 10). The mean body length of the male was 1.353 mm varying from 1.272 mm to 1.437 mm (SD = 0.06, n = 7). FIGURES 13–18.

This species differs from T. xanthosoma in the following character states: In T. xanthosoma A3 is distinctly longer than A2; A6 longer than wide; A9 and A10 both longer than wide; A3–A11 brown; vertex with shallow coriaceous sculpture throughout; frons smooth; mesoscutum shallowly coriaceous; setal bases weakly not pustulate; hind wing width 2.3× the length of marginal cilia at that point; T1 costate only in basal half. Whereas in Telenomus chandishae sp. n. A3 just 0.68× the length of A2; A6 0.7× as long as wide; A7–A11 black; A9 and A10 distinctly wider than long; vertex medially smooth; frons with at least 2 pairs of transverse furrows above interantennal process; T1 costate almost the entire length of tergite; netrion indicated; mesoscutum entirely smooth; setal bases not weakly postulate; hind wing width 3.8× the length of marginal cilia at that point; T2 with fine punctae in posterior 1/4 th . Etymology: This species is named after Chandish R. Ballal, a good friend and colleague of the authors. The name is treated as a noun in the genitive case. Material examined.
