Abstract

Species of the wasp family Rhopalosomatidae are parasitoids of crickets. The last revision of this family was completed 30 years ago. Since then, with many more specimens collected by Malaise traps, an update of existing descriptions and keys has been made possible. New generic characters have been added to the description for Paniscomima Enderlein. Four new species of Paniscomima are described: P. angelae, sp. nov., P. darlingi, sp. nov., P. lottacontinua, sp. nov., and P. paropposita, sp. nov. The first descriptions of male P. seyrigi (Berland) and female P. opposita Townes and a key to the species of Paniscomima are provided. A cladistic analysis was performed to determine the relationships among the 11 nominal species of Paniscomima. Sixteen morphological characters were used in the analysis and exemplars from the genus Rhopalosoma were used as outgroup taxa. The phylogenetic analysis supports a South-east Asian clade with a sister species from Madagascar and a basal polytomy of species occurring in Africa (including Madagascar).
