Trachelidaeis a family ofaraneomorphspiders(more recently evolved spiders with inward-pointing chelicerae) first described byEugène Simonin 1897 as a subfamily called "Tracheleae" ( "Trachelinae" in modern terminology).[2]The Trachelidae family, also known as "ground sac spiders", is within the group of spiders known as theRTA clade,which includes mostly wandering spiders that do not use webs. Spiders in the Trachelidae family are characterized as being 3-10mm long and having a red cephalothorax and a yellow/tan abdomen. They are commonly found indoors.[3]It was placed in the familyClubionidae,then later inCorinnidaewhen the Clubionidae were split up. The first study that suggested Trachelidae should be considered its own family was done by Deeleman-reinhold in 2001 as part of an analysis of RTA Clade spiders.[4]An analysis byMartín J. Ramírezin 2014 suggested that it was not closely related to other members of the Corinnidae, and was better treated as a separate family.[5]It was then placed in theCTC cladeof spiders, or the Claw Tuft Clasper clade,[6]which is a group of spiders that have two tarsal claws with tufts of hair.[7]

A majorsynapomorphyof Trachelidae is the reduction of leg spines. Other synapomorphies of the family include no scales, no epiandrous spigot, only one major ampullate gland in females, no median apophysis, and the secondary spermatheca are the same size as the primary.[8]Currently, there are271 known speciesacross 20 genera.
