Callulops omnistriatus is a species of frog in the family Microhylidae.

The fingers and the toes have moderately expanded discs; there are well-developed terminal grooves, to which the specific name omnistriatus alludes (from Latin omnis meaning "all" and striatu meaning "grooved").

There are traces of lumbar ocelli, and a specimen had vague and faint yellow-brown dorsal mottling.

The venter is lavender, getting darker towards the chin and throat and gradually from thighs to feet.

[1] The type series was collected from 930–960 m (3,050–3,150 ft) above sea level.
