Type locality: Parque Nacional “Henri Pittier”, Rancho Grande, Venezuela.  
TypesHolotype: MBUCV 3046, a 345 mm male (L. Aristeguieta, April 1953). 
DiagnosisDiagnosis (genus Umbrivaga): This genus is related to the Leimadophis,Liophis and Urotheca assemblage of snakes, but its dentition differs from that of any of the genera in this complex. The teeth on the maxilla are directed inward, so that the axis of each tooth is almost horizontal. There are only 6 + 2 to 7 + 2 maxillary teeth, the last two considerably enlarged, lance-shaped, and separated from the rest by a large diastema (Fig. 1 in Roze 1964). Moreover, there is a shelf-like anterior projection of the premaxilla (Fig. 2 in Roze 1964), not observed in any related genus. Table 1 (Roze 1964: 535) summarizes the diagnostic characteristics of the genera Leimadophis, Lygophis, Liophis, Urotheca, and Umbrivaga).

Diagnosis (mertensi): The distinguished characters of the genus which appears to be monotypic also serve to diagnose the species. Moreover the frontal plate is large, approximately as long as the parietale and longer than its distance to snout. There are 126 to 131 ventrals and 59 to 60 paired subcaudals; 7 supra-labials (3rd and 4th entering eye); 17-17-15 dorsals, smooth without apical pits (Roze 1964: 536). 
CommentType species: Umbrivaga mertensi ROZE 1964 is the type species of the genus Umbrivaga ROZE 1964. The genus has been synonymized with Erythrolamprus by Grazziotin et al. 2012.
