A Kinabalu Sticky Frog (Kalophrynus baluensis) hiding in the leaf litter
The various Borneo Kalophrynus species are hard to tell apart and something of a taxonomic mess. Fortunately for the sake of identification only one type is known from Mt. Kinabalu, and it seems to be a well-defined species.
Kalophrynus baluensis is a species of frog in the family Microhylidae. It is endemic to Mount Kinabalu in Sabah.
''Kalophrynus baluensis'' is unusual in that it appears to have diverged from its closest known relative that is not endemic to Mount Kinabalu before the mountain reached its present elevation. Most other Mount Kinabalu endemics are younger than the mountain , and thus appear to have evolved there relatively recently.
