Named for Claire Villemant, entomologist and Curator of the hymenopteran collections of MNHN, for her invaluable support. Distribution records. Reunion . Genus Exoryza Mason (Mason 1981, Valerio et al. 2004) The description of Dolichogenidea is similar to Exoryza , but with the following differences. Propodeum coarsely rugose with an areola sometimes hardly defined laterally. Terga 1 and 2 broad, covering the membranous lateroterga in dorsal view. Terga 1 and 2, and usually tergum 3, coarsely rugose. Tergum 2 rectangular or nearly so, as long to barely longer than tergum 3. This is a small genus, with four species described up to now. It appears to parasitise Pyraloidea stem borers. It is rarely collected but appears to be broadly distributed. This is the first record from Southern Hemisphere. It is considered as a distinct genus with four recognized species based on the peculiar structure of the metasomal terga (Song and Chen 2003; Valerio et al. 2004). It nevertheless matches a wide definition of Dolichogenidea / Apanteles and is sometimes considered as a subgenus of Apanteles . One new species is decribed here.
