- Summary
- Compared with the species of Nysius from other parts of the World, the New Zealand species are amongst the most extraordinary because of brachyptery, and a full single or double row of punctures following the claval suture. One new species, the smallest Nysius known, is described and figured. The species described as Brachynysius convexus Usinger 1942 is reinstated, the macropterous form is described, and both forms are figured. Three species in this genus are now recognised in New Zealand; the main distinguishing characters are given, the male and female genitalia figured, the relationship to overseas species indicated, notes on distribution and habits are given, and a key to the New Zealand species is provided.
