Summary:
Males have the lower two thirds of the body between the second dorsal and anal fins, and the caudal peduncle bright red in colour, and a dark stripe along the midsides from behind pectoral-fin base to below the origin of second dorsal fin. In females, this stripe ends in a small spot on the caudal peduncle.

A very small rare freshwater goby found in clear, fast flowing, steep rainforest streams in the Wet Tropics region of northern Queensland.
