Diagnosis.

As in Villalobos and Alvarez (2003).

Distribution.

This species is distributed in and around the town of Santa María Jacatepec in northern Oaxaca, Mexico (Fig. 1 ).

Remarks.

As noted by Villalobos and Alvarez (2003), the G1 of T. jacatepecensis is morphologically similar to those of T. complanata and T. lamellifrons (Figs 8 , 9 ), and coincidentally the three species together with T. ayotzintepecensis sp. nov. are also closely related genetically forming a separate clade in the phylogenetic tree presented herein (Fig. 3 ).
