Diagnosis
Reference | Diagnosis | |
---|---|---|
J. D. Scanlon et al. 2003 | Small elapid snake with relatively elongate vertebrae, subcentral ridges not prominent and nearly parallel posteriorly, subcentral grooves weakly defined or absent, and relatively small condyle and cotyle; narrow oval prezygapophyseal facets, prominent prezygapophyseal processes extending anterior to the facets; small, rounded postzygapophyseal facets; narrow zygosphene with lateral and median lobes defined in dorsal view by discrete shallow emarginations (not broad concavities), median lobe with nearly straight transverse edge or divided by median notch; posterior margins of neural arch sinuous in dorsal view, producing a narrow and acute median emargination. Maxilla with fang weakly curved, its surface ornamented with fine longitudinal ridges; palatine process with short and blunt posterior extension medially; ectopterygoid process a blunt, medially directed triangle; five or more small, solid posterior teeth following a diastema longer than the fang, the second solid tooth level with the apex of the ectopterygoid process; fourth and subsequent solid teeth on a narrow posterior process defined by concavities on both sides. Dentary with relatively small, uniform, closely spaced teeth in middle of element, with four alveoli between mental foramen and anterior apex of lateral notch for surangular. |
