Three species of Trichogramma, T. rabindrai, T. pieridis and T. giriensis have been described as new. The first species was reared from the eggs of a sphingid on a marshy weed bordering paddy fields at Someshwar and Saligrama in Udupi District, the second one from those of a pierid on Cassia fistula at Balehonnur, Chickamagalur District (both Karnataka) and the third from unidentified lepidopterous eggs on bamboo leaves at Tusharagiri (Kerala). The taxonomic significance of scutellar bristles, RS1 row of setae in the forewings and setal arrangement in the hind wings are discussed. A key to differentiate the three newly described species from other closely resembling ones has been included.

Abstract


Three species of Trichogramma, T. rabindrai, T. pieridis and T. giriensis have been described as new. The first species was reared from the eggs of a sphingid on a marshy weed bordering paddy fields at Someshwar and Saligrama in Udupi District, the second one from those of a pierid on Cassia fistula at Balehonnur, Chickamagalur District (both Karnataka) and the third from unidentified lepidopterous eggs on bamboo leaves at Tusharagiri (Kerala). The taxonomic significance of scutellar bristles, RS1 row of setae in the forewings and setal arrangement in the hind wings are discussed. A key to differentiate the three newly described species from other closely resembling ones has been included.
