Geographical distribution.

Molecular data.

BOLD:AAC9130.

Host information.

Momphidae : type reared from Mompha raschkiella (Zeller, 1839).

Notes.

German specimens were identified by comparing to the original description ( Shaw 2012a). BIN BOLD:AAC9130 probably includes more than one species. This BIN includes two haplotype clusters (Fig. 36 ) separated by seven mutations. Cluster A includes specimens from the United Kingdom identified by the original author of the species and reared from the same host as the holotype (CNCHYM45380=MRS_JFT0192). Our specimens collected from Germany cluster with these authoritatively identified specimens and match the species morphologically with some minor differences. We consider them Microgaster raschkiellae and report this species for Germany for the first time. Cluster B likely represents a different species from the Nearctic, but exploring this further is beyond the scope of this project. This species is illustrated in Fig. 37 .

Figures

Figure 36. TCS haplotype network of BIN BOLD: AAC 9130, the haplotypes morphologically identified as Microgaster raschkiellae as part of this project are in cluster A and marked by a grey background. Each hatch mark in the network represents a single mutational change; small black dots at nodes indicate missing haplotypes. The diameter of the circles is proportional to the number of haplotypes sampled (see legend). The aligned sequences and traits can be reviewed in Suppl. materials 12, 13.
