FIGURE 1. A–K, Bairdoppilata alcyonicola Maddocks. A–E, molting juvenile specimen 523J: A, RV exterior, showing puncta, sensilla, NPC, inner margin, weakly calcified proximal zone of inner lamella, narrow infold, and marginal frills; ventral edge is damaged; B, posterior caudal angle of RV exterior, showing inner margin, weakly calcified inner lamella, narrow infold, marginal sensilla, and frill; C, anterior margin of RV exterior, with inner margin, weakly calcified inner lamella, infold, marginal sensilla, and frill; D, A2 distal claws, molting; E, zygum and both furcae. F–H, molting juvenile specimen 524J: F, A2 distal claws, molting; G, plate of EV, with uniform row of teeth; H, LV exterior, molting; folded sensilla of new valve are visible beneath old valve. I–K, molting juvenile specimen 168J: I–J, RV and LV exteriors, showing inner margin, broad but weakly calcified inner lamella with continuous vestibules, narrow infold, and characteristic patch pattern; anterodorsal edge of LV is damaged; K, exterior view of posteroventral edge of LV, showing sensilla of new valve folded chevron-style within vestibule of instar. L–Q, Bairdoppilata cratericola Maddocks. O–P, juvenile specimen 973J: L, A2 claws; M, plate of EV. N–Q, adult female specimen 972F: N, genital lobe and spermatophore; O, RV exterior, with low focus to show broad infold, well calcified inner lamella, shallow, separate vestibules, and marginal frills; P, LV exterior, high focus to show puncta, NPC, MSP, and patch pattern; Q, A2 distal claws. Scale bar = 50 µm.
