Marachernes simulans is a species of pseudoscorpion in the Chernetidae family.

It was described in 1992 by Australian arachnologist Mark Harvey.

The specific epithet simulans comes from the Latin simulo ('imitate' or 'copy') with reference to the similarity between this species and Marachernes perup.

The colour is mainly yellow-brown, with the carapace and pedipalps dark red-brown.

The type locality is Upper Beaconsfield, some 45 km south-east of the centre of Melbourne, where the pseudoscorpions were collected from beneath tree bark.
