Types | Holotype: BMNH 1946.1.21.48. Holotype: USNM 29769 [Colorhogia dedimita] Holotype: USNM 12421 [Arrhyton fulvum] |
Diagnosis | Diagnosis (genus): The single genus in this subtribe has 17 midbody scale rows, 107–189 ventrals, 52–140 subcaudals, one apical scale pits, 6–7 upper labials, 7–9 lower labials, 15-20 total maxillary teeth, and 20-28 dentary teeth (Table 2). It can be distinguished from the other two subtribes in the Tribe Alsophiini by its low number of dentary teeth (10–17 versus 17–35 in Alsophiina and Uromacerina) and a derived hemipenial character: the medial papillate crest extends from the lobular crotch to the edge of the capitulum on each lobe, and forms a Y-shaped structure on the distal region of the body (Zaher 1999). HEDGES et al. (2009) defined a subtribe Arrhytonina that is identical to the genus Arrhyton. Additional details (46 characters) are available for collaborators and contributors.
