Diagnosis: An extremely small species of rhamphorhynchid with a wing span of only about 40 cm. Tooth crowns are relatively high, acute, and slightly recurved. Cervical vertebrae are short and thick. Tail is long with distinctly elongated neural spines and haemal arches on the medial and posterior caudal vertebrae. Wing metacarpal is robust with slight posterior curvature and a length only one-quarter that of the radius. Wing finger is slender and long; the first phalanx is distinctly longer than the second phalanx, and the second phalanx is only slightly longer than the radius. Tibia is shorter than the humerus. Fibula is conspicuously present but is slender and weak, and half as long as the tibia. Metatarsals I-IV are nearly equivalent in length but metatarsal V is short and straight. The fifth pedal digit has two extremely well developed phalanges that are two-thirds the length of the metatarsals, and the ungual is curved with an acutely tapered end. (Ji S. & Ji Q., 1998)
