Mimetus is a genus of pirate spiders in the family Mimetidae. [1] They are found worldwide.
Members of this genus resemble the comb-footed spiders, Theridiidae, due to their globular abdomen. The upper side of this bears curved bristle-like hairs. A distinguishing mark of the genus is that the distance between the anterior edge of the carapace and the anterior medial eyes is about one-third to one-half of the distance between the anterior and posterior medial eyes. The length of the anterior legs is about 1.5-1.7 times that of the posterior pair. [2]
Spiders in this genus are specialised spider killers. They spin no web but are slow moving, stalking or ambushing their prey. They sometimes invade the web of their potential victim, vibrating the silk to mislead the owner. An individual will attack a potential victim by biting one of its legs and injecting toxins. It then retreats and the prey spider quickly becomes paralysed. The attacker then advances and starts to feed, sucking out the body fluids of its victim. [2] [3]

Recently, two new species were discovered in Western Ghats, India, namely, M. spinatus and M. parvulus. [4]
Castianeira is a genus of ant-like corinnid sac spiders first described by Eugen von Keyserling in 1879. They are found in Eurasia, Africa, and the Americas, but are absent from Australia. Twenty-six species are native to North America, and at least twice as many are native to Mexico and Central America.
Micrathena, known as spiny orbweavers, is a genus of orb-weaver spiders first described by Carl Jakob Sundevall in 1833. Micrathena contains more than a hundred species, most of them Neotropical woodland-dwelling species. The name is derived from the Greek "micro", meaning "small", and the goddess Athena.
Hogna is a genus of wolf spiders with more than 200 described species. It is found on all continents except Antarctica.
Tmarus is a genus of crab spiders, comprising 227 species:
Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and it contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them. The name Tetragnatha is derived from Greek, tetra- a numerical prefix referring to four and gnatha meaning "jaw". Evolution to cursorial behavior occurred long ago in a few different species, the most studied being those found on the Hawaiian islands. One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.
Olios is the largest genus of huntsman spiders, containing 166 species. They are found throughout the world, with most species occurring in hot countries. The genus was first described by Charles Athanase Walckenaer in 1837.
Dictyna is a genus of cribellate araneomorph spiders in the family Dictynidae, and was first described by Carl Jakob Sundevall in 1833.
Synema is a genus of spider in the family Thomisidae, found in most parts of the world.
Miagrammopes is a genus of cribellate orb weavers first described by Octavius Pickard-Cambridge in 1870. These spiders have a unique shape and only four of their original eight eyes. They spin a single line of web, actively watching and jerking the line to catch their prey.
Trachelas is a genus of araneomorph spiders which has variously been placed in families Trachelidae or Corinnidae. Current taxonomy places it in Trachelidae.
Eustala is a genus of orb-weaver spiders first described by Eugène Simon in 1895.
