Material examined. BRAZIL. MINAS GERAIS: Lavras, 10.v.1984, 1 male, ex eggs of Erinnyis ello on Hevea brasiliensis (D. Pratissoli collr.), Janaúba, 9.iii.2010, 1 male, ex eggs of Erinnyis ello on Manihot esculenta Crantz (J. M. Vieira collr.); SÃO PAULO: Campinas, 01.vi.1985, 1 male, ex eggs of Erinnyis ello on Manihot esculenta (W. Reis collr.); PARANÁ: Marechal Cândido Rondon, 12.XII.2001, 5 male, ex eggs of Erinnyis ello on Manihot esculenta (V. Pietrowski collr.) (ESALQ).
Diagnosis. Trichogramma manicobai is the most easily recognized South American species. It is identified by the wide genital capsule, especially the dorsal lamina with lateral projections, and the short wide intervolsellar process with a truncated or bifid apex.
Description. Male. Based on field-collected specimens from host. Quantitative data taken from 8 males (HTL = 175.0 ± 4.3 µm). Color of living specimens yellowish brown.
Antenna. Flagellum relatively short (141.5 ± 6.0), FL/FW = 3.41 ± 0.18; FL/HTL= 0.81 ± 0.03; flagelliform setae short (57.1 ± 2.2), with abruptly tapered apex; FSL/FW = 1.38 ± 0.09; placoid sensilla, terminal PLS = 48.3 ± 1.7.
Wings. Forewing not infuscate behind venation; FWW/FWL = 0.54 ± 0.01; fringe setae = 30.7 ± 0.9; ca. 0.18 x HTL, 0.11 FWW; 10-26 setae between 4th and 5th setal tracks. Anterior track of hind wing with 2 setae, posterior track with 7 to 8 setae, reaching midpoint of middle track.
Scutum/Scutellum. Scutellum with anterior pair of setae 0.3 length of posterior pair.
Genital capsule. Genital capsule 0.57 ± 0.02 as wide as long; AD elongate with AD/GL = (0.30 ± 0.01); AW/ GW = (0.61 ± 0.03); DLA with lateral projections extending beyond margin of genital capsule, DLA (0.65 ± 0.02) as long as wide, DLA/GL = 0.33 ± 0.01; AD/DLA =1.97 ± 0.07; posterior extension of DLA long, 34.2 ± 0.9, with pointed apex, exceeding apex of VS. VR long (50.3 ± 1.8), occupying ca. 0.56 BD; BD/GL = 0.30 ± 0.01; IVP short, pointed apically, usually with truncated apex and sometimes bifid. VP positioned near base of IVP; AL/HTL = 0.38 ± 0.02; apodemes 1.09 AL.
Distribution. Brazil: Mato Grosso do Sul, Minas Gerais, Paraná, Piauí and São Paulo.
Remarks. Specimens of T. manicobai show intraspecific variations in the apex of the intervolsellar process (truncated or bifid), and the apex of the dorsal lamina (rounded, or pointed and bifid). The type material shows variation in the length of the flagelliform setae relative to the width of the flagellum (Zucchi 1985). In the specimens from Lavras, the proportion of the adeagus to the apodemes is slightly smaller than of specimens in the type series.
