Abstract
Trachelas L. Koch, 1872 is a large and diverse genus of sac spiders, originally placed in the family Drassidae Koch. Simon (1897) transferred Trachelas to the family Clubionidae Wagner, 1887 in the Tracheleae group Karsch, 1880, under the subfamily Corinninae Karsch, 1880. Corinninae was elevated to family rank by Lehtinen (1967). Lehtinen (1967) did not refer to the Trachelineae group in that publication; however, in a later publication he refers to the family Trachelidae, without justification for family elevation (Lehtinen 1996). Therefore, Trachelinae remained a subfamily of Corinnidae Karsch, 1880 until 2014 when it was elevated to family rank by Ramírez (2014).
