Diagnosis.

As in Rodríguez and Smalley (1972).

Distribution.

This species occurs in the southeastern portion of the Los Tuxtlas Mountain Range, in an area that starts sloping towards the coastal plain of southern Veracruz.

Remarks.

Tehuana veracruzana is easily distinguishable from the rest of its congeners due to the very large proximal lobe of the CMP of the G1 (Fig. 8 View Figure 8 ). Although it exhibits an extreme form of the G1 it is genetically closely related to the other species from Los Tuxtlas (Fig. 1 View Figure 1 ).
