| Comment | Sympatry: C. ocellata (in the Tapajós–Xingu interfluve), C. bassleri (in the Purus–Madeira interfluve), C. olivacea (in Humaitá, Amazonas, Brazil). Habitat: leaf litter of primary and secondary ‘terra-firme’ (non-flooded) forest. |
| Etymology | The specific epithet is a noun in apposition in allusion to the dorsal scales that are not in longitudinal rows, as in his sister group, C. ocellata: from the Latin “an + ordo + squama”, meaning scales out of order. |
