Hersiliidae is a tropical and subtropical family of spiders first described by Tamerlan Thorell in 1869, which are commonly known as tree trunk spiders. They have two prominent spinnerets that are almost as long as their abdomen, earning them another nickname, the "two-tailed spiders". They range in size from 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. Diversity Hersiliidae is an entelegyne family (characterized primarily by the nature of the female genital system), and together with the family Oecobiidae traditionally formed the superfamily Oecobioidea. The family consists of about 206 species divided into sixteen genera. It has a global distribution in tropical and subtropical regions, with ...

Tamopsis
''Tamopsis'' is a genus of Hersiliidae, tree trunk spiders that was first described by B. Baehr & M. Baehr in 1987. Like other members of the family, they may be called two-tailed spiders, referring to two elongated Spinneret (spider), spinnerets. The name is derived from the genus ''Tama edwardsi, Tama'' and the Ancient Greek (''wikt:-opsis, -opsis''), meaning "resembling". These spiders differ from ''Tama edwardsi'' in the more complex palpal bulb and the median apophysis that may either be coiled or have a hook- or spoon-shaped structure at its tip. These species are generally Arboreal locomotion, arboreal, where the spiders originally included in ''Tama'' in 1987 are mainly Terrestrial animal, terrestrial. Description ''Tamopsis'' species are small to medium-sized spiders. Females of the type species ''Tamopsis eucalypti'' have a body length of about , and males have a body length of about . They resemble other members of the family Hersiliidae in having unusually long poste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
