Sarawak Keelback, Hebius sarawacensis (Günther, 1872) – of Sarawak / Borneo – 2023m ASL
This Hebius sarawacensis is nothing special at first, but where I found it it is. The second edition of “Snakes of Borneo” gives the maximum altitudinal distribution of this species as 1675m ASL. This individual I found at 2023m ASL only a few meters below a mountain ridge, so this record sets a new record for the vertical distribution of this species. Hebius sarawacensis can be found between 50m and 2023m ASL – here the species has partly clear color differences of the single local morphs.
