The goblin spider genus Dysderina Simon is relimited to include only those members of the Dysderina complex that have three pairs of deep, steeply sided excavations extending from the sides of the sternum toward the midline; two species groups are recognized. The principalis group contains those species whose members have strong, transverse ridges connecting the posterior edges of each pair of sternal excavations, including the type species, D. principalis (Keyserling) from Colombia (the female of which is described for the first time), plus seven new species from Colombia (D. sasaima, D. cunday, D. amaca) and Ecuador (D. sacha, D. erwini, D. baehrae, D. excavata). The tiputini group contains species whose members lack transverse sternal ridges, and includes five new species from Ecuador (D. tiputini), Colombia (D. ayo, D. matamata, D. craigi), and Brazilian Amazonia (D. urucu). A new genus, Tridysderina, is established for a group of species whose members have a flat, smooth sternum with one or two transverse ridges at the level of coxae II and III, but without a transverse ridge at the level of coxa IV; the genus includes six new species from Ecuador (T. yasuni, T. jatun, T. galeras, T. archidona, T. tena, T. bellavista).
