The royal ground snake (Erythrolamprus reginae) is a species of snake in the family Colubridae. The species is endemic to northern South America. Erythrolamprus reginae belongs to the genus Erythrolamprus, which contains over 50 species. The genus Erythrolamprus belongs to the subfamily Dipsadinae, which is sometimes referred to as the family Dipsadidae.
Recent phylogenetic analysis of morphological and molecular DNA evidence has shown that Erythrolamprus reginae is now likely paraphyletic. Erythrolamprus zweifeli was previously considered to be a subspecies of Erythrolamprus reginae and called Erythrolamprus reginae zweifeli. However, based on notable differences in coloration and scale counts, it is now considered to be a separate species. Erythrolamprus pseudoreginae of Tobago, named in 2019, was also previously considered to be part of Erythrolamprus reginae, but is now separate.
The relationships of Erythrolamprus species located in northern South America can be shown in the cladogram below: It feeds on frogs, frog eggs, tadpoles, fish, small birds, and lizards. In an experiment conducted by biologists from the University of California... Wikipedia →

With luck
About 10% of wildlife watchers report a Royal Ground Snake sighting in Maceió on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 12 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Royal Ground Snake in Maceió on a given day, against under 5% in March, May–July and October–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Royal Ground Snake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Maceió, in our data
Maceió is the only city on Wallace's Line with enough records to rate Royal Ground Snake sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Royal Ground Snake is recorded against all the reptiles logged in Maceió (6 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
