A name tied to a place
This stream toad is documented in Sabah, Sarawak and western Kalimantan. AMNH treats Brunei as possible rather than confirmed. Spiny skin projections and a pale shoulder patch help distinguish it.

AMNH · Ansonia spinuliferBeside streams at night
Calling males sit on low vegetation beside streams at night. Tadpoles have sucker-like mouths adapted to flowing water. Listen from an established path; stream banks and larval habitat should remain undisturbed.

Haas, Das, Hertwig and collaborators · Frogs of Borneo: spinuliferDay shelters and nighttime leaves
At Kubah, a short August 2017 tracking study followed four males beside a stream. During daylight they sheltered beneath rocks or leaf litter; at night they mostly occupied leaves fifteen to fifty centimetres above ground. Some returned to previous nighttime positions. The small sample supports local observations, rather than a universal territory size.

The aquatic young occupy clear, rocky lowland streams, especially moderate currents and riffles. Their oral sucker anchors them while they rasp algal growth from the substrate. These small, dark larvae have strong tails and low fins. Adult males keep individual calling posts on low vegetation or logs near streams.
