Nysíus caledoniae Distant, 1920 (Hemiptera: Heteroptera: Orsillidae) a recent introduction into New Zealand, and keys to the species of Nysius, and genera of Orsillidae, in New Zealand

摘要

Nysius caledoniae Distant, 1920 is recorded for the first time as an alien introduced species in New Zealand. Collection with young stages indicates that it may already have established itself in Auckland. Characters of the species enabling its identification are presented. The pest-status of N. caledoniae, N. vinitor Bergroth, 1891, and N. huttoni White, 1878, is reviewed. A key to the genera of Orsillidae in New Zealand is provided, along with a revised key to the species of Nysius in that country.
