Pseudalsophis steindachneri, also known commonly as the Galápagos painted racer, Steindachner's snake, and the striped Galapagos snake, is a species of snake in the subfamily Dipsadinae of the family Colubridae. The species is indigenous to the Galápagos Islands of Ecuador.
Pseudalsophis steindachneri is named after Franz Steindachner, an Austrian zoologist, ichthyologist, and herpetologist, who published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Pseudalsophis steindacneri has smooth dorsal scales, which are arranged in 19 rows at midbody and lack apical pits. The ventrals number 169–180, and the subcaudals number 96–114.
In the Galápagos Islands, Pseudalsophis steindachneri is found on the following islands: Baltra, North Seymour, Rábida, Santa Cruz, and Santiago. The preferred natural habitats of Pseudalsophis steindachneri are forest and shrubland, at elevations from near sea level to 100 m (330 ft).

With luck
About 10% of wildlife watchers report a Striped Galapagos Snake sighting in Galápagos Islands on a given day, based on 63 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 18th most-seen of the 31 reptiles we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Striped Galapagos Snake in Galápagos Islands on a given day, against under 5% in March, the lowest month. That is one of Galápagos Islands's driest months, with almost no rain against 50 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Striped Galapagos Snake sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Galápagos Islands, in our data
Galápagos Islands is the only park on Wallace's Line with enough records to rate Striped Galapagos Snake sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Pseudalsophis
The closest relatives of the Striped Galapagos Snake that you can see in Galápagos Islands (genus Pseudalsophis, Galápagos and Elegant Racers) are Fernandina Racer (about 10%), Santa Cruz Racer (about 10%) and Darwin's Racer (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Striped Galapagos Snake is recorded against all the reptiles logged in Galápagos Islands (63 verified sightings from 2019 to 2026), 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.
