Doddifoenus wallacei, a new giant parasitoid wasp of the subfamily Leptofoeninae (Chalcidoidea: Pteromalidae), with a description of its mesosomal skeletal anatomy and a molecular characterization

Abstract

A third species of Doddifoenus Bouček (Pteromalidae: Leptofoeninae), is described from Laos and Thailand. Doddifoenus wallacei sp. n. is the first species of the genus occurring west of Wallace’s Line, and with a body length of up to 4.2 cm it is among the longest known of any chalcidoid wasp. A differential key and distribution map for the world species of Doddifoenus are given. A detailed description of the mesosoma, including external and internal features, and molecular data (D2-D5 fragments of the 28S gene) are provided to facilitate future phylogenetic analyses. The phylogenetic placement of Leptofoeninae is briefly discussed, especially with respect to the pteromalid subfamilies Pteromalinae and Cleonyminae.
