Four-lined Tree Frog (Polypedates leucomystax)
Some herps know how to live up to their common names, and this medium-sized treefrog did indeed have four lines down its back. You might think that wouldn't be too much to ask, but tell that to the Four-striped Bent-toed Geckos.

My Travelogues and Trip Lists page includes a complete list of the herps I saw in the wild on this trip to Malaysia, as well as a travelogue of the trip.

Kubah National Park, Sarawak, MalaysiaJanuary 27, 2017
Four-lined Tree Frog (Polypedates leucomystax)
Some male frogs inflate huge vocal sacs when calling for mates. These guys are a little more modest, but they still get the gals.
Kubah National Park, Sarawak, MalaysiaFebruary 19, 2018
Four-lined Tree Frog (Polypedates leucomystax)
This frog is found throughout Borneo in disturbed habitats; they do well wherever people go. Kubah doesn't seem like your classic disturbed habitat, but it is reasonably close to Kuching and gets a lot of visitors, so possibly these frogs came along for the ride at some point in the past.
Danum Valley Conservation Area, Sabah, MalaysiaMarch 7, 2018
Four-lined Tree Frog (Polypedates leucomystax)
Danum Valley is one of the largest remaining primary lowland rainforests in all of Asia, but that's not enough to keep out the riff-raff, it seems.
