Trichogramma fasciatum ( Perkins, 1912)

Diagnosis. Distinguished by small oval genital capsule; dorsal lamina covering volsellae and intervolsellar process.

Comments. Trichogramma fasciatum was erroneously identified by several authors (see Pinto et al. 1978, 1983). Therefore, only the records published after these articles by Pinto and colleagues are considered to actually refer to this species. Trichogramma fasciatum showed considerable morphological variation, with intermediate forms (details in Pinto 1999). Based on microscope slide preparations loaned by C. Korytkoviski, deposited in the ESALQ collection, and figures from the article by Ruiz & Korytkoviski (1979), we concluded that the records of T. fasciatum reported by these authors are misidentifications. The specimens discussed by these authors correspond to T. fuentesi . Specimens from Peru identified as T. fasciatum by R. B. Querino belong to T. exiguum ( Querino & Zucchi, 2003b) . Therefore, we also consider that T. fasciatum has not been recorded in Peru so far. Similarly, the record of T. fasciatum in Venezuela, as listed in De Santis (1981), requires additional information to be confirmed. However, this species was recorded in Venezuela by Velásquez & Terán (2003).
