Hebius sauteri, commonly known as Sauter's keelback or the Kosempo keelback, is a species of snake in the family Colubridae. The species is endemic to Asia. The specific name, sauteri, is in honor of German entomologist Hans Sauter.
H. sauteri is found in southern China, Taiwan, and northern Vietnam. The preferred natural habitats of H. sauteri are freshwater wetlands, grassland, shrubland, and forest, at altitudes of 580–1,450 m (1,900–4,760 ft). H. sauteri is oviparous.

Rare
Under 5% of wildlife watchers report a Kosempo Keelback sighting in Taipei on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 34th most-seen of the 35 reptiles we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Kosempo Keelback in Taipei on a given day, against under 5% in October to August, the lowest months. That is one of Taipei's wettest months, with about 240 mm of rain against 90 mm in February.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Kosempo Keelback sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
Only Taipei, in our data
Taipei is the only city on Wallace's Line with enough records to rate Kosempo Keelback sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Colubridae
The closest relatives of the Kosempo Keelback that you can see in Taipei (family Colubridae, Colubrid Snakes) are Red-banded Snake (about 10%), Kelung Cat Snake (about 10%) and Chinese Green Snake (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Kosempo Keelback is recorded against all the reptiles logged in Taipei (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.
