| Reproduction | ovovivparous |
| Types | Holotype: AMNH 93237, an adult male, from Mexico, Oaxaca, El Tejocote, 2377 m elevation; collected 11 October 1964 by C. M. Bogert. |
| Diagnosis | Diagnosis: Thamnophis bogerti can be distinguished from all other Mexican species of the genus by the following combination of characteristics: (1) maximum DSR 17; (2) maxillary teeth 17-20; (3) top of head unpatterned; (4) two rows of relatively small black spots between light vertebral and lateral stripes; (5) nuchal blotch coloration variable, although only 15% have predominantly brown blotches; (6) prominence of black bar along posterior suture of SL 5 equal to, or less than, bar along SL 6 and 7 suture; (7) V averaging 145 in males, 140 in females; (8) SC averaging 70 in males, 62 in females; (9) tail of moderate length (mean T/TL 25% in males, 23% in females; (10) prefrontal suture usually slightly longer than internasal suture (mean PFL/INL 106%); (11) muzzle tip usually broad (mean INR/NR 115%); (12) anterior nasal usually shorter than posterior nasal (mean AN/PN 81%); (13) parietals usually of moderate length (mean FL/PL 77%); and (14) frontal usually relatively broad posteriorly (mean FWP/FWA 79%).

| 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. Habitat: oak woodland, pine-oak forest, and pine-oak-madroño forest in the Mesa del Sur of Oaxaca, exclusive of the Sierra de Juárez. Recorded elevations that are likely to be valid range from 2195-2743 m. |
| Etymology | Named after Charles Mitchill Bogert (1908-1992), former curator of the Department of Herpetology of the American Museum of Natural History. See biographical sketches in Gans 1993 and Myers & Zweifel 1993. |
