Diagnosis. This species can be distinguished from the remaining species of the puncticeps group by umbilicate punctures on the dorsal and ventral surface of the head sparse ( Figs. 2 View FIGURE 2 e, f), with several punctures (3–4) forming two short rows at center of the head, and their aedeagus moderately large (length 1.9 mm), with parameres as long as 0.27 times the length of median lobe ( Figs. 9 View FIGURE 9 e, 11e). The remaining species of the group have the dorsal and ventral surface of the head most densely punctate, not forming rows of punctures at center of the head, and the size and form of the aedeagus are not as in T. cribripennis .
Discussion. We did not observe differences in the elytral punctation and coloration, or in the apical teeth of the labrum, that were reported to be useful to separate T. cribripennis from other species, ( Sharp 1885) in the original description. However, the sparse umbilicate punctures on the head that he noted in just one specimen was found to be diagnostic in the studied specimens.
Natural history. Only four specimens are known of this species, although Veracruz, particularly Cordoba and surroundings, have been sampled for many years, an aspect that probably denotes the demographic rarity of the species, which has been collected with carrion traps (2 specimens) and flight interception trap (1 specimen). This also denotes similar life habits to those of remaining species of the puncticeps group, which frequent the soil of the forest and their distinct microhabitats, as leaf litter, logs, rocks, etc.
Distribution ( Fig. 13 View FIGURE 13 b). Species endemic to Mexico, known from only two places close to each other, Córdoba and Ixtaczoquitlán, in Veracruz ( Table 2 View TABLE 2 ) ( Sharp 1885, Navarrete-Heredia et al. 2002). The record of the species in Hidalgo (La Misión) given by Márquez (2006) is a mistake due to a misidentification.
