Dolomedes is a genus of large spiders of the family Pisauridae. They are also known as fishing spiders, raft spiders, dock spiders or wharf spiders. Almost all Dolomedes species are semiaquatic, with the exception of the tree-dwelling D. albineus of the southeastern United States. Many species have a striking pale stripe down each side of the body.
New Zealand has 1157 described spider species, with an estimated total fauna of 2000 species. Over 97 per cent are endemic, and the rest have been introduced through human activities or were natural wind-borne introductions.

Euophrys kawkaban is a species of jumping spider in the genus Euophrys that is endemic to Yemen. The species was first described in 2007 by Wanda Wesołowska and Antonius van Harten. It is a very small spider, with a body that consists of a carapace, the hard upper part of the cephalothorax, that is typically 1.7 mm (0.07 in) long and 1.3 mm (0.05 in) wide and an abdomen that is typically 1.5 mm (0.06 in) long and 1.1 mm (0.04 in) wide.

Euophrys falciger or the Drakensberg Euophrys Jumping Spider is a species of jumping spider in the genus Euophrys that is endemic to South Africa, living in KwaZulu-Natal. The species was first described in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith. Its name recalls the sickle-shaped embolus of the male. The spider is small, with a body that consists of an oval cephalothorax that measures between 1.1 and 1.9 mm long and a narrower abdomen that is between 1.2 and 1.8 mm long. The male is significantly larger than the female, and darker. Its carapace, the topside of the cephalothorax, is dark brown and the underside of the cephalothorax, or sternum, is black, while its abdomen is black with a pattern of light patches on top and dark underneath. In comparison, the female abdomen is greyish-brown on top and yellowish underneath, The male has generally dark brown legs, while the female's legs are greyish-yellowish. The female is similar to others in the genus, although differing in aspects of its copulatory organs. The male is easier to distinguish without close examination. For example, as well as its longer embolus, it is its smaller size that helps differentiate it from Euophrys meridionalis.
Euophrys subtilis is a species of jumping spider in the genus Euophrys that is endemic to South Africa. The species was first described in 2014 by Wanda Wesołowska, Galina Azarkina and Anthony Russell-Smith.

The carapace, the topside of the cephalothorax, is dark brown and the underside of the cephalothorax, or sternum, is a lighter brown. The pattern on the abdomen differs between the female and the male. The female has a creamy-white surface that is marked with dark spots. The male has a brown band across its brownish-grey surface. They have brown legs. The copulatory organs enable the spider to be distinguished from other species in the genus. The male has a long thin embolus on its palpal bulb, although not as long as Euophrys nana. The female has wide insemination ducts that loop in the middle and spherical spermathecae.
Anoteropsis hilaris, commonly referred as the garden wolf spider or the grey wolf spider, is a species of wolf spider that is endemic to New Zealand.
