FIGURE 12. Bairdoppilata hirsutella Maddocks, n. sp. A–C, molting juvenile specimen 689J, USNM 139894, instar A–1: A, LV interior in reflected light, with narrow infold, broad but weakly calcified inner lamella, and vestibules partly filled with fluid; B, LV interior in reflected light, with AMS, showing striated, hummocky texture of inner chitinous lining, as sensilla and cuticle are being withdrawn from older valve; C, anterior margin of RV interior in reflected light, showing narrow (normal) infold. D–K, holotype adult male specimen 634M, USNM 139891: D–E, LV and RV interiors in reflected light, with broad calcified inner lamella, shallow vestibules separated ventrally, prominent selvage and fringes; F, RV interior, posterodorsal edge with denticles of supplemental dentition; G, LV interior, posterodorsal edge with locules of supplemental dentition beneath dorsal overhang; H–I, RV and LV exteriors in transmitted light, with broad (normal) inner lamellae, fairly deep vestibules, NPC, sensilla, and AMS; J–K, RV and LV exteriors in reflected light, showing smooth surface and sensilla; RV caudal process is damaged. L–M, adult female specimen 635F, USNM 139892: RV and LV exteriors in transmitted light, with AMS and sensilla. Scale bar = 50 µm.
