Figure 2 Landmarks (pink dot) and semi-landmarks (red diamond) used in geometric morphometrics. Photographs of B. cheni, IHB 202303064716, 42.7 mm SL. A. Lateral view of head; 1–5 landmark points (anterior-most tip of snout, topmost, hindmost and lowermost point of gill opening, and pectoral-fin insertion), and 6–20 semi-landmark points to which the curve from the maxillary-barbel root to the posteromedial tip of the supraoccipital was resampled by length; B. Ventral view of head; 1–6 landmark points (roots of left and right maxillary barbels, left and right lateral end of upper lip, anterior-most tip of snout, and median point of distal margin of upper lip), and 7–19 semi-landmark points to which the curve between the left and right end of the rostral groove was resampled by length.
