Host information.

Host of type unknown; also Plutellidae : Plutella armoraciae Busck, 1912, Plutella xylostella (Linnaeus, 1758).

Notes.

German specimens were identified based on the detailed species concept in Fernandez-Triana et al. (2014b). One of the hosts currently associated with this species, Plutella xylostella , has been widely reported in the literature (e.g., Papp 1981b; Fernandez-Triana et al. 2014a) and the wasp is commonly reared from it. Our sequences match specimens reared from P. xylostella (CNCHYM 01692, CNCHYM 01693, CNCHYM 01694) in Canada and a sequence from another specimen from the Netherlands (CNCHYM45357=MRS_JFT0220) also reared from the same host; the maximum p-distance for those specimens and the German material is 0.82%. Specimens of this species cluster in two BINs which are separated by 2.14% but also show a high within-BIN variability of 2.28% and 2.64%. A second host species, Plutella armoraciae , has been recently recorded for this wasp in Canada ( Abram et al. 2022). The reared wasps are not yet sequenced. Whether D. claritibia represents a single species or a complex of morphologically cryptic species is beyond the scope of the present paper and will need further study including more (reared) specimens from both the Palearctic and the Nearctic. The hosts were first recorded by Papp (1981b) and Abram et al. (2022). The distribution of this species in Germany was mentioned by Papp (1981b), but to our knowledge not cited in literature since, so we confirm it here. Additionally, we add the distribution for Syria, which was also mentioned by Papp (1981b), but not cited since. Finally, we correct the distribution from the world checklist and add the records from Cyprus, France, Italy, Jordan, and the Netherlands reported by Fernandez-Triana et al. (2014b). This species is illustrated in Fig. 49 .
