"The South American spider genus Trachelopachys is redefined on the basis of genitalic characters; the 11 known species are diagnosed, described, and assigned to species groups. A proposal to unite the tracheline, castianeirine, and corinnine clubionids in a separate family, Corinnidae, is rejected; two characters used to support this grouping (the purported absence of dorsal tarsal trichobothria and of feathery setae) are shown to be invalid, and the genitalic similarities between the trachelines and castianeirines are considered symplesiomorphic. A cladistic analysis of the known Trachelopachys is presented, and an attempt made to correlate the inferred branching sequence with the geographical distribution of the species. Four new species are described: T. tarma and T. machupicchu from Peru, T. magdalena from Colombia, and T. ignacio from Paraguay. Trachelopachys albicans Mello-Leitão is newly synonymized with T. cingulipes (Simon). The male of T. bicolor Chamberlin and the females of T. sericeus (Simon), T. bidentatus Tullgren, and T. gracilis (Keyserling) are described for the first time. Trachelopachys fasciatus Mello-Leitão, T. gulosus Mello-Leitão, and T. segmentatus Mello-Leitão are tranferred to Trachelas; Trachelas keyserlingi Roewer and Trachelas gracilis Keyserling are transferred to Trachelopachys. In a supplement, the genus Tetratrachelas Caporiacco is newly synonymized with Trachelopachys, and Meriola discolorifemur Caporiacco is transferred to Trachelopachys and newly synonymized with T. singularis (Caporiacco)"--P.
