The unicolor cribo (Drymarchon melanurus unicolor) is a Central American subspecies of the cribo snakes.

The eastern indigo snake, Drymarchon corais couperi is another subspecies of this genus.

Until recently the unicolor cribo was considered a subspecies of the same species as the indigo snake Drymarchon corais unicolor.

Unlike the indigo snake, which is dark blue to almost black, the unicolor cribo has a yellow or golden color with black facial and neck bar-like markings.

Its prey consists of other snakes, including venomous snakes, small mammals, small birds, lizards, frogs, fish, and other small vertebrate animals.
