| Distribution | Honduras (endemic of Roatan Island) Type locality: approx. 4.8 km (3 miles) west of Roatán on the path to Flowers Bay, Isla de Roatán, Departamento de las Islas de la Bahía, Honduras.” |
| Reproduction | oviparous |

| Diagnosis | Diagnosis: Ctenosaura oedirhina is distinguished from all other Ctenosaura by its blunt, rounded snout (Fig. 2) resulting from inflation of the nasal capsule. In addition, C. oedirhina is distinguished from C. acanthura, C. hemilopha, C. pectinata, and C. similis by the enlargement of the scales on the proximal anterodorsal surface of the shank, a character shared with C. bakeri, C. clarki, C. defensor, C. palearis, and C. quinquecarinata. Ctenosaura oedirhina can be distinguished from C. clarki, C. defensor, and C. quinquecarinata within this latter group by its larger maximum size (Table 1), mode of 24 rather than 25 presacral vertebrae, possession of four rather than two postmental scales, and separation of more than one of the first 10 whorls of enlarged and spinous caudal scales by two rather than one row of smaller scales. These characters occur also in C. bakeri, and all but the last occur also in C. palearis. Ctenosaura oedirhina is distinguished from C. bakeri and C. palearis by its relatively slightly compressed dorsal crest scales and the absence of a pendulous dewlap. Other comparisons are presented in the sections on differences between C. bakeri and C. oedirhina and the phylogenetic relationships of C. oedirhina.

| Comment | Considered as Ctenosaura bakeri by BARBOUR 1928 or Enyaliosaurus bakeri by COCHRAN 1961. |
| Etymology | The specific name oedirhina is formed from the Greek oedos (or oidos; a swelling) and rhinos (nose), and refers ‘‘to the profile of the [swollen] snout compared with those of other Ctenosaura’’ (de Queiroz, 1987: 892). |
