Etymology. The name of the species is descriptive for the medial broad caudoventral pygofer process.

Remarks. From T. protriangulata to which it is similar in pygofer features, T. mediolata can be distinguished by the broad caudodorsal processes with abruptly narrowed apex in lateral view and broad in basal 3/4, broad medial caudoventral process and narrow, curved subgenital plate.
