FIGURE 1 in New Austrognathiidae (Gnathostomulida: Conophoralia) from Hong Kong and Japan: microscopic anatomy, ultrastructure and evolutionary implications
FIGURE 1. Austrognathia glandifera sp. nov.; reconstructions to show structures important for species determination. Sclerotized pharyngeal structures are shown as dorsal views and are shaded according to the phase effects of the phase-contrast microscope. These effects, such as the dark of the teeth and of the edges of the basal plate, are artefacts and don't represent real structural differences as implied. Some viewing them with bright-field, oblique illumination, or DIC would not see them. A, B. Basal plates. C, D. Jaws. E. Different developmental stages of conuli. Scale bars: 10 µm.
FIGURE 5 in New Austrognathiidae (Gnathostomulida: Conophoralia) from Hong Kong and Japan: microscopic anatomy, ultrastructure and evolutionary implications
FIGURE 5. Austrognatharia orientis sp. nov.; photomicrographs of adult specimens. A. Dorsal view of whole specimen. B, C. Pharynx with basal plate and jaws at different focal planes. D–G. Different developmental stages of conuli of specimens from Hong Kong. H–O. Different developmental stages of conuli of specimens from Japan. Scale bars: A 100 µm; B, C 5 µm; D–G 5 µm; H–O 5 µm.

FIGURE 7 in New Austrognathiidae (Gnathostomulida: Conophoralia) from Hong Kong and Japan: microscopic anatomy, ultrastructure and evolutionary implications
FIGURE 7. Austrognatharia orientis sp. nov.; electronmicrographs of conuli of specimens from Japan (A–E) and Hong Kong (F, G). A. Spermatogonium and late spermatid lying next to each other. B. Late stage of spermatid with slightly chaotic distribution of mitochondria. Note that the nurse cell entirely encloses the spermatid, especially the small rim of cytoplasm on the left side. C. Later stage of conulus with restricted distribution of mitochondria below the cingulum but no maturation layer. D. Cross section through the same developmental stage as in C. E. Sagittal section through apical part of mature conulus showing the cellular membrane, the maturation layer and the electron-dense cingulum. F. Sagittal section through conulus in stage of disintegration embedded within the bursal tissue. Note maturation layer above the cingulum. Inset: Magnification of basal body. G. Cross section through conulus in stage of disintegration embedded within the bursal tissue. Note maturation layer surrounding the cingulum. Inset: Magnification of basal body. Abbreviations: nc nurse cell, sd spermatid, sg spermatogonium. Scale bars: A, B, C, D, F, G 2 µm; E 200 nm.

FIGURE 6 in New Austrognathiidae (Gnathostomulida: Conophoralia) from Hong Kong and Japan: microscopic anatomy, ultrastructure and evolutionary implications
FIGURE 6. Austrognatharia orientis sp. nov.; electronmicrographs of protonephridia (A–E) and the male copulatory organ (F, G). A. Cilium and microvilli with indentation of terminal cell. Arrowheads point to origin of filamentous rods. B. Cross section through terminal cell and canal cell at a plane proximal to the termination of the microvilli of the terminal cell. C. Cross section through terminal cell and canal cell distal to the termination of the microvilli of the terminal cell. Arrows point to ECM. D. Detail of C showing the protonephridial canal and the surrounding six rods of filamentous material. Note that the rods are clearly an intracellular part of the canal cell. E. Section through the nephroporus showing the nephroporus cell and the canal cell. Note the cilium reaching from the protonephridial duct into the nephroporus and the many microvilli of the nephroporus cell. Asterisk marks the cilium of the terminal cell, arrowhead points to centriole of the nephroporus cell. F. Distal part of penis with electron-lucent vesicles. Arrows point to the basal matrix at the base of the penis cells. Note microvilli in the ejaculatory duct. G. Distal, glandular part of male copulatory organ enclosing a mature conulus.
