|Diagnosis||Diagnosis (Caaeteboia): Small (much less than 1 m), slender snakes with slender transverse (maxillary) processes of pre‐maxillae bearing a small additional process oriented posteriorly from each transverse process (these are in addition to the vomerine processes); hemipenis typically xenodontine, i.e., bilobed, semicapitate and semicalyculate; sulcus spermaticus divides on the proximal region; branches of the sulcus on the lobes with centrolineal orientation; lobes small, the medial lobe shorter than the lateral one; capitula ornamented with small, ill‐defined papillate calyces, restricted to the sulcate and lateral surfaces of the lobes; hemipenial body ornamented with well‐defined lateral enlarged spines and smaller spines covering the asulcate and sulcate sides of the organ out of the intrasulcar region; body spines decreasing in length toward the base.|
Diagnosis: C. amarali is easily distinguished from other Atlantic forest Xenodontine snakes by its light gray head and pale body coloration marked by a “V” shaped dark mark extending backwards from the parietals and forming a vertebral stripe that fades on the anterior portion of the dorsum, and a dark- brown stripe on each side of the head that extends from the nostril to the postocular region, bordering dorsally the light cream supralabials and extending as blotches to the anterior third of the body (Passos et al., 2012, Montingelli et al. 2020)
