This species is certainly very closely allied to T. [Gymnaeta) 

 bercsowskii , Adel., from occidental China and it is most difficult 

 to give a good character to separate these forms. The latter is 

 described from a single, very probably immature female, and a 

 knowledge of the subgenital plate of the 9 and epiphallus of thee 

 will be necessary to identify these two species with certainty. Yet" 

 I do not think there is the least doubt as to the validity of both 

 of them as species of this group, chiefiy the carvernicolous ones, 

 prove to have a very restricted geographical distribution.
