Gloydius brevicauda is a pit viper species endemic to China and the Korean Peninsula. Common names: short-tailed pit viper, short-tailed mamushi. Adults are relatively stout with a broad head and a short tail. (The subspecific name, brevicaudus, is Latin for "short tail".)
The largest male examined by Gloyd and Conant (1990) was 71 cm (28 in) in total length of which the tail was 9 cm (3+1⁄2 in); the largest female, 69 cm (27+1⁄4 in) with an 8.2 cm (3+1⁄4 in) tail. On average, male specimens had a tail that was 12–15% (13.5%) of total length, while in females this was 11–13% (11.7%).
The scalation usually includes 21 rows of dorsal scales at midbody, all of which are keeled except the lowermost on the anterior part of the body. There are 135–149 ventral scales, and 30–44 mostly paired subcaudal scales. 95% of all specimens have 7 supralabial scales.
The color pattern consists of a light brown or gray ground color, overlaid with a pattern of 23–36 pairs of dorsolateral blotches or half-bands that oppose or alternate on either side of the middorsal line. These blotches are subelliptical in shape and brown in color with pale centers and dark brown to grayish brown... Wikipedia →

Possible
About 20% of wildlife watchers report a Short-tailed Mamushi sighting in Hangzhou on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 14 reptiles we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Short-tailed Mamushi in Hangzhou on a given day, against under 5% in October to March, the lowest months.
Yes
Of the 5 cities where we can rate Short-tailed Mamushi sightings, Hangzhou has the highest daily chance: about 20%. Next come Nanjing (China, about 20%) and Shanghai (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Short-tailed Mamushi is recorded against all the reptiles logged in Hangzhou (21 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.
