[4] The specific epithet, yuwonoi, is in honour of Indonesian herpetologist Frank Bambang Yuwono (born 1958).

[2] The fully mature size of tricolor monitors is currently unknown, owing to the great difficulty of observing this species.

The largest individual recorded was 1.46 metres (4.79 feet) in total length (including tail) but was not fully grown.

[7] The tail is heavily compressed and the teeth are proportionately very long compared to most monitors, even those which it is closely related to.

They frequent nest mounds excavated by megapodes, which attract smaller birds as well as small reptiles and insects that they may take as prey with their unusually long teeth.
