CommentSynonymy that of PETERS & OREJAS-MIRANDA 1970.

Diagnosis. Distinguishable from other mainland congeners by the following combination of characters: (1) 164–183 ventrals (vs. 154–155 in T. grapiuna, 146–160 in T. taczanowskyi, and 200 in T. battersbyi); (2) dorsal scales at midbody usually 21 or 23, rarely 25 (vs. 23 dorsals at midbody in all other mainland species); (3) vertebral scale row usually enlarged, wider than long (vs. verte- bral scale row not distinctly enlarged in size relative to remaining dorsals in T. battersbyi, T. grapiuna, and T. taczanowskyi); (4) dorsals smooth or feebly keeled (vs. dorsals strongly keeled in T. grapiuna and T. taczanowskyi); (5) interparietals usually lacking, but small when present (vs. interparietals present in T. battersbyi and T. grapiuna, usually present in T. taczanowskyi, well developed in the three species); (6) parietals in broad contact along middorsal line of head, even when interpari- etals are present (vs. parietals fully separated by interparietals in T. battersbyi and T. grapiuna); (7) maxillary teeth 15–19 (vs. 12 in T. battersbyi); (8) body spotted, dorsal spots small, with a diameter of approximately two dorsals, and irregular in shape (vs. dorsal spots large, rounded or elliptical, up to four scales in diameter in T. battersbyi); and (9) eight spot rows around body six on dorsum and two on venter (vs. six spot rows around body, four on dorsum and two on venter in T. battersbyi) [CURCIO et al. 2012].

Comparisons. Ventral counts of T. paucisquamis are apparently intermediate among South American taxa. However, with the evidence at hand, it is the only mainland species to have a good proportion of specimens with 21 dorsal scales at midbody (approximately 41% of our sample). Nonetheless, this observation is not decisive because other mainland taxa are known by considerably smaller samples. Subcaudal counts of T. paucisquamis may be high (up to 38), overcoming T. taczanowskyi and T. grapiuna, but not T. battersbyi (41 subcaudals in the only known specimen). The enlarged scales of the vertebral row of dorsals, present in most specimens of T. paucisquamis, do not occur in T. battersbyi, T. grapiuna, and T. taczanowskyi [CURCIO et al. 2012].
