This shrimp is known from the Pacific, from the Philippines to Samoa.
In the examined specimens, the rostrum is not strongly flattened from side to side.
It favours fast-flowing fresh water and gathers in large numbers on rocky walls below waterfalls.
In the examined specimens, the fingers of the first two pairs of chelae end in brushes of long hairs.
In the examined large males, a prominent spur occurs on the merus of the third pereiopod.
