Gonatotrichus minutus is a species of millipede in the family Siphonophoridae, described in 1922 by the Swiss zoologist Johann Carl. The species is endemic to Malaysia. Individuals are very small, around 5mm long and, 0.7 mm wide, with around 40 body segments. The color is brownish-yellow, with lighter-colored legs. It differs from other Malaysian siphonophorids by its small size, the aspect ratio of its beak and antennae and the shape of the front gonopods.[1]
