Distribution in New Zealand

Table 2 summarises the known distribution of the species of Encyrtidae on the two main islands of New Zealand. It can be seen that about 60% of the species thought to be endemic are found on both the North and South islands, whereas about 25% have been found on the South Island only and 15% on the North Island only. Of those found on the South Island only, Rhopus anceps, Notodusmetia coroneti, and perhaps also Adelencyrtoides tridens are exclusively associated with alpine or subalpine habitats; the others are associated mainly with native forests. Of the endemic species recorded solely from the North Island, only Genus A may be restricted to alpine habitats. It must be pointed out that these data probably reflect the intensity of collecting in the various parts of New Zealand to a greater extent than the actual distribution of the species.

Table 2. Summary of the known distrubution of the species of Encyrtidae on the North and South Islands of New Zealand. The introduced species Leptomastidea abnormis and Copidosoma koehleri are not included because they appear to have failed to establish, and C. desantisi because it was not released.

Table 3 summarises the known components of the encyrtid fauna of the main offshore and subantarctic islands. Again, these data probably reflect collecting effort rather than the numbers of species actually occurring on each island.
