Brasil; [email protected] Edited by Fernando B Noll – UNESP Received 26 August 2010 and accepted 05 December 2010 A recent reclassiication of Eulophidae based on molecular coloration of their bodies, while other species of Elasmus data and phylogenetic analyses has demonstrated that are predominantly dark-colored, and by biological Elasmidae must now be considered a tribe of Eulophidae peculiarities such as the creation of a transversal (Gauthier et al 2000). In such way, the only normally partition in the host cell composed by light brown to recognized genus of Elasmidae, Elasmus, is now classiied black pellets around the inner sides of the cell. This as pertaining to Eulophinae, tribe Elasmini, representing partition seals off the parasite from the host remains about 200 described species (Noyes 1998). Elasmus is preventing contamination from Polistes meconia and cosmopolitan in distribution, although most abundant body remnants (Reed & Vinson 1979, Gumovsky et al in the Old World tropics, and species are characterized 2007). by their small size (hardly bigger than 1-3 mm), brown Elasmus sp. has been registered in several states or black to yellow body coloration, widened hind coxae, of Brazil, such as Mato Grosso, São Paulo and Ceará, and hind tibia with waved lines or patterns in diamond but records of species parasitizing hymenopterans shape. are available only for Elasmus languidus De Santis on Elasmus are in their majority parasitoids of Apanteles galleriae Wilkinson (Braconidae) in São Lepidoptera, although some Hymenoptera, particularly Paulo (De Santis 1980), Elasmus maculatus Howard on Braconidae and Ichneumonidae, are also recorded Apanteles americanus Lepeletier (De Santis 1979), A. as hosts (Gibson 1993). There is also a group of ϔlaviventris Cresson, A. leucostigmus Ashmead (Thompson species described as parasitoids of Polistes wasps 1954), Iphiaulax sp. (Braconidae) (Herting 1977) and (Hymenoptera: Vespidae), such as Elasmus schmitti Psychidosmicra sp. (Chalcididae) (De Santis 1979) in Ruschka and Elasmus biroi Erdös in Western Europe, Ceará hosts. Elasmus japonicus Ashmed in eastern Paleartic, and In here, we irst report the occurrence of Elasmus Elasmus polistis Burks in North America. These species polistis Burks in nests of Polistes versicolor (Olivier) in of Elasmus are characterized by the intense yellow Brazil and in the State of Rio Grande do Sul.
