A NEW GENUS AND SPECIES OF PERILAMPIDAE (HYMENOPTERA: CHALCIDOIDEA) WITH UNCERTAIN PLACEMENT IN THE FAMILY

摘要

A new genus and species of perilampid wasp is described from Yemen and Israel. The features of the adult do not allow for accurate placement within any of the existing subfamilies of Perilampidae. The adults are similar to Chrysolampinae; however, themandibles have a 3/2 formula and although the ventral surface of the male scape has distinct pores, these are not isolated within pits or depressions, which is characteristic of Chrysolampinae and Perilampinae. The labrum is similar to most Perilampinae, but the prepectus is associated with the mesepimeron and not the pronotum. The ovipositor is strongly expanded at the apex and scimitar-shaped, whereas the ovipositor in all other Perilampidae is needle-like. The morphological features that relate to the potential phylogenetic placement of this genus in the perilampid/ eucharitid complex are discussed.
