Wolf spiders are members of the family Lycosidae, from the Ancient Greek word "λύκος" meaning "wolf". They are robust and agile hunters with excellent eyesight. They live mostly in solitude and hunt alone, and do not spin webs. Some are opportunistic hunters pouncing upon prey as they find it or even chasing it over short distances. Some wait for passing prey in or near the mouth of a burrow.
Tree trunk spiders (Hersiliidae) is a tropical and semi-tropical family first described by Tamerlan Thorell in 1870. They have two prominent spinnerets that are almost as long as their abdomen, earning them the nickname "two-tailed spiders". They range in size from 10 to 18 millimetres long. Rather than using a web that captures prey directly, they lay a light coating of threads over an area of tree bark and wait for an insect to stray onto the patch. When this happens, they encircle their spinnerets around their prey while casting silk on it. When the insect is immobilized, they can bite it through the shroud.
Cedicoides is a genus of spiders in the family Cybaeidae made up of four species. It is characterized by well developed tegulum on the bulb of the male pedipalp. When it was published by Charitonov in 1946, it acted as a subgenus to Cedicus. Later, it was argued that the differences between spiders of Cedicoides and those of other subgenera - notably the presence of a terminal apophysis and the shape of the male pedipalp - were great enough to warrant a new genus. In 2003, it was upgraded from subgenus to genus status by Marusik & Guseinov. Spiders of this genus are rare, and are often missing from spider collections taken from these regions during any time other than their mating season.
