Trichogramma parrai Querino & Zucchi , new species ( Figures 1c , 2c )

Antenna: flagellum long (0.18 0.010); ratio of the length to width of flagellum (7.87 0.72); flagellum length to hind tibial length (1.09 0.04); flagelliform setae long (0.08 0.006), evenly tapering to apex; flagelliform setae length to flagellum width (3.59 0.36); several unsocketed setae on the flagellum; basiconic sensilla prominent and globose, formula 2­2­2­0­1­1; three placoid sensilla, the basal one 0.05 0.004. Forewing: width to length ratio forewing (0.57 0.02); fringe setae short (0.03 0.003); fringe setae length to hind tibial length (0.17 0.02); fringe setae length to forewing width (0.09 0.01); 4­13 setae between the 4 th and 5 th setal tracks. Hind wings: few setae; anterior track absent; posterior with 3­5 setae, not reaching the mid­point of the middle track. Scutellum: anterior setae relatively long; ratio of anterior to posterior pair (0.29 0.14). Male genitalia: genital capsule longer (0.15 0.006) than wide (0.05 0.003); ratio of the width to length of the genital capsule (0.35 0.02); apical distance to genital capsule length (0.26 0.02); apical width to genital capsule width (0.73 0.06); dorsal lamina with basal notching; dorsal lamina length to dorsal lamina width (1.93 0.19); dorsal lamina length to genital capsule length (0.44 0.03); dorsal aperture length to dorsal lamina length (1.32 0.10); posterior extension of the dorsal lamina long (0.05 0.007), which is narrow, linguiform and extending beyond the volsellae; posterior extension of dorsal lamina length to dorsal lamina length (0.78 0.07); dorsal ridge absent; ventral ridge long (0.07 0.03), extending beyond the midpoint of the genital capsule; ventral ridge length to basal distance (0.64 0.01); basal distance to genital capsule length (0.74 0.02); ventral processes occur considerably close to the base of the base do intervolsellar process, which is long (0.02 0.002), pointed or slightly rounded apically. Quantitative data were obtained from four males.

TYPE MATERIAL ­ Holotype male. BRASIL. SÃO PAULO: Piracicaba, Tupi (forest reserve), suction trap, R. B. Querino collr. ( ESALQ). Two paratypes (males) ( ESALQ) and one paratype (male) ( UCR), with same data as holotype.

DIAGNOSIS ­ Trichogramma parrai is characterized by the prominent and globose basiconic sensilla, several unsocketed setae on the flagellum, the weakly lobed dorsal lamina with shoulders not approaching the sides of the genital capsule and the linguiform, elongate posterior extension, which is extends beyond the volsellae. T. parrai may be remotely related to T. stampae and T. nemesis (John D. Pinto, pers. com.) by having dorsal lamina sides tapering posteriorly to form a linguiform posterior extension whose width at base of intervolsellar process is subequal to aedeagus. However, based on the characters commented by Pinto (1999) ­ posterior extension of the dorsal lamina more short and a distinct shoulders, which in T. nemesis is more distinctive and attain the sides of the genital capsule ­ T. stampae and T. nemesis are easily separated from T. parrai , which has a more elongate posterior extension and weakly lobed dorsal lamina with shoulders not approaching the sides of the genital capsule.

ETYMOLOGY ­ The species is named after Prof. José Roberto Postali Parra for his contribution to the biological studies on Trichogramma in Brazil.
