“…This analysis was based on morphological characteristics, but the need to test the usefulness of wing dimorphism to establish species limits using breeding and genetic analyses was also discussed. More recently, we employed genetic analyses to support the hypothesis that some brachypterous forms that were previously considered to be separate species are part of fully winged species [55].…”

The hymenopteran subfamily Charipinae (Cynipoidea: Figitidae) consist of a group of parasitic wasps that are exclusive hyperparasitoids of Hemipteran. The species boundaries in Charipinae have historically been unclear. While diagnostic morphological features have been established for the stepwise separation of species, it is recommended to confirm those limits using molecular data. Here, we focus on the genera Alloxysta Förster, 1869 and Phaenoglyphis Förster, 1869, both of which contain species that are hyperparasitoids of aphids. We sequenced three genes (mitochondrial COI and 16S rDNA, and nuclear ITS2 rDNA) from specimens that were identified as belonging to five species: Alloxysta brevis (Thomson, 1862), A. castanea (Hartig, 1841), A. ramulifera (Thomson, 1862), A. victrix (Westwood, 1833), and Phaenoglyphis villosa (Hartig, 1841). The phylogeny resulting from concatenating these genes supported the species status of the five morphologically identified taxa, with P. villosa nested within Alloxysta. Our study thus indicates that these molecular markers can successfully distinguish charipine species, and also indicates that the genera Alloxysta and Phaenoglyphis may be more closely related than previously hypothesized. We also present the first estimates of genetic distances for these species. Future studies that include more species, loci, and/or genomic data will complement our research and help determine species relationships within the Charipinae subfamily.

The subfamily Charipinae (Hymenoptera: Cynipoidea: Figitidae) has had a problematic taxonomic history as many species have been described without comprehensive revisions being undertaken. Reliably identifying these species based on morphological assessment has been almost impossible. Recently, the types of all species have been re-examined and photographed, resulting in numerous taxonomic corrections that have been published elsewhere. Consequently, a summary checklist of all species that have ever been described within the Charipinae is provided with their current accepted status, including all associated references dealing with the historical nomenclatural changes and synonymy. We also provide up-to-date information on the diversity and distribution patterns of Charipinae to assist researchers working on these species in aphid biological control programs.
