Bronchocela hayeki, also known commonly as the Sumatra bloodsucker, is a species of lizard in the family Agamidae.

[2] B. hayeki is named after the Austrian-German painter Hans von Hayek, who spent many years in Indonesia and Ceylon during World War I.

[1][2] The preferred natural habitat of B. hayeki is forest, at altitudes of 300–1,400 m (980–4,590 ft), but it has also been found in disturbed areas such as plantations, gardens, and villages with shrubs and trees.

The lips, the area around the eye, and the typanum (ear drum) are brownish black.

Males may attain a snout-to-vent length (SVL) of 12 cm (4.7 in).
