Charon trebax is a species of amblypygid arachnid (whip-spider) in the Charontidae family.

It was described in 1998 by Australian arachnologists Mark Harvey and Paul West.

The specific epithet trebax (Latin: ‘crafty’ or ‘cunning’) alludes to the species’ elusiveness and the difficulty in obtaining specimens.

[1][2] The species occurs in North Queensland.

The type locality is Emmett Creek, Cromarty, some 40 km south-east of Townsville.
