Thoreauella Girault 

( Fig. 16View FIGURE 16)

This is the first record of Emargininae  from New Zealand. Emargininae  are characterised by having a deeply bilobed forewing. The only other cynipoid genus in New Zealand with a bilobed forewing is Kleidotoma  . Thoreauella  has a narrow, rhomboid scutellum with prominent lateral carinae, whereas the scutellum in Kleidotoma  is tear-drop shaped.

Only ten specimens of Emargininae  exist in the NZAC, but these are from widespread locations. North Island: AK, GB, HB, ND, WI. South Island: NN. Six specimens were collected as part of a large scale survey of pasture ( Cumber 1959) but had been misidentified as Kleidotoma  . It is uncertain if these specimens represent an adventive or a native species. Thoreauella  are associated with ants, and are probably parasitoids of dipteran larvae in ant nests or refuse deposits ( Ronquist 1999). The New Zealand ant fauna is very small ( Ward 2009) and ants have been very well collected, so it surprising not to have more records of Thoreauella  .
