Trichogramma tupiense Querino & Zucchi, 2003

Querino, R. B. & Zucchi, R. A., 2003, Six new species of Trichogramma Westwood (Hymenoptera: Trichogrammatidae) from a Brazilian forest reserve, Zootaxa 134 (1), pp. 1-11 : 8-9

Trichogramma tupiense Querino & Zucchi , new species ( Figures 1e , 2e )

Antenna: flagellum long (0.18 0.02); ratio of the length to width of flagellum (7.71 0.84); flagellum length to the hind tibial length (1.12 0.08); flagelliform setae long (0.08 0.01), evenly tapering to apex; longest flagelliform setae length to flagellum width (3.55 0.28); unsocketed setae situated basally on flagellum (absent in four specimens); basiconic sensilla with formula 2­2­2­0­1­1; three placoid sensilla, the basal one 0.04 0.00. Forewing: width to length ratio of the forewing (0.51 0.02); fringe setae length to hind tibial length (0.26 0.03); fringe setae length to forewing width (0.16 0.02); 6­13 setae between the 4 th and 5 th setal tracks. Hind wings: anterior track absent; posterior track with few setae (2­4), the latter not extending beyond half the length of the middle track. Scutellum: anterior setae relatively elongate; ratio of anterior setae to posterior pair (0.19 0.04). Male genitalia: genital capsule longer (0.12 0.01) than wide (0.04 0.00); ratio of the width to length of the genital capsule (0.33 0.02); apical distance to genital capsule length (0.24 0.01); apical width to genital capsule width (0.71 0.02); dorsal lamina length to dorsal lamina width (1.52 0.18); dorsal lamina length to genital capsule length (0.41 0.04); dorsal lamina gradually tapers from base to apex; posterior extension of the dorsal lamina long (0.04 0.00), approaching the volsellae and pointed at apex; posterior extension of the dorsal lamina length to dorsal lamina length (0.72 0.03); dorsal aperture length to dorsal lamina length (1.39 0.19); dorsal ridge absent; ventral ridge indistinct (anterior limits difficult to discern under light microscope); basal distance length to genital capsule length (0.76 0.01); ventral processes distinct placed at base of the intervosellar process, which is relatively short and distinctly less than half the length of volsellae. Quantitative data were taken from eight males.

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

DIAGNOSIS ­ Trichogramma tupiense is distinguished mainly by the placement of the distinct ventral processes at or very near the base of the intervolsellar process, and by the indistinct basal notching of the dorsal lamina. These characters separate T. tupiense from the other South American species. However, T. tupiense is closer to T. bruni , a species recorded in Brazil and Venezuela, but T. tupiense differs by having the more elongate intervolsellar process, more distinct ventral processes and their placement very near the base of the intervolsellar process, shorter and less distinct ventral ridge and anterior setae relatively elongate. In T. bruni , intervolsellar process are short, ventral processes are distinctly anterior to the intervolsellar process, the ventral ridge is longer and extending beyond the middle of the genital capsule, and the anterior setae of the scutellum are shorter.

ETYMOLOGY ­ The scientific name is a neo­latin adjective derived from Tupi, the name of the forest reserve where the species was collected.
