The specific epithet ischnoryctes comes from the Greek ischnos (‘lean’ or ‘thin’) and oryktes (‘digger’), with reference to the slender pincers of the male.

The pincers of the female are slightly shorter and more robust than those of the male.

[1] Specimens of the species were collected near Mount Mulligan, west of Mareeba and the Atherton Tableland, in savanna woodland containing patches of vine thicket, at the base of the large sandstone Ngarrabullgan mesa which provides orographic moisture to its surrounds.

[1] The scorpions dig vertical burrows up to 30 cm deep, with a terminal chamber and slit entrance.

They also shelter in rock crevices and beneath stones in the vicinity of creeks and pools.
