(2 species) in Brazil. The parasitoid Pachycrepoideus vindemmiae (Rondani) is associated for the first time in Brazil with a Neosilba species.  Key words:  Neosilba, Lonchaea, Pachycrepoideus vindemmiae   RESUMO  Neste trabalho registram-se novos hospedeiros para Neosilba pradoi Strikis & Lerena (3 espécies), Neosilba certa (Walker) (espécie 1) e Lonchea sp. (espécie 2) no Brasil. O parasitoide Pachycrepoideus vindemmiae (Rondani) é associado pela primeira vez no Brasil com uma espécie de Neosilba.   Palavras-chave: Neosilba, Lonchaea, Pachycrepoideus vindemmiae   Surveys of hosts of Lonchaeidae (Diptera) are recent and scarce in Brazil. Studies of this nature are important in understanding the ecology of lonchaeid species, especially because some of them are reported as agricultural pests (Strikis et al. 2011). Between December 2010 and November 2011, fruits were collected at random from potential hosts of Lonchaeidae in Passo Fundo, State of Rio Grande do Sul, Brazil (28°13’S, 52°26’W). We collected ripe fruits (off the plants or from recently fallen ones) from six plant species (Table 1). The fruits were counted, weighed and stored in screen-covered plastic trays containing vermiculite and kept at room temperature. The substrate was sifted daily and the obtained puparia were stored in flasks containing moist vermiculite. The emerged adults were preserved in 70% ethanol for identification. We obtained specimens of Neosilba pradoi Strikis & Lerena, Neosilba certa New host records of Lonchaeidae (Diptera) in Brazil and associated parasitoid  117 (Walker), and Lonchaea sp. (Diptera: Lonchaeidae), as well as Pachycrepoideus vindemmiae (Rondani) (Hymenoptera: Pteromalidae) (Table 1). This work reports the following hosts for the first time in Brazil: Inga vera Willd., Passiflora elegans Mast., and Passiflora caerulea L. as hosts of N. pradoi; I. vera as host of N. certa; P. elegans and P. caerulea as hosts of Lonchaea sp. The only past reports of Neosilba pradoi on Passifloraceae and Fabaceae were in Passiflora edulis and Inga laurina, respectively (Strikis & Lerena 2009). Also in Fabaceae, the only known host of N. certa was Inga velutina (Strikis et al. 2011). As regards Passifloraceae hosts of Lonchaea sp., the only known host was P. edulis (Garcia & Norrbom 2011). This work associates the parasitoid P. vindemmiae to a species of Neosilba (N. pradoi) for the first time in Brazil. This parasitoid species has already been associated with Tephritidae recovered from fruits of Prunus persica (Rosaceae) in the State of São Paulo (Montes et al. 2011). We suggest that more extensive and intensive surveys of Lonchaeidae hosts be completed in the State of Rio Grande do Sul and across Brazil, both in agricultural areas and in regions without significant human alteration, so as to enhance the available knowledge on the ecology of this important dipteran family.
