Genitalia of the female holotype of the Central Asian species Furcula terminata (Wiltshire, 1958) (TL: northeastern Afghanistan) were studied for the first time. They showed a clear similarity with the genitalia of Furcula gorbunovi Schintlmeister, 1998 (TL: Gissar Range, Tajikistan) and Furcula mimonovi Schintlmeister, 1998 (TL: Karakalpakstan, Uzbekistan). Males of F. terminata from Afghanistan were not found in the collections. However, the specimens from neighboring Tajikistan and topotypes of F. gorbunovi and F. mimonovi were studied and all of them have pointed apex of the costal process of valva specific for the bifida-group, not the furcula-group as suggested previously. Considering the morphological similarity and overlapping distribution areas of the three studied taxa, two new synonyms are established for F. terminata: F. gorbunovi syn. n. and Furcula mimonovi syn. n. The population of Tian Shan and Alay Range in Kyrgyzstan and Uzbekistan, previously regarded as F. terminata, are described here as a new species based on differences in the genitalia of both sexes.
