Description
Original diagnose after Itano & Duffin (2023) [31683]: Known only from a rostral cartilage, which is long and narrow, gradually tapering distally. Dorsal surface with a narrow groove, which continues nearly to the distal end of the rostral cartilage. Approximately evenly spaced lateral denticles, which appear to be fused to the rostral cartilage.
