Characterising the north-western European species of Phaenoglyphis Förster, 1869 (Hymenoptera: Figitidae: Charipinae) with novel insights from DNA barcode data

The taxonomy of the hymenopteran parasitoid subfamily Charipinae (Hymenoptera: Cynipoidea: Figitidae) has, until recently, been in a state of chaos. While this situation has improved significantly in recent years, most of the efforts were focused on morphological data of typically old specimens. Here, we present the first integrative approach to describe the diversity of the genus Phaenoglyphis Förster, 1869 from north-western Europe. For seven (of a total of 17) species, we provide DNA barcode data. Phaenoglyphis belizini Pujade-Villar, 2018 and Phaenoglyphis evenhuisi Pujade-Villar & Paretas-Martínez, 2006 are recorded for the first time from Germany. All DNA barcodes and specimen data were added to the publicly available GBOL and BOLD reference database. The presence of a 6 bp long deletion in the CO1 barcode region that is characteristic to the genus and unique amongst Figitidae supports the monophyly of Phaenoglyphis .
