[4] This genus was first described by the Austrian myriapodologist Carl Attems in 1904 to contain the newly discovered type species T. fastigata, found in Kyrgyzstan.

[7] In 1979, the Russian myriapodologist Sergei I. Golovatch of the Academy of Sciences of the Soviet Union described another species in this genus, T. ornata, found in Kazahkstan.

[10] In 1988, the French myriapodologist Jean-Paul Mauriès of the Muséum National d'Histoire Naturelle in Paris described another four species, T. jaljalensis, T. katmandua, T. mangsingma, and T. smetanai, all found in Nepal and all featuring only 29 segments as adults.

[2][4] The anterior gonopods appear complex in this genus, with several bundles of long hairs or thin strips.

The basal (coxal) elements of these gonopods are separated down the center into distinct left and right parts.

[3] Species in this genus arrive at a lower number of segments and legs through a process of post-embryonic development that deviates from the anamorphosis usually observed in the order Chordeumatida.
