Rami outline longer than wide, ratio length:width of closed rami 1.7−1.9; outer margin of rami weakly concave dorso-laterally, rounded-angular posteriorly; outer ventral margin with carina rami near 3/7 from apical ramus tip; median rami opening elongate drop-shaped. Each ramus with single, slightly offset apical tooth set at right angle to trophi axis; cardal apophyses very small. Prior to apical teeth a preuncinal tooth set at a right angle to trophi axis; preuncinal teeth with elongate triangular head and short shaft forming obtuse angle; head with small cardal apophysis. Fulcrum longer than ramus, in dorsal/ventral view distal end slightly widening and indented dorsally; in lateral view with broad base, quickly tapering, continuing parallel-sided. Unci medium long, slightly curved, head slightly shorter than shaft, with dorsal and ventral apophyses. Intramallei long, sock-shaped, with relatively long, rounded medio-lateral basal expansion bearing medio-caudal opening; inner side expaned, fitting lateral concavity of rami. Supramanubria absent. Manubria slightly less incus length, stout, rod-shaped, proximal half straight, distal half incurving with crutched cauda, head short, rounded-triangular.
