Trachelopachys is a genus of South American araneomorph spiders first described by Eugène Simon in 1897.^[2] Originally placed with the Corinnidae, it was moved to the Trachelidae in 2014.^[3]

Description

Spiders in this genus have a characteristically dark, often jet black, carapace. The legs are reddish, and typically have dark annulations. As with most trachelids, species of Trachelopachys have no leg spines, however they do bear rows of short, thick, black cuspules on the distal segments of the front two pairs of legs.^[4]

As of April 2019^[update] it contains fifteen species throughout South America:^[1]
