| Comment | Synonymy: Grünwald et al. 2024 suggested that T. lineri and T. conanti are junior synonyms of T. bogerti, given their minor genetic differences. All 3 species were described in the same paper and Grünwald et al. used Article 24.2 of the ICZN 1999 Code to designate T. bogerti as senior name by the page priority. |
| Etymology | Named after Roger Conant (1909-2003), American herpetologist. |
