(A) Metabasal armature immediately anterior to the basal armature; nine hooks transitioning to eight hooks per
principal row (AHC 35424; voucher [paratype of Prochristianella jensenae Schaeffner & Beveridge, 2012b]). (B) Metabasal armature ~320 μm anterior to the basal armature; paired principal rows sharing an eighth hook (LRP 10603; paratype). (C) Metabasal armature ~205 μm anterior to the basal armature; eight hooks
transitioning to seven hooks per principal row (LRP 10604; paratype). (D) Metabasal armature ~305 μm anterior to the basal armature; seven hooks with an occasional eighth hook per principal row (USNM 1661589; paratype). Hooks are colored by principal row. For hooks 8(8′) and 9(9′), hooks missing their complementary hook are denoted in black font with an asterisk (*).
