Diagnosis. This species, one of the largest in the genus, is closely related to T. magna Wesołowska & Haddad, 2009 , but may be distinguished by the characteristic shape of the retrolateral tooth of chelicerae, which is very broad (compare Fig. 186 View FIGURES 184–188 herein with Wesołowska & Haddad 2009: fig. 200).

Etymology. The name refers to the large chelicerae of this species.
