Claspers small to medium (postcloacal length about 17–21% TL when mature); lacking spur, palp and pseudosiphon; rhipidion present; shield narrow laterally, with an expanded medial arm that wraps over ventral surface and fuses to axil cartilage; sentinel and spike simple with pungent, slightly flattened, recurved tips; sentinel capable of strong anteromedial rotation (almost forming 180° angle with spike when clasper everted); two dorsal terminal cartilages but dorsal terminal 1 absent; distal projection of dorsal terminal 3 not forming an obvious spur; axial tip simple, not spatulate or with a corrugated margin; accessory terminal 1 simple, apex weakly or strongly blade like, not spoon-shaped; accessory terminal 2 simple, slender, forming a spiral projection, attachment process poorly developed; monospondylous vertebrae mainly exceeding 25.
