Appendage numbers count as post-antennular appendages. Note that in a no segmental mismatch is pictured, giving nine tergites and nine pairs of appendages, in total 17 post-antennular appendage pairs. In h, i there are still seven tergites, with te7 as a diplotergite carrying two appendage pairs; 16 post-antennular appendage pairs in total. an, antennulae; as, antennular scale; ba, basipodite; bn, basal most antennular articles; db, dorsal bulges; ec, eye cavity; en, endopod; ex, exopod; ey, eye; he, head; hy, hypostome.
