Notes

The host specimen could not be precisely identified using either morphology or the Species Level Barcode Record search of the sequence library available on BOLD at the time of this writing. A more general search of BOLD using the All Barcode Records search option returned a closest match (95.26% similarity) with the dictynid Nigma walckenaeri . A query of Genbank returned a closest match (88%) with Dictyna latens . A calamistrum is visible on the fourth metatarsus of the presereved host specimen (Fig. 17). The calamistrum is an organ involved in the spinning of cribellate silk ( Köhler and Vollrath 1995, Opell 1998). The presence of a cribellum alone eliminates the vast majority of European spider taxa. In combination with the overall size and shape, we conclude this host belongs to the spider family Dictynidae. The World Ichneumonoidea database on Taxapad indicates that Zatypota anomala (Fig. 20) has been associated with dictynid spider hosts ( Yu et al. 2012). The incompletely identified host DNA barcode sequence has been deposited in BOLD. As the library of reference sequences grows, it may become possible to identify this host to species. An attempt to barcode the parasitoid Zatypota anomala was not successful.
