ALAGOAS: Maceió, April 2000 , ex egg of Calpodes ethlius on Canna spp., Iracilda M.M. Lima collr. ( ESALQ ). Seventeen paratypes (males) with same data as holotype ( ESALQ ). Two paratypes (males) with same data as holotype (UCR). DIAGNOSIS ­ Trichogramma iracildae is distinguished by the broadly separated and laterally placed ventral processes and the usually bifid intervolsellar process. This character is also observed in T . marthae , but the intervolsellar process is different. Other important characteristics in T . iracildae are the wide genital capsule and the short and apically rounded posterior extension of the dorsal lamina. Samples of T . iracildae were anlysed for ITS2 sequence of the r­DNA and the results showed it to be different from that of any other species known previously (Raul P. Almeida, pers. com.). VARIATION ­ Unsocketed setae present in the first section of the flagellum; basiconic sensilla varying in number in the position 2; setae of the posterior track reaching the apex of the wing; intervolsellar process bifid in 12 of the 19 specimens studied. ETYMOLOGY ­ The species is named after Professor Iracilda M. M. Lima (UFAL), the collector of the type series.
