Fig. 16. Hyoid and branchial arches of Nematolebias papilliferus, male, UFRJ 4652. (a) left and median portion of hyoid arch and ventral part of branchial arches, dorsal view; (b) dorsal part of branchial arches, ventral view; (c) left hyoid bar, lateral view. ACH = anterior ceratohyal; B1-3 = basibranchials 1-3; BB = basibranchial cartilage; BC = basihyal cartilage; BH = basihyal; C1-5 = ceratobranchials 1-5; DHH = dorsal hypohyal; E1-4 = epibranchials 1-4; H1-3 = hypobranchials 1-3; IC = interarcual cartilage; IH = interhyal; P2-3 = pharyngobranchials 2-3; PCH = posterior ceratohyal; R1-6 = branchiostegal rays 1-6; T4 = tooth plate pharyngobranchial 4; VHH = ventral hypohyal. Larger stippling indicates cartilage. Scale bar 1 mm.
