| Distribution | USA (Colorado, Nebraska, SE Wyoming, NE New Mexico) Type locality: 12.8 km north of Orchard, Morgan County, Colorado |
| Reproduction | |
| Types | Holotype: UCM 11356, adult male, collected from 12.8 km north of Orchard, Morgan County, Colorado, by V. Janzen on 10 May 1958 (Fig. 11). Paratopotypes. UCM 11358–59, both males, collected by V. Janzen on 10 May 1958. |
| Diagnosis | Diagnosis: Phrynosoma bauri sp. nov. can be distinguished from other members of the P. douglasii species complex by the following combination of adult characters: (1) snout short, 44.3% ± 0.99 (38.5–50%) of orbit to rostral scale distance; (2) rostrofrontal profile rounded or angular with a steep incline; (3) frontal rim usually elevated above the occipital shelf; (4) enlarged frontal rim scales 2.84 ± 0.23 (1–4)/ 2.65 ± 0.25 (1–4); (5) temporal shelf moderately short, 16.8% ± 0.90 (11.1–24.2%) in males, 18.1% ± 0.82 (12.9–23.0%) in females; (6) temporal shelf weakly to moderately convex; (7) cephalic horns moderately short, third temporal horn length 13.7% ± 0.38 (8.0–18.5%); (8) cephalic horns usually directed upward, ca. 45° to nearly vertical; (9) tympanum elliptic, moderately broad; (10) tympanum exposed; (11) tail moderately long, 226% ± 6.20 (169–279%) in males, 199% ± 4.47 (158–235%) in females; (12) dorsal spots small, wedge-shaped to slightly rounded; (13) light-colored borders of dorsal spots confined to posterior edges; (14) dorsolateral white spots present; (15) gular area with scattered melanistic spots and vermiculations (melanin-dispersed phase); (16) abdomen with large melanistic spots (melanin-dispersed phase); (17) interrupted melanistic subcaudal bands absent or present distally, barely entering ventral surface (melanin-dispersed phase). |
| Comment | Hybridization: P. bauri hybridizes with P. hernandesi (Montanucci 2015). Distribution: see map in Montanucci 2015: 169, Leaché et al. 2021: 3 (Fig. 1, Supplementary Fig. S5). Synonymy: Leaché et al. 2021 suggested to “lump this species under Phrynosoma hernandesi”, without explicitly synonymizing it or downgrading it to subspecies. Köhler 2021 synonymized bauri with hernandesi, which is supported by Leaché et al. 2021. |
| Etymology | The subspecific epithet bauri is a Latin patronym in the genitive singular, honoring the late Bertrand E. Baur, a longtime friend and avid student of Phrynosoma. Baur died in November of 2013 due to injuries sustained in a car accident the previous year. |
